Cap Rate Formula for the Florida Real Estate Exam: NOI, Value, and Traps

Cap rate is not hard because of division. Cap rate is hard because the exam surrounds the two useful numbers with distracting ones.

The formula is simple:

Cap rate = NOI / Value

The test-day problem is deciding what belongs in NOI, what counts as value, and what to ignore. Mortgage payment? Ignore it for cap rate NOI. Income taxes? Ignore them. Vacancy loss? Usually part of the income setup. Repairs? Usually operating expense. Down payment? Not part of cap rate.

Use The NOI Fence: only operating income and operating expenses get inside the fence. Financing stays outside.

The Three Cap Rate Formulas

You need three directions:

If the question asks for	Formula
Cap rate	NOI / Value
NOI	Value x Cap rate
Value	NOI / Cap rate

Write the triangle if it helps:

 NOI
Cap Rate | Value

Cover the item you need. The remaining relationship gives the formula.

The NOI Fence

NOI means net operating income. It is not cash flow after debt. It is not profit after income taxes. It is not the owner's spendable cash.

Inside the fence:

• Rental income
• Other operating income
• Vacancy and collection loss
• Property management
• Repairs and maintenance
• Insurance
• Property taxes
• Utilities paid by owner

Outside the fence:

• Mortgage principal and interest
• Down payment
• Debt service
• Depreciation for income-tax accounting
• Owner income taxes
• Capital improvements unless the question treats them differently

The exam can hand you all of these numbers. Your job is not to use them all.

Worked Example: Multi-Step With Vacancy

A property has annual rental income of $96,000, vacancy loss of $6,000, and operating expenses of $32,000. It sells for $800,000. What is the cap rate?

Step 1: Find effective income.

$96,000 - $6,000 = $90,000

Step 2: Find NOI.

$90,000 - $32,000 = $58,000

Step 3: Divide by value.

$58,000 / $800,000 = 0.0725 = 7.25%

Answer: 7.25%.

Worked Example: Find Value

A property has NOI of $72,000. Investors require an 8% cap rate. What is the indicated value?

$72,000 / 0.08 = $900,000

Answer: $900,000.

This is where candidates often multiply by 8 instead of dividing by 0.08. Percent format matters.

Worked Example: Mortgage Distractor

A property has NOI of $60,000 and a value of $750,000. The owner also has a $4,000 monthly mortgage payment. What is the cap rate?

The mortgage payment is a financing distractor. Keep it outside the NOI fence.

$60,000 / $750,000 = 0.08 = 8%

Answer: 8%.

If you subtract the mortgage payment first, you are no longer calculating cap rate from NOI. You are drifting into debt-service or cash-flow thinking.

Worked Example: Find NOI

A property is worth $650,000 at a 7% cap rate. What NOI does that imply?

$650,000 x 0.07 = $45,500

Answer: $45,500.

Cap Rate vs ROI vs Cash-on-Cash

Do not let investment terms blur together.

Term	What it uses	What it answers
Cap rate	NOI and value	Return from the property before financing
ROI	Gain or return compared with investment	Broader investment performance
Cash-on-cash	Cash flow and cash invested	Return on actual cash invested

If the question gives mortgage payments and down payment, it may be testing cash-on-cash or financing, not cap rate. If it gives NOI and value, think cap rate.

The Four Cap Rate Traps

Trap 1: Mortgage payment in NOI

Debt service stays outside the NOI fence.

Trap 2: Gross income instead of NOI

Cap rate uses net operating income, not gross rent.

Trap 3: Percent format

Use 8% as 0.08, not 8.

Trap 4: Wrong value

Use the value the question asks for or gives. Do not substitute loan amount or down payment.

What To Study Next After Cap Rate

Cap rate rarely lives by itself. It sits beside appraisal, income approach, investment analysis, and real estate math. Use this path after you finish this page:

• If you confuse NOI and value, read the income approach guide.
• If the question gives rent but not NOI, review gross rent multiplier.
• If mortgage payments keep sneaking into your answer, review leverage.
• If you want the larger appraisal context, use the income approach guide.
• If mixed formulas are the issue, go to the Florida real estate math formulas guide.

If you understand the NOI fence, the formula itself becomes manageable.

Quick Cap Rate Quiz

Answer these without notes. Score yourself before reading the explanation.

Question 1

NOI is $75,000. Value is $1,250,000. What is the cap rate?

$75,000 / $1,250,000 = 0.06

Answer: 6%.

Question 2

NOI is $90,000. Cap rate is 7.5%. What is the value?

$90,000 / 0.075 = $1,200,000

Answer: $1,200,000.

Question 3

Gross rent is $140,000. Vacancy loss is $10,000. Operating expenses are $52,000. Value is $975,000. What is the cap rate?

$140,000 - $10,000 - $52,000 = $78,000 NOI
$78,000 / $975,000 = 0.08

Answer: 8%.

Question 3 is the version that matters most. The exam can make you build NOI before you ever touch the cap rate formula.

Sanity-Check Cap Rate Answers

Use this quick check when two answer choices both look plausible: for the same NOI, a higher cap rate means a lower indicated value, and a lower cap rate means a higher indicated value.

Example: $80,000 of NOI at 8% supports a $1,000,000 value. The same $80,000 at 10% supports an $800,000 value. If your answer moves in the opposite direction, the formula direction probably flipped.
