Mastering Proration Calculations Step by Step for the Alberta Broker Exam

Last updated: April 2026

For real estate professionals upgrading their license, mastering the financial and mathematical components of the industry is non-negotiable. Whether you are reviewing closing costs, preparing a Statement of Adjustments, or studying for your upcoming regulatory exams, understanding how to accurately calculate prorations is an essential skill. This guide will walk you through proration calculations step by step, ensuring you are fully prepared for the math portion of the Complete Alberta Real Estate Broker Exam Exam Guide.

Understanding Prorations in Alberta Real Estate

In real estate, proration (or adjustment) is the equitable division of ongoing property expenses or income between the buyer and the seller. Because real estate transactions rarely close on the exact first or last day of a billing cycle, costs like property taxes, condominium contributions (HOA fees), and rental income must be divided so that each party only pays for the exact number of days they own the property.

For the Alberta Broker Exam, administered by the Real Estate Council of Alberta (RECA), you must demonstrate a flawless understanding of how these adjustments are calculated and applied to the final Statement of Adjustments. While concepts like earnest money and escrow deal with deposits held in trust, prorations deal with the final debits and credits required to close the transaction fairly.

The Standard Alberta Proration Rule (AREA Contract)

To calculate prorations correctly in Alberta, you must follow the standard rules established in the Alberta Real Estate Association (AREA) Residential Purchase Contract. The most critical rule to remember for your exam is who owns the Completion Day.

According to standard AREA contracts, the Buyer is responsible for all property expenses and is entitled to all property income on the Completion Day (also known as Possession Day).

Seller's Responsibility: Up to 11:59 PM on the day before the Completion Day.
Buyer's Responsibility: From 12:00 AM on the Completion Day onward.

Step-by-Step Proration Formula

When you encounter a proration question on the exam, follow this systematic five-step process to ensure accuracy:

Step 1: Identify the Total Amount and the Period

Determine the total cost of the item being prorated and the time period it covers. For example, property taxes are typically annual, while condominium contributions and rent are monthly.

Step 2: Calculate the Daily Rate (Per Diem)

Divide the total amount by the exact number of days in the period to find the daily rate. Note for Alberta Exams: Always use a 365-day year for annual calculations, unless the question specifically states it is a leap year (366 days). For monthly calculations, use the exact number of days in that specific month (e.g., 31 days for October, 30 days for November).

Step 3: Determine the Number of Days for Each Party

Count the exact number of days the seller owned the property and the exact number of days the buyer will own the property during the billing period, remembering that the buyer takes over on the Completion Day.

Step 4: Multiply the Days by the Per Diem

Multiply the buyer's days and the seller's days by the daily rate to determine each party's financial share of the expense.

Step 5: Determine the Debit and Credit

Determine who has already paid the bill (or who will pay it in the future) to assign the correct debits (charges) and credits (refunds) on the Statement of Adjustments.

Alberta Proration Practice Examples

Scenario 1: Annual Property Taxes

The Scenario: A property in Calgary is sold with a Completion Day of August 15. The annual property taxes are $3,650. The seller has already paid the property taxes in full for the entire year. Calculate the adjustment.

The Calculation:

Period & Amount: Annual (365 days) / $3,650.
Per Diem: $3,650 ÷ 365 days = $10.00 per day.
Count the Days:
- Seller owns from Jan 1 to Aug 14. (Jan: 31, Feb: 28, Mar: 31, Apr: 30, May: 31, Jun: 30, Jul: 31, Aug: 14) = 226 days.
- Buyer owns from Aug 15 to Dec 31. (365 total days - 226 seller days) = 139 days.
Financial Share: Buyer's share = 139 days × $10.00 = $1,390.
Debit/Credit: Because the seller already paid the buyer's share, the seller must be reimbursed.
Result: Credit Seller $1,390 / Debit Buyer $1,390.

Scenario 2: Monthly Condominium Contributions

The Scenario: A condo in Edmonton closes on October 20. The monthly condo fees are $450. The seller paid the October condo fee on October 1.

The Calculation:

Period & Amount: Monthly (October has 31 days) / $450.
Per Diem: $450 ÷ 31 days = $14.5161 per day.
Count the Days:
- Seller owns from Oct 1 to Oct 19 = 19 days.
- Buyer owns from Oct 20 to Oct 31 = 12 days.
Financial Share: Buyer's share = 12 days × $14.5161 = $174.19.
Debit/Credit: The seller pre-paid the whole month. The buyer must reimburse the seller for the 12 days they will live there.
Result: Credit Seller $174.19 / Debit Buyer $174.19.

Exam Tips for Proration Questions

When sitting for the broker exam, time management and attention to detail are key. If you are wondering how many questions and the time limit you'll face, know that math questions often consume the most time. To speed up your calculations, memorize the days of the months and always double-check whether the exam specifies a leap year.

Furthermore, ensure you are using the best study materials and resources available in Alberta to practice these exact scenarios. Repetition is the best way to ensure these formulas become second nature before exam day.

Frequently Asked Questions (FAQs)

Who is responsible for property expenses on the Completion Day in Alberta?

Under the standard Alberta Real Estate Association (AREA) Residential Purchase Contract, the buyer is responsible for all property expenses (and entitled to all income) starting at 12:00 AM on the Completion Day. The seller pays up to 11:59 PM the day prior.

Does the Alberta Broker Exam use a 365-day or 360-day year for tax prorations?

Alberta real estate calculations strictly use the exact number of days in a year. Therefore, you must use a 365-day year for standard annual calculations. The 360-day (banker's year) method is not used for standard property tax adjustments in Alberta.

How are leap years handled in RECA exam calculations?

If a question specifically features a date within a leap year (e.g., 2024, 2028), you must account for February having 29 days, making the annual calculation based on a 366-day year. Always read the exam question carefully to see which year is being referenced.

What happens if the current year's property taxes are not yet known at closing?

If a transaction closes early in the year before the municipality has issued the new tax assessment, the lawyers will typically base the proration on the previous year's taxes. They may also apply a holdback or agree to readjust once the final tax bill is issued, though for exam math purposes, you will always be given a specific tax figure to use.

How do prorations appear on the Statement of Adjustments?

Prorations appear as corresponding debits and credits. For example, if a seller pre-paid an annual expense, the unused portion of that expense will appear as a Credit to the Seller (increasing the amount they receive) and a Debit to the Buyer (increasing the amount they must bring to closing).
