Break-even volume
Calculate the units and sales needed to cover a fixed cost base, with an optional principal-and-interest payment.
Best for one consistently defined unit: a café ticket, paid session or job.
Business planning calculators
Answer one calculation question at a time, then put the result back into a full monthly plan.
Monthly loan payment
Calculate equal monthly payments, total interest and remaining principal for a fully amortizing fixed-rate loan.
Best for understanding a proposed amount, rate and term before adding fees or variable-rate scenarios.
Use a consistent input basis
Keep sales and costs on the same tax basis. Use a weighted average when transactions have different prices or cost mixes. Include the working owner’s compensation in the cost base if the business must fund it. Avoid adding the same labor or debt expense twice.
Simple calculators do not forecast liquidity
Break-even assumes a steady operating month. The payment calculator assumes the stated rate lasts for the full term and that scheduled payments begin one month after funding. Neither models an opening delay, changing inventory, balloon payment or revolving balance.
