# Amortization Calculator

This generates a complete amortization table for any fixed-rate loan. Add recurring extra payments at any frequency from weekly to yearly, plus optional fees and a one-time balloon or dated payment.

## How to use this amortization calculator

1. Enter the loan amount, interest rate, term, and first payment date.
2. If it applies, model additional payments at a weekly, monthly, quarterly, half-yearly, or yearly frequency.
3. Add extra fees if you have them (check “add to loan?” if they get financed into the principal), or a one-time payment as a balloon or on a specific date.
4. Click Calculate and switch between the Monthly breakdown and Yearly breakdown tables.

Want a payment-focused summary with the same inputs? Use the [Loan Calculator](https://shoutingnow.com/tools/loan-calculator/). Trying to figure out how long an existing balance takes to clear at your current payment? The [Loan Payoff Calculator](https://shoutingnow.com/tools/loan-payoff-calculator/) handles that.

## What is an amortization schedule?

An **amortization schedule** lists every payment period and breaks down how much goes to interest, how much retires principal, and what balance is left. Early payments are interest-heavy. Later payments put more toward principal in dollar terms even though the payment amount itself never changes.

### Reading the table

The payment column is your total outflow that month, regular payment plus any extra. Principal is the portion that reduces the balance, and interest is what borrowing on that opening balance actually costs you. Balance shows what you still owe once the payment clears.

The yearly view rolls each calendar year into one line and adds a final total row at the bottom.

### Extra payments and fees

Recurring extras get converted to a monthly equivalent based on how often you make them. $52 a week, for instance, works out to roughly $225.33 a month on top of your standard payment. Checking “add to loan?” on a fee rolls it straight into your starting principal.

## Examples and use cases

### Worked example

Take a **$200,000** mortgage at **6%** for **30 years**, or 360 months:

- Monthly payment ≈ $1,199
- First payment: about $1,000 interest, about $199 principal
- Total interest over 30 years ≈ $231,676

### Real-world use cases

- Refinance decision: A homeowner exports the yearly breakdown to see how much interest they would save refinancing from 7% down to 6%, closing costs and all.
- Extra payment strategy: Someone adds $200 a month to see how many years fall off a 30-year schedule and how much interest they dodge.
- Loan disclosure review: A borrower double-checks that the lender’s amortization table actually matches their principal, rate, and first payment date before closing.

## Frequently Asked Questions

### What is an amortization schedule?
It is a period-by-period table breaking each payment into interest and principal, with a running balance alongside. The [Amortization Calculator](https://shoutingnow.com/tools/amortization-calculator/) builds both monthly and yearly views for fixed-rate loans.

### How are extra payments applied in the schedule?
Recurring extras, whether weekly or yearly, get converted into a monthly amount and added each period after interest comes out of the regular payment. One-time balloon or dated payments instead knock a lump sum off the principal in whichever month you choose.

### Monthly vs yearly breakdown?
**Monthly** lists out every single payment period, while **yearly** rolls payment, principal, and interest up by calendar year and finishes with a total row.

### Why is early interest higher than later interest?
Because interest gets charged against the opening balance each month, so as principal comes down, the interest portion shrinks even though the payment itself stays flat.

### How is this different from the Loan Calculator?
They share the same underlying math. The [Loan Calculator](https://shoutingnow.com/tools/loan-calculator/) leans toward a payment summary, while this tool leans toward the full amortization table. Need payoff time on an existing balance instead? The [Loan Payoff Calculator](https://shoutingnow.com/tools/loan-payoff-calculator/) handles that.

### Is interest compounded monthly?
It is. The annual rate gets divided by 12 for monthly accrual, matching how most installment-loan calculators work, and you will see the effective annual percentage in the loan summary on related calculators.
