Comparing loan interest savings vs. investment returns
Struggling to decide – invest or pay off mortgage? When you have extra cash – whether from a bonus, inheritance, or years of disciplined savings – one big financial question arises:
Should you pay off your mortgage early or invest that money instead?
The best choice depends on your financial situation, interest rates, investment opportunities, and how close you are to retirement. Paying off your mortgage offers peace of mind and guaranteed interest savings, while investing could generate higher returns over time. Let’s break down the key factors to help you make an informed decision.
How paying off your mortgage early impacts your finances
Every mortgage payment consists of two parts: principal (the loan amount) and interest (the cost of borrowing). In the early years of a 30-year fixed mortgage, most of your payment goes toward interest. Over time, more of it is applied to the principal.
For example, let’s say you have a $200,000 mortgage at a 4.5% fixed interest rate. If you keep making regular monthly payments, your mortgage balance will decline gradually over time.
Now, let’s assume you have $100,000 in savings and are considering paying down your mortgage 10 years early. Here’s how much you would save in interest at different mortgage rates:
Interest savings by paying off mortgage 10 years early
- At 3.5% interest rate → You save $101,814 in interest
- At 4.5% interest rate → You save $133,619 in interest
- At 5.5% interest rate → You save $166,444 in interest
Key takeaway: The higher your mortgage rate, the more interest you save by paying off the loan early.
How investing instead of paying off your mortgage can benefit you
If you invest your money instead of paying off your mortgage, you could potentially earn higher returns than the interest saved on your loan.
Let’s assume you take $100,000 and invest it in the market for 10 years, with different potential rates of return:
Investment growth over 10 years
- At 3.5% return → Your investment grows to $134,391
- At 4.5% return → Your investment grows to $179,084
- At 5.5% return → Your investment grows to $236,736
Key takeaway: If your investment earns a higher return than your mortgage rate, investing could be the better financial decision.
However, investing comes with risks. The stock market fluctuates, and there’s no guarantee of returns – unlike the certainty of saving interest with an early mortgage payoff.
Comparing both options: what’s right for you?
When paying off your mortgage early makes sense
- Your mortgage rate is high (above 5%), making interest savings significant.
- You’re near retirement and want to reduce fixed expenses.
- You have no high-interest debt, such as credit cards or personal loans.
- You prioritize financial security and prefer being debt-free.
When investing might be the better choice
- Your mortgage rate is low (under 4%), making investing more attractive.
- You have an emergency fund covering 3-6 months of expenses.
- You maximize tax benefits, like mortgage interest deductions.
- You’re comfortable with long-term market growth and volatility.
The best of both: A balanced approach
Many financial experts recommend a hybrid strategy – reducing debt while still investing for the future.
A balanced approach might include:
- Making extra mortgage payments while keeping some funds invested.
- Investing in tax-advantaged accounts such as IRAs, 401ks before prioritizing early mortgage payoff.
For example, if your mortgage rate is 4.5%, but your investments have a potential return of 7%, investing may be the smarter move. However, if eliminating debt brings you peace of mind, a mortgage payoff could be the right path.
Key factors to consider before making a decision
- Compare your mortgage rate to investment returns: If your investments are likely to outperform your mortgage interest rate, investing may be the better choice. However, market returns are not guaranteed, while mortgage interest savings are.
- Pay off high-interest debt first: If you have credit card balances, personal loans, or other high-interest debts, focus on paying those down first before considering mortgage payoff or investing.
- Take advantage of tax benefits: Mortgage interest is tax-deductible on loans up to $750,000, reducing your overall tax liability. Compare this tax advantage with potential investment gains.
- Keep liquidity in mind: Once you pay off your mortgage, your money is tied up in your home. Unlike investments, it’s not easily accessible unless you refinance or sell your property.
Final thoughts: making the right financial move
Choosing between paying off your mortgage or investing isn’t just about numbers – it’s about what works best for your financial goals, risk tolerance, and long-term plans.
Key takeaways:
- Paying off your mortgage provides financial security and guaranteed savings.
- Investing offers higher potential returns but comes with risk.
- A hybrid approach allows you to balance debt reduction with wealth-building.
Both options have merits, and the best approach depends on your individual situation. If you’re unsure, consider speaking with a fiduciary financial advisor who can provide personalized guidance based on your unique financial picture.
