Oklahoma Real Estate Math
Practice Questions & Answers (2026)
Real estate math questions appear on every Oklahoma real estate exam and test a focused set of calculations: commission splits, prorations (property tax, rent, interest), loan-to-value ratios, appreciation and depreciation, and area calculations. The Oklahoma Real Estate Commission (OREC) does not provide a calculator — but the math is designed to be workable without one if you know the right formulas. Oklahoma candidates consistently lose points on proration questions because they apply the wrong day-count convention (360-day vs. 365-day year) or miscalculate the seller's vs. buyer's share. Work through every problem in this section until you can solve each type without hesitation.

Q1. A home sells for $275,000. The total commission is 6%, split equally between the listing broker and the buyer's broker. The listing agent earns 60% of their broker's share. How much does the listing agent earn?
Explanation
Total commission: $275,000 × 0.06 = $16,500. Listing broker's share: $16,500 ÷ 2 = $8,250. Listing agent's share: $8,250 × 0.60 = $4,950.
Q2. A buyer wants to borrow $240,000 at 7% annual interest on a 30-year mortgage. What is the monthly interest due for the first month?
Explanation
Monthly interest = Loan balance × (annual rate ÷ 12). $240,000 × (0.07 ÷ 12) = $240,000 × 0.005833 = $1,400. This is the interest portion of the first month's payment; the remainder of the monthly payment reduces principal.
Q3. A seller lists a property at $320,000 and agrees to pay a 5.5% commission. The property sells for $305,000. How much commission is paid?
Explanation
Commission is based on the actual sale price, not the list price. $305,000 × 0.055 = $16,775.
Q4. A property is assessed at 11% of its market value of $400,000. The mill rate is 85 mills. What is the annual property tax?
Explanation
Assessed value: $400,000 × 0.11 = $44,000. Annual tax: $44,000 × (85 ÷ 1,000) = $44,000 × 0.085 = $3,740. One mill equals $1 per $1,000 of assessed value.
Q5. A buyer purchases a home for $185,000 with a 10% down payment. What is the loan amount?
Explanation
Down payment: $185,000 × 10% = $18,500. Loan amount: $185,000 − $18,500 = $166,500.
Q6. A property's net operating income is $36,000 per year. If the cap rate is 8%, what is the estimated value?
Explanation
Value = NOI ÷ Cap Rate. $36,000 ÷ 0.08 = $450,000.
Q7. A rectangular lot measures 150 feet wide by 200 feet deep. How many square feet does it contain?
Explanation
Area = Length × Width. 150 × 200 = 30,000 square feet.
Q8. A 30,000 square foot lot is what fraction of an acre? (1 acre = 43,560 sq ft)
Explanation
Acres = Square feet ÷ 43,560. 30,000 ÷ 43,560 = 0.689, approximately 0.69 acres.
Q9. A seller wants to net $210,000 after paying a 6% commission. At what price must the home sell?
Explanation
Net proceeds = Sale price × (1 − commission rate). $210,000 = Sale price × 0.94. Sale price = $210,000 ÷ 0.94 = $223,404.26, approximately $223,617 is not correct — Sale price = $210,000 ÷ 0.94 = $223,404.26. The closest answer is $223,404.
Q10. A property sells for $350,000 today. The seller originally paid $220,000. What is the percentage of appreciation?
Explanation
Appreciation % = (Sale price − Purchase price) ÷ Purchase price × 100. ($350,000 − $220,000) ÷ $220,000 × 100 = $130,000 ÷ $220,000 × 100 = 59.1%.
Q11. If a lender requires a maximum DTI of 43% and the borrower's gross monthly income is $6,500, what is the maximum total monthly debt payment allowed?
