Money maths, explained

EMI Calculator shows the monthly payment, total interest and a year-by-year schedule. GST Calculator adds or removes GST and splits it into CGST and SGST or IGST. SIP and FD calculators project returns with the compounding your bank uses.

Estimates, not advice

Results use standard formulas. Your bank or fund may round differently or charge fees, so treat the numbers as a guide and confirm with your lender or advisor.

Questions

How is EMI calculated?

EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r the monthly interest rate and n the number of months.

Does the GST calculator split CGST and SGST?

Yes. Choose same state for a CGST + SGST split, or other state for IGST.

Are SIP returns guaranteed?

No. SIP results assume a constant yearly return. Real mutual fund returns vary.
