Calendar-Day Proration Step by Step

For an actual calendar-day proration, divide the annual amount by 365, or 366 for a leap year when the question requires the actual year, then multiply by the days allocated to the party. Count closing day for exactly one party and state whether the period is inclusive.

The Rule

PSI publishes a weight for the complete official area, not a guaranteed count for this individual calculation. Follow the stated facts, units, time basis, and rounding instruction.

Formula and variables

Actual calendar-day proration: Proration = annual amount / actual days in year x calendar days allocated
Variables used in Actual calendar-day proration
Symbol or termMeaning
Actual year days365 in an ordinary year or 366 in a leap year when actual-year instructions apply
Allocated calendar daysInclusive day count assigned to the party under the stated closing-day convention
Daily rateAnnual amount divided by actual year days

Step-by-step method

  1. Confirm that the question requires actual calendar days.
  2. Determine whether the year is ordinary or leap when that affects the stated method.
  3. Write who owns closing day and mark it once.
  4. Add actual days by month for the responsible period.
  5. Multiply the daily rate by the day count, then separately assign the debit and credit.

Georgia-specific distinction

A Georgia contract or closing statement can specify proration conventions. The exam must provide enough facts to allocate the day and payment timing. Do not assume every Georgia closing gives closing day to the buyer or seller.

Worked examples

Example 1: Seller owns through closing day

Scenario. In a non-leap year, annual taxes are $4,380. Closing is April 10 and the seller owns closing day. Use actual days.

  1. Seller days = January 31 + February 28 + March 31 + April 10 = 100.
  2. Daily rate = $4,380 / 365 = $12.
  3. Seller share = 100 x $12 = $1,200.

Answer. The seller's allocated amount is $1,200 before deciding the debit-credit direction from payment timing.

Reasonableness check. One hundred days at exactly $12 per day gives a clean $1,200 result.

Example 2: Buyer owns closing day

Scenario. A non-leap-year closing occurs July 1 and the buyer owns closing day. How many days are allocated to the seller from January 1?

  1. Count January through June only: 31 + 28 + 31 + 30 + 31 + 30.
  2. Seller days = 181.
  3. July 1 belongs to the buyer and is not counted for the seller.

Answer. The seller is allocated 181 days.

Reasonableness check. July 1 is the 182nd day of a non-leap year, so the prior 181 days belong to the seller.

Common exam traps

  • Using 30-day months in an actual-day problem
  • Forgetting February has 29 days in a leap year
  • Counting closing day for both buyer and seller
  • Assuming the payment status from the calendar alone

Original practice questions with detailed explanations

These original instructional questions map to the July 1, 2026 PSI outline. They are not copied from PSI or any live examination. Write the setup before opening the explanation.

Question 1

In a non-leap year, how many actual days run from January 1 through March 31 inclusive?

  1. A. 89
  2. B. 90
  3. C. 91
  4. D. 92
Show answer and explanation →

Answer: B. 90

January 31 + February 28 + March 31 = 90 days.

Question 2

Annual expense is $7,300 in a non-leap year. What is the actual daily rate?

  1. A. $19.72
  2. B. $20.00
  3. C. $20.28
  4. D. $24.00
Show answer and explanation →

Answer: B. $20.00

$7,300 / 365 = $20 per day.

Question 3

Closing is May 1 and the buyer owns closing day. Which party receives May 1 in the day count?

  1. A. Seller only
  2. B. Buyer only
  3. C. Both
  4. D. Neither
Show answer and explanation →

Answer: B. Buyer only

The stated convention assigns closing day to the buyer, so it appears exactly once in the buyer period.

Calendar-Day Proration Step by Step questions

Facts checked against the current PSI Candidate Information Bulletin and GREC sources. Last reviewed August 2, 2026. Editorial standards.

Is Calendar-Day Proration Step by Step on the Georgia real estate exam?

It maps to XI.A.3 Calculations for Transactions: Real property tax and other prorations in the official Real Estate Calculations area. PSI assigns 7% of the 100-question national portion to the complete area but does not guarantee a count for this individual formula.

What formula should I use for Calendar-Day Proration Step by Step?

Proration = annual amount / actual days in year x calendar days allocated

What Georgia-specific point should I remember?

A Georgia contract or closing statement can specify proration conventions. The exam must provide enough facts to allocate the day and payment timing. Do not assume every Georgia closing gives closing day to the buyer or seller.

Can I use a calculator on the Georgia real estate exam?

PSI provides an online calculator during the examination. Handheld calculators are prohibited. Write the setup and label the units before entering numbers.
