How this loan calculator works

For loans with a fixed interest rate and equal monthly payments, we use the standard amortization formula:

Payment = P × [ r / (1 − (1 + r)⁻ⁿ ) ]

where:
P = loan amount (principal)
r = monthly interest rate (annual rate ÷ 12 ÷ 100)
n = total number of monthly payments (years × 12)

If the interest rate is 0%, the monthly payment is simply the principal divided by the number of months in the term.

What this calculator does and doesn’t include

✅ Fixed interest rate for the full term
✅ Equal monthly payments
❌ No taxes, insurance, or fees
❌ No early repayment, extra payments, or changing rates
