21 free tools, no sign-up, files never uploaded.

Money and everyday-math calculators that show their working: loan EMIs and eligibility, mortgages, SIP and compound interest, GST, VAT and sales tax, percentages, discounts, tips, fuel costs, inflation, GPA and CGPA, ages and date differences.

Each calculator states the exact formula it uses so you can verify the result, and each updates instantly as you type. Financial results are standard mathematical estimates - always confirm exact figures with your lender or institution.
