Understanding Loan Amortization
Loan amortization is the process of paying off a loan over time through regular payments. Each payment covers both interest and principal, with the interest portion decreasing and the principal portion increasing over time.
The Amortization Formula
The standard formula for calculating a fixed monthly payment is:
Payment = P × (r(1 + r)n) / ((1 + r)n - 1)- P = Principal (loan amount)
- r = Monthly interest rate (annual rate / 12 / 100)
- n = Number of payments (months)
Example: For a $10,000 loan at 5% annual interest over 3 years (36 months):
- P = $10,000
- r = 0.05 / 12 = 0.004167
- n = 36
Plug into the formula to get your monthly payment.
How Payments Are Split
Early payments mostly cover interest; later payments cover more principal. This is why your loan balance drops slowly at first, then faster near the end.
