About Finance Tools

The finance calculators cover the money questions of everyday life: mortgage and loan payments, amortization schedules, credit card and debt payoff plans, compound and simple interest, investment returns, savings goals and retirement.

Salary and tax calculators turn an hourly rate or a yearly salary into take-home pay and estimate income tax, VAT and sales tax, while business calculators work out break-even points, profit margins, customer lifetime value and SaaS metrics. A currency converter, a tip and bill splitter and IBAN and card format references complete the set.

Every calculator is free, gives an instant result as you type and runs in your browser, on a computer, tablet or phone.
