Compare 30-year and 15-year mortgages to determine which option saves you more money on interest over time. This calculator helps you understand the financial implications of choosing a longer or shorter mortgage term.
How to Use This Calculator
To compare 30-year and 15-year mortgages, follow these steps:
- Enter the loan amount you're considering.
- Input the current interest rate for both loan terms.
- Click "Calculate" to see the monthly payments and total interest paid for each term.
- Compare the results to determine which option is more cost-effective for your situation.
The calculator will display the monthly payment, total interest paid, and total amount paid for both loan terms, allowing you to make an informed decision.
Formula Used
The calculator uses the standard mortgage payment formula to calculate monthly payments and total interest paid:
Monthly Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in months)
The total interest paid is calculated by subtracting the principal loan amount from the total amount paid over the life of the loan.
Worked Example
Let's compare a $200,000 mortgage with a 4% annual interest rate:
| Term | Monthly Payment | Total Interest Paid | Total Amount Paid |
|---|---|---|---|
| 30-Year | $1,073.64 | $183,192.00 | $383,192.00 |
| 15-Year | $1,483.79 | $103,068.00 | $303,068.00 |
In this example, the 15-year mortgage saves you $80,124 in interest over the life of the loan, but requires higher monthly payments.
