When Is Your First Mortgage Payment Due? How Prepaid Interest and Closing Date Determine Your Timeline
Your first mortgage payment is due on the first of the month following a full month after closing. If you close on March 15, your first payment is due May 1. You pay prepaid interest at closing to cover March 15 through March 31, and then your regular payments begin the first of the second full month.

The Rule
- Standard timing: First payment due on the 1st of the month following one full month after your closing date
- Close early in month: Closing on March 5 means first payment is May 1 — you skip April entirely
- Close late in month: Closing on March 28 means first payment is May 1 — only 3 days of prepaid interest
- Action: Your Closing Disclosure will show the exact first payment date — verify it matches the standard calculation
Prepaid Interest
- What it covers: The interest from your closing date through the end of that month — you pay this at closing, not with your first payment
- Early close = more prepaid: Closing on the 5th means 25 to 26 days of prepaid interest at closing
- Late close = less prepaid: Closing on the 28th means only 2 to 3 days of prepaid interest at closing
- Action: Close near month-end to minimize prepaid interest at closing and keep more cash in your pocket
Payment Structure
- Mortgage payments are paid in arrears: Your May 1 payment covers the interest for the month of April, not May
- Escrow included: Your monthly payment includes principal, interest, property taxes, and homeowners insurance (PITI)
- Grace period: Most mortgages have a 15-day grace period — payment is not considered late until after the 15th of the month
- Action: Set up autopay with your loan servicer before your first payment is due to avoid any chance of a missed payment
Common Confusion
- Skipped month: It feels like you skip a month — you do not. Prepaid interest at closing covers the gap between closing and your first regular payment
- Servicer transfer: Your loan may be sold or transferred after closing — you will receive a notice with new payment instructions before your first due date
- Escrow shortage: Your first year escrow analysis may show a shortage if property taxes or insurance increase — this is normal and adjusts automatically
- Action: If your loan is transferred, make your payment to the new servicer — payments to the old servicer during the 60-day transfer window are protected by federal law

The Bottom Line Up Front
Your first mortgage payment is always due on the first day of the second full month after closing. The prepaid interest you pay at closing covers the gap. Close later in the month to reduce prepaid interest and maximize the time before your first payment.
This is one of the most common questions new homebuyers ask, and the answer surprises many people. You close on your house in March, but your first mortgage payment is not due until May 1. It feels like you are getting a free month. You are not. The interest for those final days of March is collected at closing as prepaid interest. The April interest is covered by your May 1 payment, because mortgage payments are made in arrears — each monthly payment covers the previous month’s interest. Understanding this timing helps you plan your cash flow for the transition from renting to owning.
- Mortgage payments are collected in arrears — your May 1 payment covers April interest, your June 1 payment covers May interest, and so on for the life of the loan
- Prepaid interest at closing covers the days between your closing date and the last day of the closing month — this bridges the gap before regular payments begin
- The amount of prepaid interest depends on your closing date and your loan’s daily interest rate — closing later in the month means less prepaid interest at closing
- Your first payment date is shown on your Closing Disclosure and your first billing statement from the loan servicer
How Is Your First Payment Date Calculated?
Take your closing date, skip to the end of that month, then skip one full month, and your first payment is due on the first of the next month. This formula works for every closing date.
| Close Date | Prepaid Interest Days | First Payment Due | Days Until First Payment |
|---|---|---|---|
| March 1 | 30 days | May 1 | 61 days |
| March 10 | 21 days | May 1 | 52 days |
| March 15 | 16 days | May 1 | 47 days |
| March 25 | 6 days | May 1 | 37 days |
| March 31 | 1 day | May 1 | 31 days |
Deal Math
On a $300,000 loan at 6.5%, your daily interest rate is approximately $53.42 per day. Closing on March 5 means 26 days of prepaid interest: $1,389. Closing on March 28 means 3 days: $160. The difference is $1,229 in cash-to-close. If you need to minimize your cash outlay, closing in the last few days of the month saves you real money at the closing table.
What Is Prepaid Interest and Why Do You Pay It at Closing?
Prepaid interest covers the cost of borrowing from your closing date through the end of that calendar month. It exists because mortgage payments are collected in arrears and your first regular payment does not cover this partial-month period.
Think of it this way: if you close on March 15, you start owing interest on March 15. Your first regular payment on May 1 covers April’s interest. March 15 through March 31 is a gap that no regular payment covers — so you pay that interest upfront at closing. It is not an extra fee. It is the cost of borrowing for those specific days, collected at the front end instead of the back end.
