Calculating the amount of principal you’ve paid on a loan lets you determine the amount of equity you have in a purchase and what your new monthly payment would be if you refinanced the loan at a specific interest rate and for a given length of time. Calculating the interest paid on a loan lets you find the amount of interest you paid in a year, which you can often write off on your tax return.
