How Mortgage Rates Over the Decades Impact Your Monthly Payment

When people think about buying a home, the first thing they often focus on is the price tag. But in reality, the mortgage interest rate is just as important. Even small shifts in rates can have a major impact on your monthly payment.

Let’s take a look at what a $400,000 home would cost across different decades, assuming a 10% down payment ($40,000) and a 30-year fixed-rate mortgage. That leaves a loan balance of $360,000.

The 1970s – Rates Around 8%

• Loan: $360,000

• Rate: 8%

• Monthly principal & interest: $2,642

The 1980s – Rates Hit Record Highs

In the early 1980s, mortgage rates reached 16–18%, making homes far less affordable.

• Loan: $360,000

• Rate: 16%

• Monthly payment: $4,821

What This Means for You

Looking back over the decades shows just how much interest rates influence affordability. The same $400,000 home could feel like a stretch—or a steal—depending on the year you bought it.

• For buyers: Remember that today’s rates aren’t permanent. Many homeowners refinance when rates drop.

• For sellers: Even with higher rates, demand remains steady, especially in desirable areas.
