Understand your break-even result
Start with the calculator above. Then follow the example below, one step at a time.
What this calculator does
Break-even answers a useful starting question: how many sales would cover the costs in this plan? It turns a large monthly cost into a sales number you can compare with your time, space and likely customer demand.
It is not a forecast that those sales will happen. Use one product or one clearly defined service at a time, with a consistent price and cost per sale. A sale could mean one candle, one appointment or one standard order.
How it works
Fixed costs stay roughly the same within the sales level you are planning, such as monthly rent or a software subscription. Variable costs grow with each sale, such as ingredients, packaging or a per-sale payment fee.
Subtract the variable cost of one sale from its selling price. The amount left is called contribution because it contributes toward fixed costs. Divide fixed costs by contribution to find the required number of sales. Round up: part of a sale will not usually cover the full remaining bill.
The calculation assumes the same price and variable cost for each sale. It does not include an extra profit or owner-pay goal unless the relevant costs are already included. Keep those assumptions visible when using the result.
Break-even units = fixed costs ÷ (selling price per unit − variable cost per unit), rounded up to a whole unit.
Worked example
Example only. These are fictional business numbers, not recommended targets.
- Example: a fictional maker has $2,100 in fixed costs for one month. Each order sells for $84 and has $23 of variable costs.
- Each sale contributes $61 toward fixed costs: $84 − $23. This $61 is not all take-home profit because the monthly costs still need paying.
- Divide $2,100 by $61 to get about 34.43 orders. Round up to 35 whole orders.
- At 35 orders, sales are $2,940 and variable costs are $805. After $2,100 in fixed costs, $35 remains. At 34 orders, the business would still be $26 short.
- Try lowering the price while keeping costs the same. Watch the required sales rise. This shows why a promotion needs a cost check, not just a hoped-for increase in orders.
How to read your result
A lower break-even number may be easier to reach, but check your capacity and likely demand. If you can only make 25 orders in a month, a plan needing 35 deserves another look at price, cost or capacity.
If variable cost equals or exceeds price, each sale leaves nothing toward fixed costs or adds to the loss. There is no finite break-even number in that situation. More sales at the same terms will not close the gap. Check the inputs before assuming the business needs more customers.
Common mistakes
- Using monthly fixed costs but weekly sales capacity.
- Leaving payment fees or direct labor out of variable costs.
- Rounding down and calling the costs covered.
- Using an average price that does not match the mix of products you sell.
FAQ
Does break-even include profit?
It covers the fixed and variable costs entered. A separate profit goal needs another planning step; breaking even is not the same as meeting that goal.
Can a service business use this?
Yes, if you define one consistent service unit. Use matching prices and costs, such as one standard appointment rather than a mix of unrelated jobs.
What if my fixed costs are zero?
The modeled fixed-cost break-even can be zero if each sale has positive contribution. Still check that you have not missed costs needed to operate.
Why does a discount increase the sales needed?
A discount reduces what each sale contributes toward fixed costs if variable costs stay the same. More sales are then needed to cover the same bills.
Is the result a monthly target?
Only if your inputs cover a month. Use the result as a cost-covering checkpoint, then consider capacity, demand and any additional goals.
