Finance Calculators

Work out percentages in seconds — find X% of a number, see what percent one value is of another, reverse a percentage, measure the change between two values, or add and subtract a percent. The result updates live as you type.

Find the final price after a discount and see exactly how much you save. Optionally add sales tax — applied to the discounted price, the way it works at checkout. Works for any store, any currency.

Split the bill and work out the tip in one step. Enter the bill, choose a tip percentage and set how many people are paying. See the tip amount, the total and exactly what each person owes.

Add tax to a net price or extract it from a gross price — works for sales tax, VAT and GST at any rate. See the net, tax and gross amounts side by side so you can verify the calculation instantly.

Convert between hourly, daily, weekly, monthly and annual pay in one place. Set your actual hours and days per week to get precise equivalents — no need to assume the standard 40-hour week.

Measure the return on any investment or project. Two modes: enter an initial and final amount for a simple ROI, or enter revenue and cost for a business return. See the profit, margin and ROI percentage together.

Project the future value of regular monthly contributions. Enter the amount, expected return and years to see the total invested, the gains earned and what share of the final amount came from returns.

Find the exact number of days, weeks, months and years between any two dates. Pick the start and end dates — or leave the end empty to use today. Handles past and future dates, including leap years.

Estimate income tax with custom brackets that work for any country. Enter gross income, deductions, base and higher rates to see total tax, effective rate, marginal rate and take-home pay.

Find out how much you need to save each month to reach a financial goal. Enter the target amount, any starting deposit and the years you have — get the monthly contribution, total invested and expected gains.

See the maximum loan you can qualify for based on income, existing debts and the lender's debt-to-income limit. Enter monthly income and current payments to get your borrowing ceiling and available monthly payment.

Compare the long-term financial outcome of buying a home versus renting and investing the difference. Enter your numbers and see which option leaves you with more equity or a bigger portfolio after the comparison period.

Calculate the maturity value and interest earned on a fixed deposit or term deposit. Choose any compounding frequency — monthly, quarterly, semiannually, annually or daily — and see the effective annual rate.
