How Our Amortization Calculator Works
An amortization calculator helps you understand how your mortgage payments are structured over time. Unlike simple loan calculators, it shows exactly how much of each payment goes toward principal vs interest, and how your balance decreases over the life of your loan.
Understanding Amortization
Amortization is the process of spreading out a loan into a series of fixed payments over time. Each payment consists of two parts:
- Principal – The original loan amount you’re repaying
- Interest – The cost of borrowing the money
In the early years of your mortgage, a larger portion of your payment goes toward interest. As you continue making payments, the balance shifts so that more goes toward the principal.
Key Inputs Explained
Our calculator uses several key inputs to determine your payment schedule:
Mortgage Amount: The total purchase price of the property you’re financing. For example: $350,000 for a typical single-family home.
Down Payment: The upfront payment you make toward the property. A larger down payment reduces your loan amount and can often get you better interest rates. Example: $70,000 (20% of $350,000).
Interest Rate: Enter the annual rate quoted by your lender. Actual rates vary by lender, loan type, credit profile, location and market conditions, so use a current offer rather than a generic rate range.
Amortization Term: The total length of time over which you’ll repay the loan. The most common terms are 15 or 30 years.
Payment Period: Choose how often payments are made: monthly, bi-weekly or weekly. More frequent payments can change the total amount paid each year and may shorten the payoff period. Actual results depend on the payment amount and when your lender applies each payment.
Interpreting Your Results
After entering your information, the calculator provides:
Payment Amount: Your regular payment amount based on the inputs provided.
Total Interest: The total amount of interest you’ll pay over the life of the loan. This helps you understand the true cost of borrowing.
Amortization Schedule: A year-by-year breakdown showing how your payments are applied to principal and interest, and how your loan balance decreases over time.
Visual Breakdown: A graphical representation showing what percentage of your total payment goes toward principal vs interest.
Smart Mortgage Tips
Make Extra Payments
If your lender allows extra payments, applying them to principal may reduce total interest and shorten the repayment period. Check for prepayment rules or fees, and ask the lender how extra payments are applied.
Consider Bi-weekly Payments
By making half-payments every two weeks, you’ll make 26 payments per year (equivalent to 13 monthly payments), reducing your loan term.
Refinance When Rates Drop
If interest rates drop significantly, refinancing could save you thousands over the life of your loan. Use our calculator to compare scenarios.
Check How Payment Dates Affect Interest
This may matter for loans that calculate interest daily and credit payments when received. For fixed-payment amortization schedules, the effect depends on your lender’s interest method and payment-posting rules, so confirm these details before changing your payment date.
Review Your Amortization Schedule
Check your schedule annually to see your progress and identify opportunities to make extra payments where they’ll have the most impact.
Lump-Sum Payments
Apply windfalls like tax refunds or bonuses directly to your principal to significantly reduce your loan balance and total interest.
Amortization FAQs
An amortization schedule is a complete table of periodic loan payments showing the amount of principal and the amount of interest that comprise each payment until the loan is paid off at the end of its term. Each calculation done by the calculator will also display the balance remaining after each payment has been made.
In the early years of your loan, your outstanding principal balance is highest, and interest is calculated as a percentage of that balance. As you make payments and reduce the principal, the interest portion of each payment decreases while the principal portion increases. This is why more interest is paid at the beginning of the loan term.
Extra payments applied to principal can reduce the balance on which future interest is calculated and may shorten the repayment period. This calculator does not include an extra-payment input, so it cannot estimate the exact savings from additional payments. Check your lender’s prepayment rules and request an updated amortization schedule to see their effect.
The loan term is the length of time you have to repay the loan, while the amortization period is the length of time it takes to pay off the entire mortgage if you make only the scheduled payments. For most fixed-rate mortgages, the loan term and amortization period are the same. However, for adjustable-rate mortgages, the amortization period might be longer than the initial fixed-rate term.
It’s a good practice to review your amortization schedule at least once a year. This helps you understand how much progress you’re making on paying down your principal and how much interest you’re paying. You can also use this review to identify opportunities to make extra payments or consider refinancing if interest rates have dropped significantly.
