Amortization Schedule

Overview & Methodology

The monthly payment is calculated using the standard amortization formula:

$$ M = P \cdot \frac{r(1+r)^n}{(1+r)^n - 1} $$

where:
P is the loan amount,
r is the monthly interest rate (annual rate ÷ 12 ÷ 100),
n is the total number of monthly payments (loan term in years × 12).

The tool simulates the loan payoff month by month, calculating for each payment the interest, the principal repaid, and the remaining balance.

Example

For example, for a €200,000 loan at a 4% annual rate over 30 years, the calculator computes a monthly payment of approximately €954.83 and generates a table showing the breakdown of each payment.

Frequently Asked Questions

How is the monthly payment calculated?

The monthly payment is computed using the formula:

$$ M = P \cdot \frac{r(1+r)^n}{(1+r)^n - 1} $$

where r is the monthly interest rate and n is the total number of payments.

What does the amortization schedule show?

It provides a breakdown of each monthly payment into its interest and principal components and shows the remaining balance over time.

Can I use this tool for refinancing calculations?

Yes. You can input different loan amounts, interest rates, or terms to compare various scenarios.
