15-Year vs 30-Year Mortgage Comparison

Comparing 15-year and 30-year mortgages involves several key factors:

Monthly payments: Higher for 15-year loans due to shorter repayment period
Total interest paid: Generally lower for 15-year loans
Total cost of the loan: Often lower for 15-year loans
Cash flow: 15-year loans free up more cash flow in the early years

The table below shows a typical comparison for a $300,000 loan at 6% interest rate:

Term	Monthly Payment	Total Interest Paid	Total Cost
15-year	$2,500	$120,000	$420,000
30-year	$1,800	$210,000	$510,000

Worked Examples

Example 1: $250,000 Loan at 5% Interest

For a $250,000 loan with a 5% interest rate:

15-year mortgage: Monthly payment $2,000, total interest $60,000
30-year mortgage: Monthly payment $1,400, total interest $105,000

In this case, the 15-year mortgage saves you $45,000 in interest over the life of the loan.

Example 2: $400,000 Loan at 7% Interest

For a $400,000 loan with a 7% interest rate:

15-year mortgage: Monthly payment $3,200, total interest $168,000
30-year mortgage: Monthly payment $2,400, total interest $288,000

Here, the 15-year mortgage saves you $120,000 in interest over the life of the loan.

Frequently Asked Questions

Which mortgage term saves more money?

A 15-year mortgage typically saves more money in total interest paid compared to a 30-year mortgage, especially for larger loans or higher interest rates. However, the higher monthly payments of a 15-year mortgage may not be suitable for everyone.

Can I refinance from a 15-year to a 30-year mortgage?

Yes, you can refinance from a 15-year to a 30-year mortgage, but you'll typically need good credit and may face closing costs. The new mortgage will have a lower monthly payment but higher total interest over time.

Are there any penalties for paying off a 15-year mortgage early?

Most 15-year mortgages have prepayment penalties, which means you'll pay fees if you pay off the loan before the term ends. Check your loan agreement for specific details about prepayment penalties.

Which mortgage term is better for cash flow?

A 15-year mortgage typically provides better cash flow in the early years because you'll be paying off the loan faster and have more money available for other expenses. However, the higher monthly payments may be difficult to manage for some borrowers.
