🧮 Pay Off vs Invest Calculator — 2026
📊 The Math: Why Investing Usually Wins
The core principle is simple: if your after-tax investment return is higher than your mortgage rate, investing wins. Here's the 2026 breakdown:
| Factor | Pay Off Mortgage | Invest |
|---|---|---|
| Return rate | 6.5% (mortgage rate = guaranteed return) | 9% avg (S&P 500, not guaranteed) |
| After-tax return | 6.5% (mortgage interest deduction limited) | 6.84% (24% tax bracket) |
| $100K over 25 years | $95K interest saved | $275K investment growth |
| Risk | None (guaranteed) | Market volatility |
| Liquidity | Low (cash tied in home equity) | High (can sell investments) |
| Net difference | $95K | $275K - $95K extra interest = $180K ahead |
⚠️ 4 Factors That Change the Answer
Your Mortgage Rate
If your rate is above 7%, paying off the mortgage becomes more attractive. At 6%, investing wins clearly. At 8%+, paying off is the better financial choice. Current 30-year fixed: 6.37% (July 2026).
Your Risk Tolerance
Investing returns are NOT guaranteed. The S&P 500 can drop 20-30% in a bad year. If you can't stomach volatility, paying off the mortgage gives you a guaranteed 6.5% return with zero risk.
Your Time Horizon
Over 20+ years, investing almost always wins due to compound growth. Over 5 years, the difference is small and market timing risk is higher. If you're near retirement, paying off the mortgage provides peace of mind.
Tax Situation
Mortgage interest is deductible only if you itemize (standard deduction is $14,600 single / $29,200 married in 2026). If you take the standard deduction, paying off the mortgage is more attractive because you're not benefiting from the deduction.

🔄 Third Option: Refinance Instead
Before deciding to pay off or invest, check if refinancing is a better move. If your current rate is above 7% and today's rates are 6.37%, refinancing could save you $200+/month AND let you invest the difference.
Example: $300K loan at 7.5% → refinance to 6.37% = $227/month savings = $2,724/year. Invest that $2,724/year at 9% for 25 years = $188,000. Check refinance rates →
