Prepaid Rent Calculator
Paying rent in advance? Enter the monthly rent and either the number of months or a start and end date: the tool shows the total prepaid amount, the days covered, the daily rent rate, and the monthly amortization for your books.
Date math uses calendar days. Daily rate = monthly rent ÷ 30.44 (average month length, 365.25 ÷ 12). The end date is not counted as a covered day.
Quick Answer
$1,500/month for 6 months: total prepaid $9,000.00, covering 183 days, daily rate $49.28, monthly amortization $1,500.00. By dates, 2026-10-01 to 2027-03-31: 181 days, total $8,919.19. Enter your own rent and period in the calculator for the exact figures.
Key takeaways
- The daily rate here is monthly rent ÷ 30.44, the average month length (365.25 ÷ 12). One fixed divisor keeps every period comparable.
- Date-range mode counts exact calendar days from the start date up to, but not including, the end date. For a lease running through March 31, enter April 1 as the end date.
- Prepaid rent is an asset on the payer's books, not an expense: debit Prepaid Rent, credit Cash, then move one month's amortization to Rent Expense each month.
- Landlords see the mirror image: cash received in advance is a liability (unearned rent) until earned, though the IRS taxes advance rent in the year it is received.

How to use the prepaid rent calculator
Pick a mode, enter the rent, click Calculate. The results stay hidden until you calculate.
- Monthly rent: the contract rent for one full month. $1,500 is pre-filled as the worked example.
- Calculate by: choose "Number of months" for a plain prepayment (1 to 600 whole months) or "Date range" when the period does not align with calendar months.
- Months to prepay: whole months only. If you type 6.5, the tool truncates to 6 months, so round your period to whole months first or switch to date mode.
- Start and end dates: appear in date-range mode. The end date is exclusive: October 1 to October 2 counts as 1 day.
- Read the four lines: total prepaid, the coverage period with the day count, the daily rate, and the monthly amortization figure for your books.
The formula
Three lines of arithmetic. Daily rate = monthly rent ÷ 30.44. Total prepaid = daily rate × days covered. Monthly amortization = total ÷ (days ÷ 30.44), the straight-line monthly expense for your books.
The 30.44 is the average month length: 365.25 ÷ 12 = 30.4375, rounded to 30.44. (An older version of this page described it as 365 ÷ 12, which is 30.4167 and slightly off; the tool itself always used 30.44, and so does this page now.) A single fixed divisor is a deliberate choice: it makes a 6-month prepayment and a 181-day date range directly comparable, where dividing by the actual days of each calendar month would give a different daily rate every month. In months mode the day count is months × 30.44 rounded to the nearest day; in date mode it is the exact calendar-day difference. Because amortization divides the total back by days ÷ 30.44, it always lands back on the monthly rent, which is exactly what straight-line amortization should do.
Worked example, checked against this exact tool
The $1,500, 6-month case is pre-filled. Running it gives total prepaid $9,000.00, coverage "6 months (183 days)", daily rate $49.28, and monthly amortization $1,500.00. The formula line confirms: daily rate = 1500 ÷ 30.44 = $49.28, total = $49.28 × 183 = $9,000.00. Every row below is a real run of the calculator.
| Inputs | Total prepaid | Days | Daily rate | Monthly amortization |
|---|---|---|---|---|
| $1,500 × 6 months | $9,000.00 | 183 | $49.28 | $1,500.00 |
| $2,200 × 12 months | $26,400.00 | 365 | $72.27 | $2,200.00 |
| $1,500 × 1 month | $1,500.00 | 30 | $49.28 | $1,500.00 |
Date-range mode, same rent of $1,500/month:
| Start to end | Days | Total prepaid | Monthly amortization |
|---|---|---|---|
| 2026-10-01 to 2027-03-31 | 181 | $8,919.19 | $1,500.00 |
| 2028-02-01 to 2028-03-01 (leap year) | 29 | $1,429.04 | $1,500.00 |
| 2026-10-01 to 2026-10-02 | 1 | $49.28 | $1,500.00 |
The leap-year row shows why date mode exists: February 2028 has 29 days, and the tool counts all 29 at the daily rate. Note the 181-day row costs $8,919.19 while 6 whole months costs $9,000.00: the date range covers 181 days, the months mode covers a rounded 183, and the $80.81 gap is the two-day difference, not an error.
The accounting treatment
Prepaid rent is an asset, not an expense. On payment, debit Prepaid Rent and credit Cash; each month, move one month's amortization to Rent Expense by debiting Rent Expense and crediting Prepaid Rent. That is the matching principle at work: the cost is recognized in the period the occupancy is used, not the period the cash left. AccountingTools' prepaid rent guide lays out the same treatment, including the cash-basis exception where the payment is expensed when paid.
