Short answer
ProfitDrawer offers 4 free online calculators: a startup cost calculator, a price per job calculator for service businesses, a loan payoff calculator with extra payments, and a self-employed tax set-aside calculator. They are free with no sign-up, run in your browser, and nothing you type leaves your device. Each one shows its formula in a How it works section, and the results are estimates, not tax or financial advice.
| Calculator | What it works out |
|---|---|
| Startup cost calculator | Total one-time startup cost, monthly costs, cash left and months of runway with no sales. Starts from a cleaning, lawn care, vending machine or food truck example. |
| Price per job calculator | A suggested price per job from hours, materials, travel, your hourly pay, monthly overhead, jobs per month and profit margin, plus break-even jobs per month. |
| Loan payoff calculator | Months to pay off, payoff date and total interest, and how much interest and time an extra monthly payment saves. |
| Self-employed tax calculator | The amount to set aside each month, quarter or year at a share you choose, with the US self-employment tax part shown separately (profit x 92.35% x 15.3%). |
Notes:
- They need JavaScript switched on in your browser.
- Real loans and tax bills can differ (daily interest, fees, income tax, state tax), so treat results as a starting point.
- ProfitDrawer also has a free invoice template, available with a free account, and small business guides that explain the numbers.
