How Mortgage Payment Frequency Affects What You Pay Over Time

You’ve probably heard the saying that there are two certainties in life: death and taxes.
When it comes to your mortgage, there’s really just one certainty—you’ll repay what you borrow, plus interest.

What is flexible, though, is how often you make your mortgage payments. And that choice can have a meaningful impact on how quickly you pay down your mortgage and how much interest you pay over time.

The Six Mortgage Payment Frequencies

Most lenders offer the following payment options:

• Monthly – 12 payments per year
• Semi-monthly – 24 payments per year
• Bi-weekly – 26 payments per year
• Weekly – 52 payments per year
• Accelerated bi-weekly – 26 payments per year
• Accelerated weekly – 52 payments per year

Standard Payment Frequencies

The first four options are designed to align with how you get paid.

For example:

• Paid monthly? Monthly mortgage payments may make sense.
• Paid every two weeks? Bi-weekly payments can align nicely with your cash flow.

With these standard options, regardless of how often you pay, the total amount paid over the year is the same—it’s simply divided into more frequent payments.

What Makes “Accelerated” Payments Different

Accelerated payments work differently—and this is where the real savings happen.

With accelerated bi-weekly or accelerated weekly payments, you’re paying a slightly higher amount each time. That extra money goes directly toward reducing your mortgage principal, which lowers the interest you’ll pay over the life of the mortgage.

A Simple Example

Let’s assume a $1,000 monthly mortgage payment:

• Monthly:
  $1,000 once per month = $12,000 per year
• Semi-monthly:
  $500 twice per month = $12,000 per year
• Bi-weekly:
  $1,000 × 12 ÷ 26 = $461.54 every two weeks = $12,000 per year
• Accelerated bi-weekly:
  $1,000 ÷ 2 = $500 every two weeks = $13,000 per year

With accelerated bi-weekly payments, you effectively make two extra payments per year without having to think about it. Those extra payments reduce your principal faster, which lowers interest costs over time.

Accelerated weekly payments work the same way—you just make smaller payments more frequently.

Why This Matters Long Term

While it’s difficult to calculate exact savings due to variables like interest rates, terms, and amortization changes, maintaining an accelerated payment schedule over the life of your mortgage can reduce your amortization by up to three years and save a significant amount of interest.

The Bottom Line

Accelerated payments are a simple, automatic way to lower your overall cost of borrowing—without needing to make lump-sum payments or drastically change your budget.
