Calculator
Know your revenue target
Enter your monthly fixed costs, the surplus you want and your variable cost share to see the monthly and daily net revenue your café needs, and how many sales a day that means.
Your targets
Fill in your month and select Calculate. Results appear only when every value is valid.
How the calculation works
- Break-even revenue = K ÷ (1 − v ÷ 100). Every euro of net revenue leaves (1 − v ÷ 100) to cover fixed costs.
- Target revenue = (K + T) ÷ (1 − v ÷ 100).
- Daily target = target revenue ÷ trading days.
- Sales per open day = daily target ÷ average sale. The exact value and the next whole number are shown; the whole number is a practical planning figure, not a prediction of demand.
At 100 % variable costs nothing is left to cover fixed costs, so no revenue reaches break-even in this model. Above 100 %, each sale loses money before fixed costs; that is outside what this planning model can describe.
What is not included
- VAT: all figures are net. The guest pays VAT on top, which you pass on.
- Income tax on your surplus.
- Seasonality: one month with its own trading days. Plan quiet and busy months separately.
- Capacity: whether your team, machine and seats can serve that many sales a day.
Worked example
Illustrative numbers: €6,000 fixed costs a month, a €1,000 surplus, variable costs of 30 % of revenue, 25 trading days and an average sale of €8.
| Break-even revenue | €6,000 ÷ 0.7 = €8,571.43 a month, €342.86 per trading day |
|---|---|
| Target revenue | €7,000 ÷ 0.7 = €10,000 a month |
| Daily target | €10,000 ÷ 25 = €400 |
| Sales per open day | €400 ÷ €8 = 50 |
Questions
What belongs in variable costs?
Costs that rise and fall with sales: ingredients, packaging, card and delivery-platform fees. If you know your cost of goods as a share of net revenue, start from that and add the fees.
Where do I put my own salary?
Either as a fixed cost or as part of the target surplus, but only once. Counting it twice makes the target look higher than it is.
Why show both 49.6 and 50 sales?
The exact value keeps the arithmetic transparent; you cannot make part of a sale, so the next whole number is the practical daily figure to plan with.
