How Weekly Payments Work
Divide by 4
Take your monthly payment and divide by 4 to get your weekly amount.
52 Payments = 13 Months
Because there are 52 weeks, you make the equivalent of 13 monthly payments per year.
Interest Compounds Less
More frequent payments reduce the balance faster, meaning less interest accrues over time.
What Is a Weekly Mortgage Payment?
A weekly mortgage payment splits your monthly payment into weekly instalments. The key benefit is not just convenience — because there are 52 weeks in a year but only 12 months, you effectively make the equivalent of 13 monthly payments per year instead of 12. This extra payment goes entirely toward reducing your principal, which can save thousands in interest and years off your mortgage term without significantly impacting your weekly budget.
How Weekly Payments Save You Money
By paying weekly instead of monthly, you make 52 payments per year. The annual total is higher than 12 monthly payments because 52 weeks equals 13 four-week periods. This extra month of payments each year accelerates your mortgage payoff.

Weekly Payment Formula
The weekly payment is your monthly payment multiplied by 12 (annual total) divided by 52 (weeks per year). However, the savings come from the fact that 52 weekly payments total more than 12 monthly payments. Annual weekly total = weekly × 52 = monthly × 12/52 × 52 = monthly × 12. But because payments are applied more frequently, interest accrues on a lower balance throughout the month, creating additional savings.
Tips & Best Practices

If your lender does not accept weekly payments, add 1/12th of your monthly payment as an overpayment each month for the same effect
- →
Align weekly payments with your pay cycle — if you are paid weekly, this matches your cash flow naturally
- →
The savings are largest on high-balance, long-term mortgages — the earlier you start, the more you save
