• This amount can be reduced if you delay your loan closing date until the end of the month

## Why is Prepaid Interest Charged on a Mortgage?

This is based on the interest rate of your loan term. Lenders are legally required to disclose the amount of prepaid interest for your mortgage before your closing date.

This amount will be listed on your loan estimate and closing disclosure form. It will summarize the details of your monthly mortgage payments along with your loan costs. The amount will be listed under a section titled “prepaids” and will be grouped under your total loan.

• After you have your daily rate, multiply it by your loan amount to calculate your daily loan interest amount = 0.0082% x 300,000 = \$24.65
• Next, you will need to multiply the number of days between your closing and first payment by your daily interest charge = \$24.65 x 15 days = \$369.86
