It's like giving your mortgage a turbo boost towards payoff!

🤔 Did You Know?
If you start making extra payments early in your mortgage term, the impact is even greater. This is because in the early years of a mortgage, a larger portion of your payment goes towards interest rather than principal.
Factors to Consider When Calculating Extra Payment Impact 🧮
- Interest Rate: Higher interest rates mean greater potential savings from extra payments.
- Loan Term: Longer loan terms provide more opportunity for savings.
- Loan Amount: Larger loan amounts result in more significant savings from extra payments.
- Timing: Starting extra payments early in your loan term maximizes savings.
- Consistency: Regular extra payments typically lead to greater savings than sporadic lump sums.

- Biweekly Payments: Pay half your mortgage every two weeks, resulting in 13 full payments per year.
- Annual Lump Sum: Use tax refunds or bonuses to make one large extra payment each year.
- Increase Payments Gradually: Boost your payment amount each year as your income grows.
- Windfall Allocation: Dedicate a portion of any unexpected money (gifts, inheritance, etc.) to your mortgage.
Important Considerations When Making Extra Payments ⚠️
- Prepayment Penalties: Some loans may have penalties for paying off the mortgage early. Always check your loan terms!
- Opportunity Cost: Consider whether the money used for extra payments could potentially earn higher returns if invested elsewhere.
- Emergency Fund: Ensure you have a solid emergency fund before committing to extra mortgage payments.
