Break-even calculator — how much you must sell to cover your costs
Enter your fixed monthly costs, your selling price and your cost per unit, and read the number of units and the monthly sales that bring you level.
Free to use. No sign-up.
- Profit on one unit
- 75.00 baht
- Units you must sell each month
- 400 units
- Monthly sales that break even
- 48,000.00 baht
Each unit leaves you 75.00 baht (62.5%) · fixed costs divided by that margin: 30,000 ÷ 75.00 = 400 units
Units are rounded up — half a sale does not pay the rent.
Runs entirely on your device. Nothing you type is sent anywhere.
This is arithmetic, not financial advice. The answer is only as good as the numbers you put in.
A worked example
A rice shop pays thirty thousand baht a month in rent and wages. A plate sells for a hundred and twenty baht and costs forty-five to make, so each plate leaves seventy-five. Thirty thousand divided by seventy-five is four hundred plates a month — about thirteen a day. Below that is a loss; above it is profit.
How to use it
Three fields. Fixed monthly costs are what you pay whether or not you sell anything — rent, standing wages, the minimum utility bill. Cost per unit is what is consumed each time you do sell: ingredients, packaging. The page subtracts the cost per unit from the price to get the profit on one unit, then divides the fixed costs by it. That is how many units you must sell each month, and it is also shown as a baht figure. If the price is not above the cost per unit there is no break-even at any volume, and the page says so plainly.

If you want to plan the months ahead, before you spend
Break-even tells you what one month has to look like. Start Business, the planning panel inside FlareApps, answers a different question: it lays out cash month by month for up to 36 months, with growth, churn and the cost of winning a customer folded in.
FlareApps has a free plan you can start on today; paid business plans are billed monthly or yearly, per business. Every real price is on the pricing page — no phone call needed.

- What is the difference between fixed costs and cost per unit?
- Fixed costs are the same whether you sell ten or a thousand — rent, standing wages. Cost per unit grows with what you sell: ingredients, packaging. Swapping the two throws the break-even figure out immediately.
- What if I sell several things at different prices?
- Use an average price and an average cost per ORDER rather than per item, and you get the number of orders a month you need. It is rougher, but it is easier to act on than working through every menu line.
- Does this include tax or loan interest?
- Not unless you put them into the fixed-costs field yourself. This page knows nothing about your tax position, your loan or your season.
