What are these calculators?

Our calculators turn everyday financial and date math into instant, accurate answers. Work out loan EMIs and total interest, add or remove GST, compute percentages, discounts, profit margins and markups, or calculate exact ages and date differences. Each one shows its working so you understand the result, not just the number.

Every calculation runs in your browser — your figures are never uploaded — and the tools are completely free with no sign-up. Use them to plan a loan before you borrow, price a product correctly, check a tax amount, or settle a date question in seconds.
