Prepaid Interest, Per Diem Calculation, and Closing Date Strategy
VA Loan Daily Interest Charges: What Veterans Pay at Closing and Why

CFPB — Closing Disclosure Guide
Daily interest charges — also called prepaid or per diem interest — are the interest you owe from your closing date through the end of that month. This is a standard closing cost on every VA loan. The amount depends on your loan amount, interest rate, and what day of the month you close. Closing later in the month reduces prepaid interest but means your first mortgage payment comes sooner.

What You Pay
- Per diem rate: Your daily interest rate equals your annual rate divided by 365, multiplied by your loan amount — on a $350,000 loan at 6.25%, that is $59.93 per day.
- Days charged: You pay from the closing date through the last day of the month — closing on the 15th means 16 days of prepaid interest on a 31-day month.
- Close early, pay more: Closing on the 1st of a 30-day month means 30 days of prepaid interest — approximately $1,798 on a $350,000 loan at 6.25% annual rate.
- Close late, pay less: Closing on the 28th means only 3 days of prepaid interest — approximately $180 on the same loan, a significant difference in cash due at closing.
Why It Exists
- Mortgage timing: Your first mortgage payment is not due until the first of the month after the next full month — prepaid interest covers the gap period.
- Example timeline: Close on March 15, your first payment is May 1 — prepaid interest covers March 15 through March 31, and the May payment covers all of April.
- Interest alignment: Mortgage payments are paid in arrears, meaning each payment covers the prior month's interest — prepaid interest aligns your first billing cycle.
- Not extra cost: Prepaid interest is not an additional charge — it is interest you would pay anyway as part of the normal amortization schedule, just collected upfront.
Closing Date Impact
- End of month: Closing in the last 3 days of the month minimizes prepaid interest to under $200 on most VA loans, reducing cash needed at closing.
- Beginning of month: Closing in the first week maximizes prepaid interest to $1,200 to $1,800 or more, but delays your first mortgage payment by nearly two months.
- Mid-month trade-off: Closing around the 15th produces moderate prepaid interest of $600 to $900 and a first payment due roughly 6 weeks after closing.
- Seller coordination: You cannot always choose your closing date — seller availability, contract timelines, and lender processing all influence when closing occurs.
On Your Closing Disclosure
- Section F: Prepaid interest appears in Section F (Prepaids) of your closing disclosure document, labeled as prepaid interest from closing date to month end.
- Per diem shown: The daily rate is listed next to the total prepaid amount so you can verify the calculation against your loan amount and interest rate.
- Compare to estimate: Your loan estimate should have projected this amount — compare the final closing disclosure figure to the estimate for accuracy.
- Cannot be financed: Prepaid interest must be paid in cash at closing or through seller concessions — it cannot be rolled into the VA loan amount like the funding fee.
Frequently Asked Questions
Can I avoid prepaid interest charges on a VA loan?
You cannot avoid them entirely, but you can minimize them by closing on the last day of the month. Closing on the 31st means only 1 day of prepaid interest. However, this is not always practical — closing dates depend on lender processing, seller timelines, and document preparation.
Is prepaid interest tax deductible?
Yes. Prepaid interest on a VA loan is deductible as mortgage interest in the year you pay it, just like the interest portion of your regular mortgage payments. Report it on Schedule A if you itemize deductions. Your lender will include it on Form 1098 at the end of the tax year.
Does prepaid interest increase my total loan cost?
No. Prepaid interest is not an additional charge on top of your normal interest. It is the same interest you would pay through regular monthly payments, collected upfront to align your first billing cycle. Whether you pay it at closing or through your first monthly payment, the total interest cost is the same.
The Bottom Line Up Front
Daily interest charges are the most misunderstood line item on a VA loan closing disclosure. They are not a fee, not a penalty, and not extra money the lender takes. They are simply the interest that accrues between your closing date and the end of the month, collected upfront because your first regular mortgage payment does not cover that period. The amount ranges from under $100 to over $1,800 depending on when you close, and the only lever you have is your closing date.
Every mortgage — VA, conventional, FHA — has prepaid interest. It is a function of how mortgage billing cycles work, not a VA-specific cost. Understanding the math eliminates the closing-day surprise and lets you make an informed decision about whether to push for an end-of-month close to save cash upfront.
How Per Diem Interest Is Calculated
The formula is straightforward. Your per diem (daily) interest rate equals your annual interest rate divided by 365, multiplied by your loan amount. That daily rate is then multiplied by the number of days remaining in the month after closing.
Loan amount: $350,000. Interest rate: 6.25%. Per diem rate: ($350,000 × 0.0625) / 365 = $59.93 per day. If you close on March 10, you owe 21 days of prepaid interest: $59.93 × 21 = $1,258.53. If you close on March 28, you owe 3 days: $59.93 × 3 = $179.79. Same loan, same rate — the closing date alone creates a $1,078.74 difference in cash due at closing.
The daily rate increases proportionally with your loan amount and interest rate. A $500,000 loan at 7.00% has a per diem of $95.89 — closing on the 1st of a 30-day month means $2,876.71 in prepaid interest. That is real money at a time when you are already writing checks for closing costs, funding fee, and moving expenses.
Why Mortgage Payments Work This Way
Mortgage payments are made in arrears. Your May 1 payment covers the interest that accrued during April. Your June 1 payment covers May. This continues for the life of the loan.
When you close on a home, there is a gap between the closing date and the start of the first full billing month. Prepaid interest covers that gap. If you close on March 15, your first payment is due May 1 (covering April interest). The prepaid interest at closing covers March 15 through March 31 — the partial month that no regular payment will cover.
This is why closing at the end of the month reduces prepaid interest: there are fewer days in the gap period. And it is why closing at the beginning of the month increases prepaid interest: the gap is nearly a full month.
Closing Date Strategy
Your closing date affects how much cash you need at closing and when your first mortgage payment is due. These two factors move in opposite directions.
| Close Date | Prepaid Interest Days | Approx. Prepaid Cost ($350K at 6.25%) | First Payment Due |
|---|---|---|---|
| March 1 | 31 days | $1,858 | May 1 |
| March 15 | 17 days | $1,019 | May 1 |
| March 28 | 4 days | $240 | May 1 |
| March 31 | 1 day | $60 | May 1 |
Closing later in the month saves cash at the closing table but gives you less time before your first payment is due. Closing on March 31 means only $60 in prepaid interest, but your first payment on May 1 is just 31 days away. Closing on March 1 means $1,858 in prepaid interest, but you have 61 days before that first payment — two full months to settle in and recover from moving costs.
Can Seller Concessions Cover Prepaid Interest?
Yes. Prepaid interest is a closing cost that can be covered by seller concessions on VA loans. Seller concessions on VA loans are capped at 4% of the purchase price. If your seller agrees to cover closing costs, prepaid interest is one of the items that can be included.
This is especially useful when closing early in the month would produce significant prepaid interest. If your closing date lands on the 5th and prepaid interest is $1,560, having the seller cover it along with other closing costs reduces your out-of-pocket cash at closing.
Prepaid Interest on VA Refinances
Prepaid interest applies to VA refinances just as it does to purchase loans. On an IRRRL or VA cash-out refinance, you pay per diem interest from the closing date of the new loan through the end of the month. The old loan's interest stops accruing on the payoff date, and the new loan's interest begins immediately.
There can be a brief overlap period where interest accrues on both loans if the payoff and funding dates do not align perfectly. Your closing agent and lender coordinate the payoff to minimize this overlap. On an IRRRL, where the funding fee is only 0.50% and closing costs are minimal, the prepaid interest may represent a larger percentage of your total out-of-pocket closing costs than on a purchase loan.
Prepaid Interest vs Discount Points
These are sometimes confused because both involve paying interest at closing, but they serve completely different purposes.
- Prepaid interest covers the gap between your closing date and month end — it is interest you owe regardless and is not optional.
- Discount points are an optional upfront payment to permanently reduce your interest rate — one point equals 1% of the loan amount and typically reduces the rate by 0.25%.
- Prepaid interest does not change your rate or payment amount — it is simply the timing of when you pay interest that would accrue anyway.
- Discount points are a financial decision based on how long you plan to keep the loan — the breakeven period determines whether points save money long-term.
How to Verify the Charge on Your Closing Disclosure
Before closing, review Section F (Prepaids) of your closing disclosure. The prepaid interest line should show the per diem rate, the number of days being charged, and the total amount. Verify the math: per diem rate × number of days should equal the total shown.
If the per diem rate does not match your calculation based on the loan amount and interest rate, ask your lender to explain the discrepancy. Common causes of differences include rounding, use of a 360-day year instead of 365 (some lenders use this convention), or an incorrect interest rate on the disclosure.
The Bottom Line
Prepaid interest is not a surprise cost if you understand how it works. It is the interest that accrues between closing day and month end, collected upfront because your first mortgage payment does not cover that period. Close later in the month to minimize it, or close earlier if you want more breathing room before your first payment. Either way, run the per diem calculation before closing so the number on your closing disclosure is expected, not a shock.
On a typical VA loan, the difference between closing on the 1st versus the 28th is $1,000 to $1,600 in cash due at closing. If cash is tight, push for a late-month close. If you need a longer runway before your first payment, close earlier and budget the extra prepaid interest.

