Calculators that run in your browser. No account, no invented bank rates, no gold prices until a live source exists.

EMI Calculator

Estimate monthly EMI, total interest, and overall payout for a home, car, or personal loan.

SIP Calculator

Project how a monthly SIP can grow using a constant expected annual return, with an optional yearly step-up in the instalment. The projection is not guaranteed.

GST Calculator

Add GST to a price, or back out the tax from an inclusive amount. Since 22 September 2025 most goods and services are taxed at 5% or 18%, with 40% for a select few — other rates exist.

Percentage Calculator

Find a percentage of a number, reverse a percentage, or measure percentage increase and decrease.

Salary Calculator

Estimate monthly in-hand pay from CTC or gross salary. Indian payroll has no single formula — this is an estimate.

Gold Jewellery Calculator

Price a piece of gold jewellery from a gold rate you enter: weight, purity, making charges and GST shown separately. Janooji does not provide a live gold rate.

Age Calculator

Exact age in years, months, and days from a date of birth, using calendar dates — not 365-day years.

CGPA Calculator

Convert CGPA to percentage, or percentage to CGPA, using a multiplier you choose. There is no single Indian conversion rule.

Income Tax Calculator

Estimate income tax for a selected Indian tax year under the new or old regime. This is not a filed return.

FD Calculator

Fixed-deposit maturity from the compound-interest formula. The rate you enter is not a bank offer.

PPF Calculator

Estimate PPF corpus using notified contribution limits and the Scheme’s monthly lowest-balance interest rule.

RD Calculator

Recurring deposit maturity from a monthly deposit, interest rate and tenure. The rate you enter is not a bank offer.

Home Loan Prepayment Calculator

See how much interest a part-prepayment saves on a home loan and how much sooner the loan ends, with the original and revised repayment compared.
