Free Financial Calculators for Everyday Use

The calculators are intended for general information and everyday calculations. They can help you understand numbers more easily, but they should not replace the official figures supplied by a bank, employer, financial institution, merchant or other relevant provider.

Understanding the Calculations
Knowing what each calculator measures can make the results easier to understand and compare.
Loan calculations
A loan repayment calculation estimates how much may be required periodically to repay a specified principal and interest rate over a chosen period. The actual repayment from a lender may also include fees, insurance or other charges.
Simple interest
Simple interest is calculated from the original principal, the interest rate and the amount of time. It does not use previously accumulated interest as part of the principal for subsequent calculations.
Annual salary
The salary calculator multiplies the monthly salary by 12 to produce an estimated annual gross figure. It does not calculate taxes, pension contributions or other payroll deductions.
Currency conversion
Currency conversion depends on the exchange rate being used. Rates can change frequently and the rate available from a bank, bureau, payment provider or other financial service may differ from a publicly available reference rate.
Tip calculation
The tip calculator applies the percentage you enter to the bill amount and adds the calculated tip to the original bill.
