This tool helps you calculate detailed monthly payments and total interest for a 20-year loan.
How to Use the Loan Calculator
To use this loan calculator, enter the loan amount, the annual interest rate, and any extra monthly payment you would like to make.
- Loan Amount: The total amount of the loan.
- Annual Interest Rate: The annual interest rate on the loan in percentage.
- Loan Term: The duration of the loan, which is fixed at 20 years.
- Extra Monthly Payment (optional): Any additional amount you plan to pay each month towards the loan principal.
Click the “Calculate” button to see the results. The calculator will display a table showing the month-by-month breakdown of your payments, including the portion of each payment that goes towards the principal, the interest, and the remaining loan balance.
How the Calculator Works
The loan calculator uses the following formula to calculate the fixed monthly payment:
Monthly Payment = [P * r * (1 + r)^n] / [(1 + r)^n - 1]
Where:
- P: The loan amount.
- r: The monthly interest rate (annual interest rate divided by 12).
- n: The total number of monthly payments (loan term in years multiplied by 12).
The calculator then iterates through each month to break down the total monthly payment into the principal and interest, and subtracts any extra payments from the remaining balance. This results in a detailed month-by-month amortization schedule until the loan is fully paid off.
Limitations
While this calculator provides a detailed breakdown of the loan payments, it has the following limitations:
- The interest rate is fixed throughout the loan term.
- It does not account for fees or taxes that might be associated with the loan.
- Extra payments are assumed to be constant each month.
For a more precise calculation, consult your lender for the exact terms and conditions of your loan.
