Home & Housing Calculators
Mortgage Payoff vs. Invest Calculator
Compare making extra mortgage payments with investing the difference, including interest saved, investment growth, payoff timing, liquidity tradeoffs, and long-term net position.
Paying extra toward a mortgage can reduce interest and shorten your loan, while investing the same money may create more long-term growth but adds market risk. This calculator compares both paths using your mortgage, investment return, time horizon, and extra payment assumptions.
Educational estimate only. This calculator is not financial, investment, tax, legal, mortgage, or professional advice.
Compare the same extra cash flow as either mortgage prepayment or investing. The investment path uses a steady return estimate, not a market forecast.

Home appreciation is shown for context. The main comparison focuses on mortgage balance and invested assets.
Extra money available
Use the same extra cash flow in both paths so the comparison stays balanced.
Investment assumptions
Returns are not guaranteed. This uses a steady expected return for comparison.
Optional estimate for taxes, fund fees, or other drag on returns.
Optional tax and mortgage assumptions
These are rough assumptions only and do not estimate actual itemized deductions or tax eligibility.
Use 0 if you do not want to estimate any mortgage interest tax benefit.
Scenario presets
Use a preset to move quickly, then edit the numbers. Presets replace assumptions rather than compounding them.
Frequently asked questions
Is it better to pay off a mortgage or invest?+
It depends on mortgage rate, expected return, time horizon, taxes, risk tolerance, and liquidity needs. This calculator estimates the tradeoff without recommending one answer for everyone.
How does the mortgage interest rate affect the decision?+
A higher mortgage rate can make extra payoff more attractive because each extra dollar may avoid more interest.
How does investment return affect the decision?+
A higher expected investment return can make investing look stronger, but returns are not guaranteed and can vary over time.
What does the break-even investment return mean?+
It is the approximate annual return where the payoff path and investing path produce a similar net position under the entered assumptions.
Does this calculator include taxes?+
It includes only optional simplified tax-drag and mortgage-interest assumptions. It does not calculate itemized deductions or actual tax outcomes.
Why does liquidity matter?+
Mortgage payoff builds home equity, while investing may keep more assets accessible. That flexibility can matter even when total net positions look similar.
What happens if my mortgage is paid off early?+
If selected, the calculator assumes the freed-up mortgage payment is redirected into investments after payoff.
Is this financial or investment advice?+
No. This calculator is for educational estimates only and is not financial, investment, tax, legal, mortgage, or professional advice.
