Interest Rate Calculator answers
It helps you find the rate implied by a loan or investment when you already know the principal, tenure and payment or return. Useful when a lender quotes EMI but not the effective annual rate clearly.
EMI, mortgage payment, and installment are names for the same monthly payment. The formula is the same in the United States, Canada, the UK, Australia, Germany, and India. A lender can still add fees. Use the country menu to change the currency.
A worked check
A 100,000 loan at 8% a year for 5 years has a monthly payment of about 2,028. Total paid is about 121,658, so interest is about 21,658. Stretch the same loan to 10 years and the monthly payment falls, while total interest rises. The currency symbol follows the country you select. The payment formula does not.
