Know your number before you set a price
Works out how many units, or how much revenue, you need to sell to cover your costs - from fixed costs, variable cost per unit and selling price. A break-even gauge shows exactly where your current or expected sales sit against that line, with an optional target-profit figure and a margin-of-safety check. Save any set of inputs as a named scenario to compare pricing options side by side.
The Calculator tab working out a sample product's break-even point, and the Scenarios tab comparing two saved pricing options.

Scenarios - saved pricing options compared side by side
Enter fixed costs, variable cost per unit and selling price, and the calculator works out exactly how many units - and how much revenue - you need to cover your costs, live as you type.
A single horizontal ruler from £0 to your current sales figure, with a marker at the break-even point and your current position shown against it - see how close you are at a glance.
Contribution per unit and contribution margin ratio are shown alongside the headline figures, so you can see how much of every sale actually goes towards covering fixed costs.
Set a target profit figure and get the units and revenue needed to hit it, not just to break even - useful when you're setting a sales goal rather than just covering costs.
Enter your current or expected units sold and see exactly how far above (or below) the break-even point you sit, both as a unit count and a percentage - a quick read on how much room you have before a loss.
Name and save a full set of inputs and results as a scenario, and build up a comparison table of pricing options, products or services side by side - no re-entering numbers to compare a second option.
GBP, EUR, USD, AUD, CAD and NZD symbols - break-even arithmetic doesn't vary by country, so you just pick the symbol that matches your own pricing.
Not construction-gated or industry-specific - works for any business pricing a physical product, a service, or a subscription, whatever the trade.
A light/dark toggle that remembers your choice, and "Load sample" fills in a realistic product costing so you can see the calculation before entering your own numbers.
Everything lives in local storage on your device - no account, no server, no internet connection required to use it day to day.
No forecasting, no invoicing, no full costing suite - just the one number that matters when you're setting a price: how much you need to sell to cover it.
Most small businesses either build a break-even formula in a spreadsheet from scratch each time, or pay for a full costing/pricing platform they don't need. Here's how a dedicated, focused calculator compares.

General comparison as of August 2026 - features and pricing vary by spreadsheet tool and by costing/pricing platform. Not sponsored by or affiliated with any spreadsheet or platform vendor.
It's a Windows desktop app. It is not yet available on the Microsoft Store - a Store listing is planned, but for now the app is built and ready ahead of submission.
It works out the point at which sales revenue exactly covers total costs - fixed costs plus variable costs - so profit is zero. Sell more than the break-even point and you're in profit; sell less and you're making a loss.
Fixed costs (rent, salaries, insurance - costs that don't change with sales volume), variable cost per unit (materials, packaging, direct labour per unit sold) and your selling price per unit. Target profit and current or expected units sold are optional.
The amount each unit sold contributes towards covering fixed costs, after variable costs - selling price minus variable cost per unit. Break-even units is fixed costs divided by contribution per unit.
How far your current or expected sales sit above the break-even point, in units and as a percentage - a quick read on how much sales could drop before you tip into a loss.
Save a set of inputs and results as a named scenario to compare pricing options, products or services side by side - useful when you're deciding between two prices or costings before committing to one.
Everything persists on your device between sessions - nothing is uploaded anywhere. The app works entirely offline with no server dependency, and data doesn't currently sync across multiple devices.
No - it's a calculator to help you work out a figure, not financial advice. Always check your own numbers and take professional advice for business decisions.
