Prepaid mortgage interest usually covers the days from closing through the end of that month before the regular payment cycle begins. Divide the annual interest by 365 for an estimated daily amount, then multiply by the disclosed number of days. It is a timing charge, not automatically duplicate interest. Verify the exact dates and amount in Section F of the Closing Disclosure.
Current cash-to-close discussions repeatedly ask why a later closing date changes the final amount. Prepaid interest is one of the few lines that can move almost day by day.
Start here: a practical action plan
- Open the cited primary guidance and the latest Loan Estimate, Closing Disclosure, policy, or escrow statement.
- Replace the hypothetical loan amount, dates, rates, credits, and bills with the transaction’s actual figures.
- Ask the lender or servicer for a written line-by-line explanation of any difference, condition, or deadline.
- Preserve the disclosure, quote, confirmation, transfer receipt, and final settlement or account result.
- Treating a verbal estimate, forum answer, or advertised rate as the final transaction term.
- Comparing one payment or fee while ignoring cash at closing, time in the loan, taxes, insurance, and reserves.
- Moving money or changing the transaction before the lender confirms the documentation and underwriting effect.
Locate the dates before calculating the charge
Find Prepaid Interest in Section F of the Loan Estimate or Closing Disclosure. It should show the daily dollar amount, start date, end date, and number of days. CFPB guidance explains that the charge covers interest accruing between closing and the period covered by the first scheduled payment.
Confirm whether the lender uses a 365-day calculation and whether the closing day is included. Use the disclosure rather than applying a generic convention because loan documents and settlement timing control the final amount.
Compare closing dates without isolating one line
A later closing can reduce prepaid interest because fewer days remain in the month, but that single saving does not prove a later date is cheaper. Rent overlap, seller prorations, movers, rate-lock extensions, and possession terms can offset it.
Ask the settlement agent for side-by-side cash-to-close estimates if the date is flexible. Keep every assumption the same except the date, and confirm whether moving the date affects the rate lock or disclosure timing.
Worked example: 17 days of prepaid interest
Example: a $320,000 loan at 6.75 percent produces estimated annual interest of $21,600. Dividing by 365 gives $59.18 per day, rounded to cents. A closing with 17 charged days produces about $1,006.06 of prepaid interest.
A closing with 3 charged days produces about $177.54. The line-item difference is $828.52, calculated as $1,006.06 - $177.54. This example does not include tax prorations, insurance, lock costs, rent, or the value of earlier occupancy.
| Illustrative timing | Daily amount | Days | Prepaid interest |
|---|---|---|---|
| Earlier close | $59.18 | 17 | $1,006.06 |
| Later close | $59.18 | 3 | $177.54 |
| Line-item difference | $828.52 |
Reconcile the first payment and final disclosure
Compare the first payment date with the prepaid period. The first regular mortgage payment normally covers a later interest period, so the closing charge and first payment should not be described as the same days without checking the note and payment schedule.
Review the final disclosure before funding because a changed closing date can change the prepaid-interest line. Save the signed disclosure and first statement so an unexpected date or amount can be documented clearly.
- Read the Section F dates and daily amount.
- Compare all costs affected by the closing date.
- Confirm the first payment period.
- Recheck the final disclosure after any date change.
