Launch Calculators
Five tools founders use before spending money. Results update as you type. Nothing you enter leaves your browser.
Startup cost calculator
Estimate what your launch costs in cash, including monthly runway.
| One-off costs | |
| Monthly costs | |
| Runway costs |
Formula: one-off + (monthly × runway months). Free static hosting and free tiers can bring monthly costs close to zero.
Break-even calculator
How many sales per month cover your fixed costs?
| Break-even revenue | |
| Contribution margin | |
| Sales needed per day |
Formula: fixed costs ÷ (price − variable cost). If you need many sales a day to break even, raise the price or cut costs.
Website revenue estimator
Combine display ads, affiliates and leads. Use conservative inputs.
| Display ads | |
| Affiliates | |
| Leads | |

RPM varies widely by topic, audience country and season. This is a planning estimate, not a guarantee of earnings.
