How Loan Repayment Works
Fixed-rate instalment loans are repaid through equal monthly payments. Each payment covers interest on the remaining balance and principal that reduces what you owe. Early payments are mostly interest; later payments are mostly principal. This is called an amortising loan.
The EMI Formula
EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total monthly payments (years × 12)
Example: $15,000 at 8% APR over 3 years → EMI = $470/month, total interest = $1,921.
Loan Cost Comparison
| $20,000 at 7% APR | Monthly Payment | Total Interest |
|---|---|---|
| 2-year term | $895 | $1,485 |
| 3-year term | $618 | $2,238 |
| 5-year term | $396 | $3,761 |
| 7-year term | $301 | $5,303 |
Tips for Reducing Loan Cost
- Make extra payments: Even small extra payments cut years off your loan.
- Refinance when rates drop: A lower rate on the same balance saves thousands.
- Compare APR, not just monthly payments: A longer term often costs more overall.
- Avoid payment holidays: Interest accrues during breaks, increasing your balance.

Frequently Asked Questions
What does EMI stand for?
EMI stands for Equated Monthly Instalment — the fixed monthly payment made to repay a loan over a set period. Each payment includes both principal repayment and interest charges.
How is EMI calculated?
EMI = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P = loan principal, r = monthly interest rate (annual rate ÷ 12), n = total months. Our calculator applies this formula automatically.
Does a longer loan term mean lower EMI?
Yes, a longer term means lower monthly EMI but significantly higher total interest paid. A $25,000 loan at 8.5% for 3 years has EMI of ~$789 with ~$3,400 total interest. The same loan over 7 years has EMI of ~$390 but ~$7,700 total interest.
What is an amortization schedule?
An amortization schedule shows the month-by-month breakdown of each loan payment: how much goes to principal, how much to interest, and what the remaining balance is. It shows how early payments are mostly interest, while later payments are mostly principal.
Can I pay off a loan early?
Most loans allow early repayment, though some charge a prepayment penalty. Early repayment saves on interest. Even making one extra payment per year can significantly reduce total interest paid and shorten the loan term.
