Find the number you have to hit each month

Your break-even is the line between a stressful month and a calm one. Here is how to work out yours in one sitting.

Kerythos team · July 9, 2026

Ask most owners how much they need to make each month just to stay level, and you get a shrug. That shrug is expensive. Without a break-even number, every month feels like guesswork, and you cannot tell a genuinely good month from one that only looked busy.

The three pieces you need

Break-even is not accounting magic. It is three simple ingredients.

  1. Fixed costs. What leaves every month no matter what you sell: rent, subscriptions, insurance, your own wage. Add them up.
  2. Variable costs. What each sale costs you directly: materials, card fees, delivery. This rises and falls with your work.
  3. Your margin. For every dollar that comes in, what is left after the variable cost of earning it.

Break-even is simply the sales you need so that your margin covers all your fixed costs. Once your margin has paid off the fixed pile, everything after that is profit.

Work it out in one sitting

Take an hour and do this once:

  • List every fixed cost for a typical month and total it.
  • Look at a few recent jobs and work out what is left from each sale after its direct costs. That is your margin.
  • Divide your fixed costs by that margin rate. The result is the sales you need to break even.

That single figure is your line in the sand. Below it, the month costs you money. Above it, you are building something.

Break-even is not a limit. It is the moment every extra sale stops paying bills and starts paying you.

Turn the number into a rhythm

A monthly target is easier to steer when you break it into a weekly one. Divide by four and you have a number you can check against every Friday, while there is still time to act.

Keep an eye on the number that quietly moves it: your margin. If costs creep up and your prices do not, break-even rises even though nothing feels different, and you have to run faster to stand still.

Block one hour this week, run the three steps, and write your monthly number somewhere you will see it. Everything about pricing and planning gets clearer once you know it.