- Prepaid interest is calculated as: (loan amount × annual interest rate ÷ 365) × number of remaining days in the closing month
- This amount appears on your Closing Disclosure in the Prepaid section — it is a standard line item on every mortgage closing
- Prepaid interest is generally tax-deductible as mortgage interest in the year you close — check with your tax advisor for your specific situation
- The amount cannot be waived or negotiated — it is mathematically determined by your loan terms and closing date
Does Your Closing Date Matter for Your Budget?
Yes. Closing early in the month costs more upfront but gives you a longer gap before your first payment. Closing late in the month costs less upfront but shortens the gap. The total interest paid over the life of the loan is the same either way.
Choosing a closing date near the end of the month is a smart cash-flow strategy if you are tight on funds. You minimize prepaid interest at closing, which reduces your cash-to-close amount. The trade-off is a shorter buffer before your first regular payment. For most borrowers, the savings at closing are worth more than the slightly shorter gap, because the total interest cost is identical regardless of when you close.
- Close at end of month to minimize cash-to-close: 1 to 5 days of prepaid interest instead of 20 to 30 days saves $800 to $1,500 on a $300,000 loan at 6.5%
- Close at beginning of month to maximize gap before first payment: 50 to 60 days between closing and first payment gives you more time to rebuild cash reserves
- If you are moving from renting: time your closing to avoid paying both rent and a mortgage in the same month — closing near the end of the month aligns with most lease cycles
- The total interest paid over the life of the loan does not change based on closing date — early closing means more prepaid interest but fewer interest-accruing days before first payment, and the net cost is identical
The Bottom Line
Your first mortgage payment is due on the first of the month after one full month from closing. Prepaid interest at closing covers the gap. Close late in the month to minimize upfront costs, or early to maximize time before your first payment. Either way, the total interest cost is the same.
Set up autopay with your loan servicer as soon as you receive your welcome letter. If your loan is transferred to a new servicer before your first payment — which happens frequently — make sure to redirect your payment to the new servicer. Federal law protects you during the 60-day transfer window, but setting up autopay with the correct servicer from the start avoids confusion and prevents any risk of a missed first payment.
Frequently Asked Questions
What if I close on the first of the month?
Closing on March 1 means you pay 30 or 31 days of prepaid interest at closing (covering all of March), and your first regular payment is due May 1 (covering April). This is the most expensive closing day for prepaid interest but gives you the longest gap before your first payment.
Can my first payment date be different from the first of the month?
Standard mortgage payments are always due on the first of the month. Some lenders offer biweekly payment options, but the standard schedule starts on the first. The 15-day grace period means you can pay any time between the 1st and the 15th without a late fee.
What happens if my loan servicer changes before my first payment?
Under federal law (RESPA), both the old and new servicer must send you written notice of the transfer. During the 60-day transfer window, a payment sent to the old servicer cannot be treated as late. However, set up autopay with the new servicer as soon as you receive the transfer notice to avoid any confusion.
Is prepaid interest the same as discount points?
No. Prepaid interest covers the cost of borrowing for the remaining days in your closing month. Discount points are an optional upfront fee paid to reduce your interest rate for the life of the loan. They are separate line items on your Closing Disclosure and serve completely different purposes.
Do I need to make a payment the month I close?
No. You do not make a regular mortgage payment in the month you close. The prepaid interest collected at closing covers that period. Your first regular monthly payment is due on the first of the second full month after closing.
What if I miss my first mortgage payment?
A missed first payment is treated the same as any missed payment — after the 15-day grace period, a late fee is assessed (typically 4% to 5% of the payment amount). After 30 days past due, the servicer reports to the credit bureaus. Missing your first payment is especially damaging because it sets a negative tone for the entire loan relationship. Set up autopay immediately.
Does closing on a weekend or holiday affect my first payment date?
No. Your first payment date is calculated from the actual closing date regardless of weekends or holidays. If the first of the month falls on a weekend or holiday, most servicers accept payment on the next business day without a late fee. The 15-day grace period provides additional buffer.
Can I choose my own closing date to optimize my first payment timing?
You can request a closing date, but the actual date depends on coordination between the lender, title company, seller, and your schedule. If minimizing cash-to-close is your priority, request a closing date in the last 3 to 5 business days of the month. Your loan officer and real estate agent can work to accommodate your preferred timing.