Frequently Asked Questions
Why is prepaid interest different from my regular monthly interest?
It covers a different time period. Your monthly payment covers the prior full month's interest. Prepaid interest covers the partial month from closing day to month end — a period that no monthly payment will address. After the prepaid interest period ends, your regular monthly payment cycle begins.
Can I choose my closing date to minimize prepaid interest?
You can request a closing date near the end of the month, but the final date depends on your lender's processing timeline, the seller's availability, and how long underwriting and appraisal take. Communicate your preference early in the process so your lender and closing agent can try to accommodate it.
Does closing on the last day of the month eliminate prepaid interest entirely?
Nearly. Closing on the 31st of a 31-day month means 1 day of prepaid interest. On a $350,000 loan at 6.25%, that is approximately $60. You cannot eliminate it entirely because interest accrues on the day of closing, but one day is the minimum possible.
Do VA loans calculate per diem interest differently than conventional loans?
No. The per diem interest calculation is the same for VA, conventional, and FHA loans. Annual rate divided by 365 (or 360 for some lenders), multiplied by the loan amount, multiplied by the number of remaining days in the month. The VA does not impose any special daily interest rules.
Can prepaid interest be included in the VA loan amount?
No. Prepaid interest must be paid in cash at closing or through seller concessions. It cannot be financed into the VA loan amount. The VA funding fee can be financed, but prepaid interest is classified as a prepaid item, not a financeable cost.
What if my closing is delayed and the prepaid interest amount changes?
If your closing date shifts, the prepaid interest on your closing disclosure will be recalculated based on the new date. A delay from the 15th to the 20th reduces prepaid interest by 5 days. An acceleration from the 20th to the 10th increases it by 10 days. Your closing agent will update the disclosure with the correct figure before closing.
