Florida Real Estate Exam Math: Every Formula You Need to Know

Math questions show up on almost every Florida Real Estate Sales Associate exam. They are not optional, and they are not hard to prepare for, but only if you know which formulas to memorize. This post covers every calculation category tested by Pearson VUE under the DBPR and FREC licensing framework, with worked examples for each one.

Prorations

Proration questions appear constantly. The exam will give you a closing date and ask you to split a prepaid or past-due expense between buyer and seller.

Florida licensing exam practice problems commonly use a 30-day month and 360-day year (the banker's year). If the exam question instructs you to use actual calendar days, follow those instructions instead.

Worked Example

Annual property taxes are $2,160. Closing is March 15. The seller owes taxes from January 1 through March 15. How much does the seller owe at closing?

• Daily rate: $2,160 ÷ 360 = $6.00 per day
• Days charged: January (30) + February (30) + 15 days in March = 75 days
• Seller's share: 75 × $6.00 = $450 credit to buyer

The seller is debited $450 and the buyer is credited $450 on the closing statement. If you get confused about debits and credits, check the glossary for definitions.

Documentary Stamp Taxes

Florida imposes documentary stamp taxes on deeds and on promissory notes or mortgages.

• On the deed (sales price): $0.70 per $100, or any portion thereof
• On the mortgage (loan amount): $0.35 per $100, or any portion thereof
• Miami-Dade County: Different documentary stamp tax rules apply, and a documentary surtax may be charged depending on the type of property and transaction.

Worked Example

A property sells for $285,000 with a new mortgage of $228,000. What are the documentary stamp taxes outside Miami-Dade?

• Doc stamps on deed: $285,000 ÷ 100 = 2,850 units × $0.70 = $1,995.00
• Doc stamps on mortgage: $228,000 ÷ 100 = 2,280 units × $0.35 = $798.00

Always round up to the next $100 if the price does not divide evenly.

Intangible Tax

Although documentary stamp taxes are tested more frequently, candidates should also know Florida's nonrecurring intangible tax on new mortgages (2 mills, or $0.002 per $1), as it may appear on the licensing exam. It applies to new obligations secured by Florida real property, not to assumptions or refinances of existing Florida mortgages.

Worked Example

New mortgage: $228,000. Intangible tax = $228,000 × 0.002 = $456.00

This is paid by the borrower at closing and is separate from documentary stamps.

Loan-to-Value Ratio (LTV)

LTV = Loan Amount ÷ Appraised Value (or Sales Price, whichever is lower)

Worked Example

Purchase price is $300,000. Down payment is $45,000. LTV = $255,000 ÷ $300,000 = 85%

Lenders use LTV to determine whether private mortgage insurance is required. Conventional loans above 80% LTV typically require PMI.

Capitalization Rate (Cap Rate)

Cap rate is used to evaluate income-producing properties.

Cap Rate = Net Operating Income ÷ Value

You can rearrange this to solve for value or NOI depending on what the question asks.

Worked Example

A small apartment building generates $42,000 NOI per year. Similar properties sell at an 8% cap rate. What is the estimated value?

• Value = NOI ÷ Cap Rate
• Value = $42,000 ÷ 0.08 = $525,000

Gross Rent Multiplier (GRM)

GRM = Sales Price ÷ Gross Annual Rent

GRM is a quick comparison tool, not as precise as cap rate because it ignores expenses.

Worked Example

A duplex sells for $310,000 and generates $26,000 in annual gross rent. GRM = $310,000 ÷ $26,000 = 11.9

To estimate value using a known GRM: Value = GRM × Gross Annual Rent.

Commission Calculations

These questions often involve splits between brokers and between broker and sales associate.

Worked Example

A property sells for $415,000. Total commission is 6%. The listing and selling brokers split equally. The selling sales associate receives 60% of their broker's share. How much does the sales associate earn?

• Total commission: $415,000 × 0.06 = $24,900
• Each broker's share: $24,900 ÷ 2 = $12,450
• Sales associate's share: $12,450 × 0.60 = $7,470

Under Chapter 475, Florida Statutes, a sales associate can only receive compensation through their employing broker, never directly from a buyer or seller.

Putting It All Together

The math section of the Florida Real Estate Sales Associate exam is manageable when you practice each formula type in isolation first, then work mixed problems. The exam delivered through Pearson VUE includes a basic calculator on screen, so your job is to know which formula to apply, not to do arithmetic in your head.

Review the full formula sheet to make sure you have every rate memorized, then test yourself with practice questions that mirror the real exam format. If you want to see how math fits into the broader exam structure, the 19 exam topics breakdown is a good next read.
