🏠 Real Estate Salesperson — printable formula & quick-reference card
Real estate math formulas are industry-standard and appear on state exams in a similar form everywhere.
- Commission
- Commission = Sale Price × Commission Rate
- Rate
- Rate = Commission ÷ Sale Price
- Example
- $300,000 × 3% = $9,000
- Split
- Agent’s share = Commission × Agent’s split %
- Loan-to-value (LTV)
- LTV % = Loan Amount ÷ Appraised Value
- Example
- $200,000 loan ÷ $250,000 value = 80%
- Annual interest
- Annual Interest = Principal × Annual Rate
- Monthly interest
- Monthly = (Principal × Rate) ÷ 12
- 1 acre
- 43,560 square feet
- 1 square mile
- 640 acres
- Price per square foot
- Price ÷ Total Square Feet
- Acres
- Square Feet ÷ 43,560
- Percentage
- Part = Total × Rate · Rate = Part ÷ Total
- Daily proration
- Daily Amount = Annual Amount ÷ 365
- Prorated total
- Daily Amount × Days in the period
- Rule of thumb
- Convert every unit to a common unit before multiplying
