The EMI formula
EMI = P × r × (1+r)n ÷ [(1+r)n − 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the number of monthly installments. This calculates a fixed monthly payment that fully repays the loan, including interest, by the end of the tenure.
Useful for both personal and business loans
This works equally well for a personal loan, a car loan, or a business/equipment financing loan — such as financing a larger CCTV or smart home installation project through a bank facility rather than paying the full amount upfront.

Frequently asked questions
Equated Monthly Installment - a fixed monthly payment amount that repays a loan's principal and interest fully over an agreed period.
Not necessarily if it comes with a much longer tenure - a lower rate over more months can still result in more total interest paid than a slightly higher rate over a shorter period, so it's worth comparing both the EMI and total repayment figures.
The calculator simply divides the loan amount evenly across the number of months, since there's no interest component to add.
No, this calculates pure principal and interest based on the EMI formula - always add any processing fees, insurance or other charges your specific lender quotes separately.
