What is Loan Amortization?
Amortization Definition
Loan amortization is the process of paying off a loan through regular, scheduled payments over time. Each payment includes both principal and interest components, with the proportion changing throughout the loan term. This amortization calculator shows exactly how each payment is distributed.
Amortization Formula:
M = P × [r(1+r)ⁿ] / [(1+r)ⁿ-1]
Where M=Monthly Payment, P=Principal, r=Monthly Rate, n=Number of Payments
How Amortization Works
During loan amortization, early payments consist mostly of interest, while later payments focus more on principal reduction. Our amortization calculator provides a complete payment schedule showing this transition over the entire loan term.
- •Early Payments: Higher interest portion, lower principal reduction
- •Middle Payments: Balanced interest and principal portions
- •Late Payments: Lower interest, higher principal reduction
- •Final Payment: Completes loan payoff with minimal interest

Frequently Asked Questions (FAQ)
What is the difference between amortization and depreciation?
Amortization refers to spreading loan payments over time, while depreciation is allocating asset costs over its useful life. Amortization deals with loans and intangible assets, while depreciation applies to tangible assets like equipment and buildings.
How does extra principal payment affect amortization?
Extra principal payments reduce the loan balance faster, decreasing future interest charges and shortening the loan term. Our amortization calculator shows how additional payments can save thousands in interest and help you become debt-free sooner.
What is a fully amortizing loan?
A fully amortizing loan is completely paid off at the end of the term through regular scheduled payments. Each payment is calculated to ensure the loan balance reaches zero exactly on the final payment date, with no balloon payment required.
How is monthly payment calculated in amortization?
Monthly payment is calculated using the loan amount, interest rate, and loan term. The formula ensures each payment is the same amount while the proportion of interest vs principal changes over time. Early payments have more interest, later payments have more principal.
What types of loans use amortization?
Common amortizing loans include mortgages, auto loans, personal loans, and student loans. These loans have fixed payment schedules that fully pay off the loan over the specified term, unlike interest-only loans or credit cards.
Can amortization help with tax planning?
Yes, amortization schedules help track deductible interest payments for tax purposes. For mortgages and business loans, interest portions of payments may be tax-deductible. The amortization calculator shows exactly how much interest you pay each year.
What is negative amortization?
Negative amortization occurs when monthly payments are insufficient to cover all accrued interest, causing the loan balance to increase instead of decrease. This happens with certain adjustable-rate mortgages or payment-option loans where minimum payments don't cover full interest.
How does amortization affect home equity?
As you make amortizing payments, your principal reduction builds home equity while property value appreciation can increase it further. The amortization schedule shows exactly how quickly you're building equity through principal payments.

Why Calculate Amortization?
Understanding amortization helps you make informed borrowing decisions, plan payments, and see how much interest you'll pay over the loan's life.

Understanding Your Amortization Results
Payment Breakdown
Principal: Amount that reduces your loan balance
Interest: Cost of borrowing money
Total Payment: Combined principal and interest
Remaining Balance: Loan amount after each payment
Interest vs Principal
Early payments have higher interest portions, later payments focus more on principal reduction. This is why you build equity faster in later years of the loan.
