Understanding the "Locked-In" Rate Dilemma
If you bought or refinanced a home in 2020 or 2021, you likely secured a mortgage rate between 2.5% and 3.5%. Today, average rates are hovering around 6.5% to 7.0%. This creates the "lock-in effect": homeowners are reluctant to sell because moving to a new home means giving up a historically cheap mortgage for a much more expensive loan.
This calculator is designed to quantify exactly what giving up that rate will cost you. It helps you answer the crucial question: "Is a better home worth the premium of a higher rate?"
How the Locked-In Rate Calculator Works
- Monthly Payment Gap: The difference in principal and interest (P&I) payments between your current loan and the new loan.
- Extra Cost Over Planned Stay: If you plan to move anyway in 5 years, how much extra will you pay in interest/payments by moving now instead of staying in your low-rate home?
- Break-Even Rate: The target interest rate the new loan would need to achieve so that your new monthly P&I payment exactly matches your current P&I payment. If rates drop to this level, you can refinance and eliminate the rate premium entirely!
3 Factors Beyond the Math: When You Should Move Anyway
Financial calculations are critical, but they aren't the only thing that matters. You might want to move despite the rate premium if:
- Major Life Changes: Expanding families, new job opportunities, marriage, or divorce often require moving regardless of rate cycles.
- Downsizing to Cash: If you are selling a large home and buying a smaller one with cash or a very small loan, the higher interest rate will have a minimal impact on your total monthly expenses.
- Significant Quality of Life Improvements: Shorter commutes, better school districts, or moving closer to family can offer value that can't be measured purely in dollars.
