Pay Off Mortgage vs Invest Calculator

Pay Down the Loan or Invest the Cash? See Which Comes Out Ahead.

Use our Pay Off Mortgage vs Invest Calculator to see whether spare money does more for you paying down your mortgage or invested.

Enter a one-time lump sum, a monthly amount, or both, with your mortgage rate, the return you expect and the number of years. The calculator shows what each choice is worth at the end and which one comes out ahead.

Every dollar paid toward the mortgage saves interest at the mortgage rate — a guaranteed return. Investing comes out ahead only if your return beats the break-even return: your mortgage rate compounded monthly.

Keep the years no longer than the time left on your mortgage. Returns are before taxes and fees and are not guaranteed. To see how extra payments shorten your loan, use our Mortgage Accelerator Calculator.