On payment: Dr Prepaid Rent $9,000 Cr Cash $9,000
Each month-end: Dr Rent Expense $1,500 Cr Prepaid Rent $1,500
Classification follows the 12-month rule: prepaid rent consumed within the next 12 months sits in current assets; any portion relating to periods beyond one year is presented as a non-current asset, as AccountingTools' balance sheet guide describes. Under the lease standards the picture is richer: both IFRS 16 and ASC 842 fold prepaid rent into the right-of-use asset rather than leaving it as a standalone prepaid account for capitalized leases, which the FinQuery ASC 842 guide explains with examples. For short leases of 12 months or less, lessees can elect the simpler straight-line treatment, which is exactly what this calculator's amortization line computes. The related accrued rent calculator covers the opposite timing case, rent owed but not yet paid.
Mid-month starts and proration
Use date-range mode when occupancy does not align with calendar months: it counts exact calendar days at the daily rate, which is how most landlords prorate partial months. Four methods circulate in practice, and they give different answers.
| Method | Daily rate for $1,500 rent | Character |
|---|---|---|
| This calculator: ÷ 30.44 | $49.28, every month | One fixed rate; every period comparable |
| Actual days in the month | $48.39–$53.57, varies | Most precise per month; tenants can verify it |
| Flat 30 days | $50.00, every month | Simplest; slightly overcharges in 31-day months |
| Annual ÷ 365 | $49.32 | Technically the truest daily value; hardest to explain |
The honest caveat: if your lease specifies a proration method, the lease wins. The TransUnion SmartMove guide recommends putting the method in the lease precisely to avoid disputes, and the National Apartment Association's reference guide works its proration examples on the actual-days-in-month method. Whatever method you use, check local law: California's Civil Code §1946, for example, makes rent due only through the termination date on month-to-month tenancies, which is a statutory right to proration. For a different unit of rent time, the monthly-to-weekly rent calculator converts between billing periods, and the daily rent calculator isolates the per-day figure.
Whose books are you on: tenant vs landlord
The same cash is two different things depending on whose books you read. To the payer it is a current asset (prepaid rent); to the landlord who received it, it is a liability called unearned rent until the period it covers arrives. A lease is the contract that creates both sides of that entry. Taxes run on their own track: the IRS Publication 527 requires landlords to include advance rent in rental income in the year received, regardless of the period covered or the accounting method. So a landlord who collects $9,000 in December for January through June reports the $9,000 that December for tax, while carrying it as a liability on the books until each month is earned.
What competing calculators miss
Proration tools answer half the question. The typical prorated-rent calculator handles one partial month: move-in on the 15th, pay half. Lease-accounting tools bury prepayments inside present-value math built for ASC 842 compliance. Neither answers the plain question at the heart of this calculator: how much upfront, what it covers, in both whole months and exact dates, with the amortization figure accountants need.
- Two modes, one page. Whole-month prepayments and exact date ranges use the same 30.44 daily rate, so the answers are comparable instead of computed two different ways.
- The amortization line. Most calculators stop at the total. The monthly amortization figure is what actually goes into the books each month, and it is the line bookkeepers ask for.
- Both sides of the entry. Tenant-side asset treatment and landlord-side liability and tax treatment are explained together, with the journal entries, instead of leaving you to translate a tenant tool into landlord books.
- Honest boundaries. The 600-month cap, the whole-month truncation, and the exclusive end date are stated on the page, not discovered by surprise.
One context where the amortization figure matters beyond bookkeeping is affordability: landlords qualifying tenants against income often use rules of thumb like the 40x rent rule, which annualizes the same monthly rent this calculator starts from.
Frequently asked questions
Monthly rent times the number of months, or the daily rate times the exact number of days. For example, $1,500 times 6 months is $9,000, and $49.28 per day times 181 days is $8,919.19.
Monthly rent divided by 30.44, the average month length. For $1,500 rent that is $1,500 divided by 30.44, or $49.28 per day. The 30.44 comes from 365.25 divided by 12, so leap years are already averaged in.
Yes, on the payer's books it is usually a current asset: you have paid for future occupancy. If any part of the prepayment covers periods more than 12 months out, that part is classified as a non-current asset instead.
On payment: debit Prepaid Rent and credit Cash. At each month end: debit Rent Expense and credit Prepaid Rent for one month's amortization. For a $9,000 six-month prepayment, the monthly entry moves $1,500 from the asset to expense.
Straight-line: total prepaid divided by the months covered, recognized as Rent Expense each month. The calculator's monthly amortization line is that figure: total divided by (days divided by 30.44), which always lands back on the monthly rent.
Use the date-range mode. It counts exact calendar days between your start and end dates at the daily rate, which is how landlords prorate partial months. The end date is exclusive, so a lease running through March 31 needs April 1 as the end date.
No. The tool counts calendar days from the start date up to, but not including, the end date: October 1 to October 2 is 1 day. Enter the day after your last occupied day as the end date.
For tax purposes, yes. The IRS requires landlords to include advance rent in rental income in the year it is received, regardless of the period it covers or the accounting method used. On the financial statements it stays a liability, called unearned rent, until each month is earned.
