There is no universal answer because the better choice depends on your mortgage rate, investment expectations, taxes, risk tolerance, liquidity needs, and overall financial priorities. Paying extra toward your mortgage provides a predictable benefit by reducing the balance on which future interest is charged. Investing the money could potentially produce a higher return, but investment returns are uncertain and can fluctuate. Liquidity is another important difference: money used to pay down a mortgage becomes home equity, while money kept in an investment or savings account may be easier to access. Some homeowners prefer a combination approach, such as making additional principal payments while continuing regular retirement or investment contributions. Before deciding, compare the potential mortgage interest savings with the potential after-tax investment return and consider your comfort with market risk. A mortgage payoff calculator can help you quantify the potential benefit of paying extra toward the loan.
