Payoff vs Invest Calculator

Should you pay off your mortgage early or invest the difference? Compare both paths honestly — interest saved vs compounded gains.

Recommendation

Invest the extra

Your investments earn roughly 0.1% after tax vs 6.5% on your loan — a 0.3-point spread in favor of investing. Over the full term, that compounds into ~$18,910 more net worth by letting the extra cash grow in the market instead of killing loan principal early.
