**more quickly**.

**reduce**the amount of

**total interest**paid.

## Reasons to Make Extra Payments

This approach is pretty easy to understand. You would anticipate that the loan would be repaid sooner if you made additional payments. The spreadsheet presumes that the additional monthly mortgage payments are made.

### Pay Less Total Interest

Each month, your payment consists of both interest and principal. The amount of interest paid is based on the remaining balance of the principal (i e. the current balance). That implies that you will end up paying less interest if you reduce the principal. The worksheet calculates this as the so-called “interest savings” (i e. the reduction in the interest expense).

### Extra Payments vs. Savings

It might seem strange to consider making extra payments as an “investment,” but it turns out that doing so is very similar to putting the money in a savings plan. The amount of reduced interest expense from making extra payments is equal to the amount of interest “gained” in the savings plan if the mortgage interest rate is the same as that of the savings plan (assumed both rates are fixed and compound monthly). The primary distinction is that cash is more easily accessible with a savings plan (or other comparable investment).

In the end, there are three key inquiries (which you must resolve for yourself):

Simply put, home appreciation or depreciation is a totally different issue. The mortgage interest rate determines the “interest savings” from extra payments, not the home’s present value.

I won’t respond to this question because I’m not a certified tax advisor, but keep in mind that interest earned in savings or investment accounts may be taxable, while interest paid on a mortgage is typically deductible. related blog articles.
