What does the Amortization Schedule do?
Amortization Schedule works out the full amortization schedule from the Loan Amount, Rate, and Years, following standard Finance conventions, and shows each step of the calculation.
- Inputs: Loan Amount, Rate, and Years.
- Output: the full amortization schedule.
- Method: the standard Finance formula, evaluated entirely in your browser.
Quick answer
Enter Loan Amount, Rate, and Years and amortization schedule shows the full amortization schedule immediately, with every step shown. Assumptions and limits are summarized below.
How does it work?
Amortization Schedule computes the full amortization schedule directly from your inputs — the Loan Amount, Rate, and Years feed the formula. Nothing is uploaded: the math runs locally in your browser and the result appears as you type.
What This Calculator Really Does
An amortization schedule is the complete life story of a level-payment loan: for every payment, how much is interest, how much reduces the principal, and what balance remains afterward. This calculator builds that table from your loan amount, rate and term using the standard annuity formula.
The pattern surprises first-time borrowers: early payments are mostly interest, and principal payoff accelerates only near the end of the term. Seeing the split month by month is the clearest way to understand why extra principal payments early in a loan save so much interest.
Everything runs locally in your browser — the schedule is computed on your device and never uploaded.
Quick answer: a $200,000 loan at 6% for 30 years amortizes to $1,199.10 per month, with about $1,000 of the first payment being interest alone.
The Formula, Explained Plainly
The level payment comes from the standard annuity formula:
PMT = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1)
- P — loan principal (e.g. 200,000).
- r — periodic rate: annual rate ÷ payments per year (6% monthly → 0.005).
- n — total number of payments (30 years × 12 = 360).
Each month after that: interest = balance × r; principal repaid = PMT − interest; new balance = old balance − principal repaid. Repeat until the balance reaches zero — that sequence is the amortization table.
How to Use It — In Order
- Enter the loan amount — the amount financed, not the purchase price.
- Enter the annual rate — the nominal contract rate.
- Set the term — years or total months.
- Read the payment — fixed for the whole term at a fixed rate.
- Scan the schedule — watch the interest share shrink and the principal share grow.
- Test extra payments — add principal and see months fall off the tail of the loan.
Worked Example, Verified by Hand
$200,000, 6% annual, 30 years, monthly payments:
- r = 0.06/12 = 0.005; n = 360.
- (1.005)³⁶⁰ ≈ 6.02258.
- PMT = 200,000 × 0.005 × 6.02258 / 5.02258 ≈ $1,199.10.
- Payment 1: interest = 200,000 × 0.005 = $1,000.00; principal = $199.10; balance ≈ $199,800.90.
- Total paid over 360 payments ≈ $431,676; total interest ≈ $231,676.
Add $100 of extra principal every month and the loan finishes years earlier — the schedule shows the exact saving.
Common Mistakes to Avoid
- Using the purchase price instead of the financed amount as principal.
- Forgetting escrow — taxes and insurance are not part of the amortized P&I payment.
- Comparing 15-year and 30-year loans on monthly payment alone — total interest differs dramatically.
- Assuming extra payments shorten the term automatically — some lenders lower the payment instead; state your preference.
- Ignoring origination fees — the schedule shows P&I, not closing costs (see the APR calculator).
Limitations
- Adjustable-rate loans re-amortize when the rate changes; this fixed schedule will not match those.
- Interest-only periods and balloon payments follow different schedules.
- Actual lender schedules can differ by a day's interest on the first period.
Expected Accuracy
The annuity formula is evaluated at full floating-point precision and each row follows the standard interest-first, principal-second convention. Figures match standard lender amortization to the cent for fixed-rate loans.
Privacy — Your Data Never Leaves This Device
The schedule is computed in your browser; no inputs are transmitted, stored, or tracked. Disconnect from the internet and it still works.

Frequently Asked Questions
What is an amortization schedule?
A table showing every payment of a loan split into interest and principal, with the remaining balance after each payment.
Why is my first payment mostly interest?
Interest each period equals balance × periodic rate. At the start the balance is at its maximum, so the interest share is largest; it shrinks as principal is repaid.
How much interest will I pay on a $200,000 30-year loan at 6%?
About $231,676 over the full term — more than the principal. The schedule shows the exact figure for your inputs.
Do extra payments go to principal?
If your lender applies them that way, yes — and they shorten the loan. The calculator shows the months saved for any extra amount.
Does amortization include taxes and insurance?
No — it covers principal and interest only; escrow items are added separately by your lender.
How do biweekly payments affect amortization?
Twenty-six half-payments equal thirteen full payments a year, so the loan amortizes faster and total interest falls.
What does the Amortization Schedule calculate?
Amortization Schedule turns the values you enter into a verified full amortization schedule — the formula, every intermediate step, and the assumptions sit beside the result instead of hidden behind it. Because the page doubles as documentation: Amortization Schedule puts the formula, a worked example, and the assumptions right beside the calculator.
How is the full amortization schedule calculated?
Amortization Schedule derives the full amortization schedule from the Loan Amount, Rate, and Years in a single pass, and the steps panel lists each operation. Amortization Schedule substitutes the Loan Amount, Rate, and Years into the formula, evaluates it in the order shown in the steps panel, and reports the output rounded for readability.
What do I need to use the Amortization Schedule?
The Loan Amount, Rate, and Years it asks for, or the page defaults if you just want to see the calculation work. Each input maps directly to the formula, and changing any one of them recalculates the full amortization schedule instantly.
What does the result from the Amortization Schedule mean?
The main number the amortization schedule returns is the full amortization schedule for your exact inputs, and the supporting figures and step list give it context. Very large or very small inputs can push the full amortization schedule beyond what is practically meaningful — sanity-check extreme values before relying on them.
When is the Amortization Schedule most useful?
Typical uses for Amortization Schedule include planning around a target figure, comparing scenarios side by side, and double-checking the full amortization schedule — anywhere the figure needs to be defensible rather than guessed. If the full amortization schedule looks wrong, read the steps panel before re-entering anything; it usually shows exactly where the number departed from expectation.
