About Percentage & Finance Calculator

The loan figures use the standard amortising formula, where the monthly payment stays level while the split between interest and principal shifts across the term. That is why total interest, rather than the monthly number, is the figure worth comparing between two offers.

Estimate the monthly EMI, the total interest and the total amount payable on a loan from its principal, rate and term. All the amortisation maths runs privately on your device.

Work out percentages and percentage change, sale discounts and final prices, tip splits per person, and monthly loan or EMI payments with total interest — all in one place. It covers the everyday money maths that comes up while shopping, dining out, budgeting and comparing loans.

Switch between modes to answer 'what is X% of Y', 'how much do I save', 'what is each person's share' or 'what will this loan cost'. Percentage change is the one to double-check: 40 rising to 50 is a 25% increase, while 50 falling back to 40 is a 20% decrease.

Frequently asked questions

What exactly is an EMI?

An Equated Monthly Instalment — a fixed payment that covers both interest and principal, so the loan clears exactly at the end of the term. The amount stays the same each month, but its composition shifts: early payments are mostly interest, later ones mostly principal.

Why do I pay so much interest in the early years?

Interest is charged on the outstanding balance, which is at its largest at the start. That is also why overpaying early has an outsized effect — every extra pound reduces the balance that all future interest is calculated on.

Is the rate I enter annual or monthly?

Enter the annual rate as quoted; it is converted to a monthly rate internally. Be aware that an advertised APR may bundle in fees, so an EMI calculated from the headline rate can differ slightly from a lender's own quote.
