The Mortgage Marathon: Timing Extra Payments Right
Making extra payments on your mortgage is like running a marathon. Most people approach it the wrong way — they either sprint too hard too soon or don’t try at all. They rubberband between bursts of motivation and long periods of doing nothing. But there’s a smarter rhythm to paying off your mortgage — one that can save you tens of thousands of dollars and years off your loan. It’s all about timing, mindset, and consistency. Paying off your mortgage isn’t a sprint — it’s a marathon. And just like a race, knowing when to push harder makes all the difference.
Thirty years is a long time, but small, strategic moves early and late in the process can create massive savings. A marathon is just over 26 miles, so we’ll use that as our comparison — 30 miles, 30 years. There are three key phases in any long run: the beginning, the long middle, and the final stretch. You’ll want to start strong to build momentum, coast in the middle to preserve energy, and finish fast when you’re close to the end.
This timing matters because mortgage interest is front-loaded — meaning you pay mostly interest in the early years. The faster you chip away at your principal in that stage, the more you’ll save in interest overall.
Phase One: The Early Sprint (Years 1–5)
This is where your effort pays off the most. Every extra dollar you put toward your principal during these first few years attacks the balance while interest charges are at their highest.
Let’s use a real example:
Imagine you have a $300,000 mortgage at 6% interest for 30 years. Your monthly payment (principal + interest) would be around $1,799. If you made just one extra payment per year, you’d pay off your loan nearly 4 years early and save about $45,000 in interest.
If you could add $200 extra per month starting in year one, you’d finish the loan almost six years early, saving over $70,000.
That’s the power of the early sprint — small, consistent effort when interest is working against you. Most homeowners are most motivated in these first few years, so channel that excitement into your financial strategy.
Phase Two: The Coasting Years (Middle of the Loan)
This is where you settle into your rhythm. You’ve gained a lot of ground already — your principal is smaller, you’re building equity, and you’ve likely knocked out PMI (private mortgage insurance).
At this stage, it’s fine to slow your pace. You might be shifting focus to investing, retirement savings, or other financial goals. Even if you pause extra payments for a while, the head start you built early keeps working in your favor.
Think of it like mile 13 of your marathon — you’ve already run half, and the finish line feels distant, but your endurance matters more than speed. Keep your regular payments consistent, and if you can throw in the occasional small extra, do it — but the main goal here is to maintain balance and financial flexibility.
Phase Three: The Final Sprint (Last 5 Years)
Now the finish line is in sight. You’ve made it through the long middle miles, and this is where the emotion and math align beautifully. Every dollar of extra payment now goes directly toward principal — and the payoff becomes very real.
Let’s go back to our $300,000 example. If you have five years left and owe around $80,000, paying an extra $500 per month would help you finish nearly two years early — and you’d save another $8,000–$10,000 in interest.
At this point, the biggest motivation isn’t just the math — it’s the feeling. Imagine sending in your final payment, owning your home free and clear, and freeing up nearly $1,800 a month in cash flow. That’s not just financial freedom; it’s peace of mind.
Common Pitfalls to Avoid
It’s tempting to dive straight into extra payments, but there are a few things to watch for:
Don’t make extra payments if you still have high-interest debt like credit cards — that money should go there first. You’ll get a much higher return by eliminating those balances before attacking your mortgage.
Always ensure your lender applies your extra payment to the principal, not just as an advance on future payments. Otherwise, you’ll still pay the same total interest over time.
And finally, don’t burn yourself out. Paying off your mortgage early is a marathon, not a sprint. Plan your pace, commit to it, and adjust as life happens.
Financial Endurance: The True Goal
Debt payoff is mental fitness. The key isn’t speed — it’s endurance. It’s about showing up month after month, even when progress feels slow. There’s no perfect pace, only consistent effort. Focus hard in the beginning, stay steady through the middle, and push strong at the end.
It’s okay to slow down when life gets busy, but don’t quit the race entirely. The finish line might seem far away, but every extra payment gets you closer — faster than you think.
Time to Start Your Race
Your mortgage marathon won’t run itself. Whether you’re just lacing up or already halfway through, today is the perfect day to make your next extra payment — even if it’s just $50. Those small steps compound into massive results.
