Step-by-Step Proration Calculations for the Alberta Real Estate Exam
Last updated: April 2026
If you are preparing for your real estate licensing in Alberta, you will inevitably encounter math questions on the Real Estate Council of Alberta (RECA) exams. One of the most critical mathematical concepts you must master is the calculation of prorations (also known as adjustments). Whether you are dealing with property taxes, condominium contributions, or monthly rent, understanding how to fairly divide these costs between a buyer and a seller is a fundamental skill for any real estate professional.
Before diving into the math, ensure you have reviewed our Complete Alberta Real Estate Associate Exam Exam Guide for a holistic view of your study path. In this article, we will walk you through proration calculations step by step, precisely as they are tested on the Alberta exam.
Understanding Proration in Alberta Real Estate
Proration is the process of proportionally dividing financial responsibilities between the buyer and the seller as of the closing date, which in Alberta is officially referred to as the Completion Day. These calculations ensure that the seller only pays for the property expenses during the time they owned it, and the buyer assumes responsibility the moment they take possession.
On the RECA exam, you will typically be asked to calculate adjustments for:
- Property Taxes: Billed annually by the municipality (e.g., the City of Calgary or Edmonton).
- Condominium Fees: Billed monthly by the condo corporation.
- Rental Income: Collected monthly if the property is tenanted.
The Golden Rule of Alberta Adjustments
To pass the proration questions on the exam, you must memorize the standard clause found in the Alberta Real Estate Association (AREA) Residential Purchase Contract regarding the Completion Day.
The Alberta Rule: The buyer is responsible for the property (and its associated costs) on the Completion Day. Therefore, the seller's period of responsibility ends on the day prior to the Completion Day.
For example, if the Completion Day is September 15th:
- The Seller pays for the property from January 1st up to and including September 14th.
- The Buyer pays for the property starting September 15th through to December 31st.
Step-by-Step Proration Calculation Method
When you encounter an adjustment question on your exam, follow this foolproof five-step method:
Step 1: Identify the Billing Period and the Total Amount
Determine if the expense is annual (like property taxes) or monthly (like condo fees), and note the total amount billed for that period.
Step 2: Determine the Daily Rate
Divide the total amount by the exact number of days in the billing period. For annual taxes in a standard year, divide by 365. For a monthly fee, divide by the exact number of days in that specific month (e.g., 31 days for October, 30 days for November).
Step 3: Establish the Completion Day
Identify the exact date the property changes hands. Remember the Alberta Rule: the buyer owns the Completion Day.
Step 4: Count the Days
Count the exact number of days the buyer is responsible for (if the bill was paid in advance by the seller) or the exact number of days the seller is responsible for (if the bill is to be paid in arrears by the buyer). Tip: Use your knuckles to remember which months have 31 days!
Step 5: Calculate and Assign the Adjustment
Multiply the daily rate by the number of days. Finally, determine who owes whom. If the seller pre-paid the whole year, the buyer must reimburse the seller for the buyer's days (Credit Seller, Debit Buyer).
Practical Exam Scenarios
Let's apply this method to the types of questions you will see on the RECA exam.
Scenario 1: Property Taxes Paid in Advance
Question: A property in Red Deer has an annual property tax bill of $3,650, which the seller has already paid in full for the year. The Completion Day is set for August 15th. Assume a non-leap year (365 days). What is the adjustment on the Statement of Adjustments?
- Period & Amount: Annual, $3,650.
- Daily Rate: $3,650 ÷ 365 days = $10.00 per day.
- Completion Day: August 15th.
- Count the Days: Because the seller paid the whole year in advance, the buyer owes the seller for the days the buyer owns the home (Aug 15 to Dec 31).
- August: 17 days (31 - 15 + 1)
- September: 30 days
- October: 31 days
- November: 30 days
- December: 31 days
- Total Buyer Days: 139 days
- Calculate: 139 days × $10.00/day = $1,390.00.
Answer: The buyer must reimburse the seller. The adjustment is a Credit to the Seller of $1,390 and a Debit to the Buyer of $1,390.
Day Allocation for August 15 Completion Day
Scenario 2: Monthly Condo Fees Paid in Advance
Question: The monthly condominium contributions for a Calgary apartment are $450. The seller pays this on the 1st of every month. The Completion Day is October 20th. Calculate the adjustment.
- Period & Amount: Monthly (October), $450.
- Daily Rate: October has 31 days. $450 ÷ 31 = $14.5161... per day. (Keep all decimal places in your calculator until the final step!)
- Completion Day: October 20th.
- Count the Days: The buyer owns the property from October 20th to October 31st.
- 31 - 20 + 1 = 12 days.
- Calculate: 12 days × $14.5161... = $174.1935...
Answer: Rounded to the nearest cent, the adjustment is a Credit to the Seller of $174.19 and a Debit to the Buyer of $174.19.

Frequently Asked Questions (FAQs)
1. Who is responsible for the property 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 (taxes, utilities, condo fees) starting on the actual Completion Day.
2. How are leap years handled on the RECA exam?
Unless the exam question specifically states it is a leap year, you should assume a standard 365-day year for annual calculations. If a leap year is specified, you must divide the annual amount by 366 and ensure February is counted as 29 days.
3. What does it mean if property taxes are paid "in arrears"?
Paid in arrears means the bill is paid at the end of the billing period rather than the beginning. If taxes are paid in arrears, the seller has not yet paid for their portion of the year. Therefore, on closing, the seller must give the buyer a credit for the days the seller owned the property, as the buyer will be stuck paying the full bill later.
4. Do I round my numbers during the calculation steps?
No. A common mistake on the RECA exam is rounding the daily rate to two decimal places before multiplying by the number of days. This can lead to an incorrect final answer. Keep the long decimal in your calculator and only round to the nearest cent ($0.01) at the very final step.
5. How do we calculate rent adjustments if the property has a tenant?
Rent is typically paid to the seller in advance on the 1st of the month. Because the buyer owns the property on the Completion Day, the seller must transfer the rent for the buyer's days over to the buyer. Additionally, the seller must transfer the tenant's full security deposit (plus any required accrued interest) to the buyer, as the buyer will be responsible for returning it when the tenant eventually moves out.
