Break-Even & Pricing Analyzer

$29.00

a small-business owner setting or checking a price who wants to know the volume that clears their costs before they commit to the number.

Local-firstNo telemetry — nothing phones homeNo lock-inNo migration

Give it a fixed cost, a price, and a variable cost per unit and it works out your contribution margin, the number of units you have to sell to break even, the revenue that represents, and how all of it shifts across a list of candidate prices.

The price you set by feel, hoping it clears your costs

You’re pricing a product or a service, and the real question is plain: how many do you have to sell to stop losing money? Set the price too low and every sale digs the hole deeper. Too high and nobody bites. Most owners land on a number that feels about right and find out later whether it was, after the fixed costs are already spent.

The break-even is knowable before you commit. It’s arithmetic that’s easy to fumble in a spreadsheet at the exact moment it matters most.

The numbers in, the break-even out

  1. Give it three figures, as flags or in a .env: your fixed cost for the period, the price per unit, and the variable cost per unit.
  2. It computes the contribution margin, price minus variable cost, which is what each sale actually puts toward covering the fixed costs.
  3. It divides fixed cost by that margin for break-even units, multiplies by price for break-even revenue, and can run the same math across a list of candidate prices.

What it tells you

  • Contribution margin per unit, the real amount each sale contributes once the variable cost is paid.
  • Break-even units and break-even revenue, the count and the sales dollars needed before a cent of profit appears.
  • A price-sensitivity table: hand it several candidate prices and it shows the break-even at each, so you can see what a lower price does to the volume you’d need.
  • If the margin is zero or negative, it says so plainly, reporting the break-even as unreachable rather than printing a nonsense figure. BREAKEVEN_REPORT.md and breakeven.json hold it all.

Who it’s for, and who it isn’t

Built for a small-business owner setting a price, launching a product, or sanity-checking one they already sell, who wants the break-even and how it moves with price. Anyone whose costs and price repeat per unit.

Not for you if you sell one-off custom jobs with no repeatable unit economics. Break-even per unit doesn’t map to a business where every job is priced from scratch. A blended break-even across many SKUs is on the roadmap, not in this version.

What it replaces, and what those do better

A spreadsheet where you re-derive the formula, or pricing by gut. Gut pricing is faster, and honestly the market sometimes sets the ceiling for you no matter what the math says.

What a feel-based price can’t tell you is the volume that makes it work, or how far you can cut before the numbers stop adding up. This runs the break-even the same way every time and lets you test prices side by side, for a flat fee, on your machine. Keep your read on the market. Let it check the arithmetic.

Your data, and where it stays

Every figure comes from flags or a local .env, and the only files written are the optional report, at 0600 permissions, where you say. No network call. What your costs and margins are is competitive information, and here it never leaves the terminal to become a break-even.

$29 a month, and your first analysis

Pass fixed cost, price, and variable cost on the command line, or set them in a .env, and run. The break-even prints on the spot, with a report if you set an output folder. Add a list of candidate prices to see the sensitivity table.

Flat monthly, cancel any day, and any saved reports stay on your disk.

Security and privacy

Handles a business’s pricing and cost figures (fixed cost, price, variable cost). Security is designed in.

Principles
Local-first. All inputs come from CLI flags or .env on disk and are never transmitted anywhere; nothing in this tool touches the network. Nothing is uploaded, no telemetry, no cloud dependency.
Non-destructive. No source documents (ledgers, cost sheets) are read or modified — inputs are typed configuration values only.
Least privilege. Writes only under OUTPUT_FOLDER, and only when the user opts in by setting it (or passing --out).

Protections implemented (v0.1.0)
Path-traversal defense — every output filename is sanitized (safeSegment) and every write is checked with assertWithinRoot(), so the report can’t be written outside OUTPUT_FOLDER.
Fail-fast config validation — clear errors for missing/invalid FIXED_COST/PRICE/VC/PRICES before any calculation runs. PRICE must be positive (it’s a divisor input); FIXED_COST/VC must be non-negative; PRICES entries (if supplied) must be positive.
Restrictive permissions — the generated report (BREAKEVEN_REPORT.md, breakeven.json) is written 0600, and only when OUTPUT_FOLDER is set.
Deterministic, pure calculationsrc/calc.ts has no I/O and no hidden state; the same inputs always produce the same output, making the math auditable and unit-testable. A zero-or-negative contribution margin is guarded explicitly (break-even reported as unreachable, never a misleading number).
Secrets discipline.env and generated Breakeven-Reports/ output are git-ignored; no client pricing data in the repo.

