If you're preparing for a real‑estate license, you've already covered laws, mortgages, and sales tactics. The final piece of the puzzle is mastering the math that powers every transaction.
Start by memorizing key terms and formulas for calculating size. Area is length × width and is expressed in square units—square feet for typical listings or acres for larger parcels. Remember that 1 acre = 43,560 sq ft, 1 yard = 3 ft, so 1 sq yd = 9 sq ft.
All loan agreements accrue interest. The classic formula I = P × R × T (interest = principal × rate × term) lets you compute annual interest, monthly payments, or total interest over a loan’s life. Mastering this equation equips you to explain loan structures to clients.
Percentages are parts per hundred; as decimals they simplify calculations. For example, an 8 % interest rate is 0.08, so the yearly interest on a $200,000 loan is $200,000 × 0.08 = $16,000. A 3 % commission on a $150,000 sale equals $150,000 × 0.03 = $4,500. Prorations and taxes follow the same logic: a seller who prepaid a $12,000 annual condo fee and is selling after three months receives a 75 % refund (9/12) of that fee, calculated as $12,000 × 0.75. A 1 % transfer tax on a $250,000 property is $250,000 × 0.01 = $2,500.
More advanced problems—such as appraisals, depreciation, or contingency calculations—often involve the same arithmetic tools: multiplication, fractions, decimals, and percentages. Breaking the problem into sequential steps ensures accuracy and reduces errors.
