The numbers don't lie: mortgage overpayments can save you tens of thousands of dollars. But exactly how much depends on your loan, your strategy, and your consistency. Let's dive into real-world examples with actual numbers.
Before we dive into the details, here's what the data shows across thousands of mortgages:
Typical Savings: Adding $50-150/month to a $300k mortgage
Typical Savings: Adding $300-500+/month to a $300k mortgage
These are actual scenarios based on common mortgage situations. All calculations assume a 6.5% interest rate, which reflects current market conditions.
Scenario: $350,000 mortgage, 30-year term, 6.5% rate
Strategy: Extra $100/month (equivalent to daily coffee spending)
Total Interest Paid
Monthly Payment: $2,212
Payoff Time: 30 years
Total Interest Paid
Monthly Payment: $2,312
Payoff Time: 25.8 years
Real Impact: Sarah and Mike redirected their daily $3.30 coffee budget toward their mortgage. Result? They'll save enough to buy a luxury car and pay off their home 4+ years early.
Scenario: $280,000 mortgage, 30-year term, 6.5% rate

Scenario: $400,000 mortgage, 30-year term, 6.5% rate
Strategy: Bi-weekly payments (26 payments = 13 monthly payments per year)
Total Interest Paid
Monthly Payment: $2,528
Payoff Time: 30 years
Total Interest Paid
Bi-weekly Payment: $1,264
Payoff Time: 25.5 years
Real Impact: By simply splitting their monthly payment in half and paying bi-weekly, David and Lisa save over $121k with minimal lifestyle change.
Timing matters enormously with mortgage overpayments. Here's how the same $200/month extra payment performs depending on when you start:
| Start Time | Extra Payment | Interest Saved | Years Saved | ROI on Extra Payments |
|---|---|---|---|---|
| Year 1 | $200/month | $89,420 | 6.7 years | 624% |
| Year 5 | $200/month | $76,240 | 5.8 years | 531% |
| Year 10 | $200/month | $58,630 | 4.5 years | 390% |
| Year 15 | $200/month | $35,280 | 2.8 years | 221% |
| Year 20 | $200/month | $15,940 | 1.4 years | 87% |
*Based on $300,000 mortgage at 6.5% for 30 years
Think you need hundreds of dollars extra each month to make a difference? Think again. Here's what small, consistent overpayments can achieve:
| Extra Payment | Daily Cost | Interest Saved | Years Saved | Equivalent To |
|---|---|---|---|---|
| $25/month | $0.82 | $15,420 | 1.8 years | Skip one coffee per week |
| $50/month | $1.64 | $29,340 | 3.2 years | One streaming service |
| $75/month | $2.47 | $42,180 | 4.4 years | Two coffee drinks per week |
| $100/month | $3.28 | $54,020 | 5.4 years | Daily coffee habit |
"We used Aurebay's calculator to test different scenarios. Started with $75/month extra, then increased to $200 when we paid off our car loan. We're on track to save $98,000 in interest and pay off our home 8 years early!"

"As a new homeowner, I was overwhelmed by the 30-year timeline. Adding just $150/month (my old car payment) will save me $67,000 and 6.2 years. The calculator made it crystal clear!"