NOT financial advice
This tool produces a break-even and pricing estimate, not an audited financial statement or professional accounting advice. It computes contribution margin, break-even units, and break-even revenue directly from the figures provided — it does not validate those figures against a general ledger, does not account for step-fixed costs, taxes, or multi-product cost allocation. Always have a controller, CFO, or accountant review the inputs and results before using them for pricing or planning decisions.

Distribution / AV trust

Known limitations / roadmap
– Single-product, single-price-point break-even only — no built-in multi-SKU or blended-margin analysis (planned).
– No step-fixed cost modeling — assumes fixed cost is constant across the full break-even range.
– Assumes PRICE and VC are for the same unit definition; mismatched units will produce misleading contribution-margin figures.

Frequently asked questions about Break-Even & Pricing Analyzer

What does the Break-Even & Pricing Analyzer do, and how does it work?

The Break-Even & Pricing Analyzer answers a question a small-business owner asks all the time. How many do I need to sell before this price makes money? You give it three figures, your fixed cost, your variable cost per unit, and the price you are thinking about, and the tool works out where the line crosses from loss into profit. That crossing point is your break-even, shown both as a number of units and as an amount of revenue.

The flow is short on purpose. First you enter fixed cost, variable cost, and price. Then you run the analyzer. Then you read back your break-even units, your break-even revenue, and a set of price scenarios you can hold up against each other. There is no setup project and no training to sit through first. An owner who has been guessing at prices, or reusing last year’s numbers out of habit, can get a real answer in the few minutes it takes to gather the figures.

Those figures come straight from your own books, the sales slips, paid bills, and receipts that tell you what a unit truly costs and what you truly charge. The tool is only as honest as the numbers you feed it, so keeping clean records matters before you ever open it. The IRS is direct about how long a small business should hold those records. Its guidance on how long to keep business records spells out the periods, generally three years and longer in certain cases, so the cost and revenue history behind a pricing call is still on hand when you need to check your math.

What comes back is not a single lonely figure. The analyzer reports break-even in units and in revenue, so you can read it whichever way suits the business, per item sold or per dollar taken in. If it tells you that you must sell three hundred units to break even, and a normal month moves two hundred, the tool has just warned you the price is wrong before the end of the quarter proved it the hard way. Read as revenue, the same result tells a service business how many dollars of work it must book before the month clears its costs, which is often the more natural way to think when you do not sell in neat, countable units.

It is built for the owner who sets a price and then lies awake wondering how many they have to move to come out ahead. That is the whole audience. Not a finance team, not an analyst with a modeling background, just a person running a shop or a service who wants a plain answer they can act on. You can see how the Break-Even & Pricing Analyzer fits a working business on the product page, and the rest of the small-business lineup on the operators overview. The point of the tool is to turn a nervous guess into a number you can stand behind, built from figures you already keep, and it does that same job the same way on the first item and the hundredth.

How does the analyzer help me understand the revenue reported on a 1099-K?

Break-even math and the taxes you owe pull from the same place, the revenue your business actually takes in. The price you test in the Break-Even & Pricing Analyzer sets how much revenue each sale brings, and that revenue is also what shows up when a card processor or an online platform reports your sales to the government. If you take payment by card or through a marketplace, those payments get summarized on a Form 1099-K, so the revenue side of your pricing is the same figure the tax system is watching.

The IRS explains this on its page about understanding your Form 1099-K, which describes the form as a report of the payments you received for goods or services during the year. That is your gross sales, the top line the analyzer needs to find your break-even revenue. When you know the price and volume it takes to clear break-even, you also have a grounded sense of the gross receipts that will land on that 1099-K, which makes tax season less of a surprise.

This matters because the number on a 1099-K is gross, not profit. It reports what came in before any cost, and an owner who reads only that figure can badly misjudge how the business is doing. The Break-Even & Pricing Analyzer works the other side of the same coin. It shows how much of that gross revenue is eaten by fixed and variable cost before a dollar of profit appears. Reading the two together, the gross the 1099-K reports and the break-even the tool computes, gives a truer picture than either alone. A busy month can post a large 1099-K and still leave the owner short, and knowing the break-even is what explains why the deposit and the profit are not the same thing.

The tool does not file anything and it does not prepare your return. It is a pricing and break-even instrument, not tax software. What it does is help you understand the revenue you are aiming for, so the gross figure that eventually appears on a 1099-K is one you planned toward rather than one you discover after the fact. That planning is the honest value here, not any promise about filing. Used ahead of a price change, it also shows whether a planned discount would push your needed sales past what the season can realistically deliver.

Keeping the sales records behind those figures organized helps on both fronts. Clean records let you reconcile what a 1099-K reports against what you actually charged, and they feed accurate revenue into the analyzer. If you sell across more than one channel, seeing the combined break-even revenue in one place is useful precisely because your 1099-K forms may arrive from several processors. You can explore how the tool fits alongside the other back-office needs of a small operation on the small-business operators overview, and read the specifics on the product page. The steady idea is that the revenue you price toward and the revenue the 1099-K reports are the same money, so planning one helps you make sense of the other.

Where does my cost and pricing data live, and is it kept safe?

The Break-Even & Pricing Analyzer works from a small set of business figures, your fixed cost, your variable cost per unit, and the prices you are testing. It does not need your customers’ names, card numbers, or contact details to do its job. That is worth saying plainly, because the safest data is the data you never collected in the first place. The figures the tool holds are sensitive in a competitive sense, your true costs and margins, but they are not the personal information that carries the heaviest duty to protect.

That fits the plain advice the FTC gives small businesses in its guide, Protecting Personal Information: A Guide for Business. It sums up sound handling in one honest line, take stock, scale down, lock it, pitch it, and plan ahead. A pricing tool that asks only for cost and price figures already lives by the scale down step, because it is not gathering customer records it would then have to guard. There is simply less to lose.

Your cost and margin figures still deserve care. Margins are competitive information, the kind of thing you would not want a rival to read, so the account and the machine that hold your break-even work should sit behind a strong password, and turning on disk encryption is worth the small effort. Limiting who can open the numbers to the people who actually set prices follows the lock it step in the FTC guide. The analyzer helps by keeping the pricing work in one place, and it does not remove your ordinary duty to secure the device it runs on. Keeping a short list of who can reach the pricing account, and removing people when they move on, is that same lock it habit applied to your own team.

Because the Break-Even & Pricing Analyzer keeps the scenarios you ran, you also build an organized history of the pricing decisions you have tested over time. That record is useful when you revisit a price and want to remember what assumptions you made, and it stays with your own records rather than only in someone else’s system. Holding few copies of that history, in a place you control, is exactly the take stock and plan ahead thinking the FTC describes. If a laptop is ever lost, encryption is the difference between a stranger reading your margins and finding nothing usable at all.

The honest split is this. Software can keep your data in one controlled place and ask for less of it, and it cannot secure the laptop, the password, or the person for you. Those parts stay with the owner, guided by the same FTC steps. What the tool contributes is a design that needs only figures, not personal customer data, so the surface a stranger could ever reach is small to begin with. You can read more about how the tool handles your inputs on the product page. Keep the numbers in one place, ask for no more than the work requires, and lock the device they sit on, and your pricing data stays where it belongs.

How is the Break-Even & Pricing Analyzer different from a spreadsheet or a free calculator?

Most owners work out break-even in a spreadsheet or a free online calculator, and both have real limits. A free calculator gives you one number and forgets it the moment you close the tab. A spreadsheet you built yourself can do more, but the formulas are fragile, a stray edit breaks them quietly, and the file tends to get emailed around until nobody is sure which copy is the real one. The Break-Even & Pricing Analyzer is built to be the steady version of that math, with a price sensitivity table you do not have to wire up by hand.

The first difference is the sensitivity view. A basic calculator answers a single what-if. The analyzer shows a range of prices side by side, so you can see how the break-even point moves as you nudge the price up or down. That table is the part a free tool never gives you and the part a spreadsheet takes real effort to build correctly. Seeing the whole curve, rather than one point, is what turns a guess into a decision. Because every price sits in the same view, comparing three candidate prices takes a glance rather than three separate calculator runs.

The second difference is that your numbers stop wandering. A pricing spreadsheet full of your true costs is quietly sensitive, and the habit of mailing it between people and devices is how business data leaks. The idea of reducing that kind of risk sits at the center of the NIST Cybersecurity Framework, which helps organizations understand and reduce the risk to the information they hold. Keeping your pricing work inside one tool, rather than scattered spreadsheet copies, is a small move in the direction that framework points, fewer loose copies to track and protect.

The third difference is consistency over time. A calculator is a throwaway. The analyzer keeps the scenarios you ran, so your pricing history is one connected record instead of a folder of dated spreadsheets no one trusts. When you revisit a price six months later, the reasoning is still there, which a fresh calculator session can never offer. That continuity also helps when someone else takes over pricing, because the thinking behind past decisions did not leave with the spreadsheet’s original author.

There is an honest limit worth stating. If your needs are truly one-off, a free calculator will do the arithmetic, and this tool is not pretending that simple break-even math is impossible without it. What the Break-Even & Pricing Analyzer offers is the repeatable version, the sensitivity table, the kept history, and one place for the numbers instead of many. For an owner who prices more than once and wants to stop rebuilding the same spreadsheet, that is the trade. You can see where it fits among the other tools a small operator runs on the operators overview, and the details live on the product page. The short version is that a calculator gives you a number and a spreadsheet gives you a maintenance chore, while the tool gives you a repeatable answer you can trust.

How do the contribution margin and price sensitivity features actually help me set prices?

Beyond the single break-even number, the Break-Even & Pricing Analyzer gives you two things owners lean on most, the contribution margin per unit and the price sensitivity table. Contribution margin is what each sale adds toward covering fixed cost once its own variable cost is paid, the price minus the variable cost per unit. It is the cleanest measure of whether a product is pulling its weight, and the tool computes it for you so you are not doing the subtraction by hand for every item.

The price sensitivity table is the companion piece. It lays out how the break-even point shifts across a range of prices, so a small price change is no longer a leap of faith. You can see, in one view, that raising the price by a modest amount pulls your break-even volume down, or that a discount you were considering pushes it up further than felt comfortable. Reading contribution margin and the sensitivity table together is how an owner decides a price with eyes open. It also flags the prices where contribution margin turns thin, the point at which each sale barely covers its own variable cost and does little to pay down the fixed side.

Both depend on an accurate fixed cost, and for most small businesses labor is the largest piece of that. Wages are a cost you already have to document. The Department of Labor explains in its Fact Sheet 21 on FLSA recordkeeping that employers must preserve payroll records for at least three years and the records used to compute wages for two. Those same payroll figures are what you fold into fixed cost when you set up the analyzer, so a duty you already carry doubles as a clean input for honest break-even math.

Getting the cost inputs right is where the real value sits, because contribution margin and the sensitivity table are only as good as the fixed and variable numbers behind them. If payroll is guessed at or a variable cost is left out, the break-even the tool reports will be off in the same direction. The analyzer does not invent your costs. It takes the figures you supply and turns them into a per-unit margin and a price curve you can actually reason about. A missing shipping fee or an unlogged supply cost is the usual culprit behind a margin that looks too good, and the fix is in the input, not the tool.

Used well, the payoff is a pricing decision you can defend. You know what each unit contributes, you know how the break-even moves as the price changes, and you know the labor and other fixed costs behind it are grounded in records you keep anyway. That is a different footing than the gut feel most owners price on. You can walk through the enter-run-read flow and see the contribution margin and sensitivity outputs on the product page, or see how the Break-Even & Pricing Analyzer sits among the other back-office tools on the small-business operators overview. Feed it honest costs, and it hands back a price you set on purpose rather than by hope.
