QUICK ANSWER
Build monthly PITI first: principal and interest, monthly taxes, monthly insurance, and any payment items the stem includes. Then divide by gross monthly income for the front-end ratio, or add other monthly debts first for the back-end ratio. Keep both sides monthly.
EXAM PREP ONLY
This post explains how this topic appears on the Florida real estate sales associate exam. It is not legal, tax, lending, appraisal, brokerage, title, insurance, closing, or professional advice. For a real transaction or real-world decision, verify current requirements with the official source or consult a qualified licensed Florida professional.
PITI questions do not usually beat candidates because the arithmetic is hard. They beat candidates because the stem quietly switches time periods. Monthly income, annual taxes, annual insurance, monthly debt, and principal-and-interest payments all land in one paragraph.
On the Florida sales associate exam, PITI is a setup test. Florida Administrative Code Rule 61J2-2.029 assigns 10 points of the sales associate examination to real estate mathematics. PITI can sit inside that math pool, but it also touches lending vocabulary, so the exam-safe move is to use only the numbers and ratios the stem gives you.
The question underneath the question is simple: "Which monthly payment number am I supposed to build before I divide?"
If you already know PITI but keep mixing it with LTV, use the LTV trap guide after this. If your miss is broader mortgage vocabulary, use the mortgages and lending guide.
What PITI Means On The Exam
PITI stands for:
- Principal
- Interest
- Taxes
- Insurance
The Consumer Financial Protection Bureau describes PITI as the four basic elements of a monthly mortgage payment. In exam math, treat it as a monthly stack.
The principal and interest part may be given directly, or the stem may give a payment factor. Taxes and insurance are often stated annually, which means you usually divide each by 12 before adding them to the monthly payment.
Do not treat PITI as the same thing as LTV. PITI is monthly payment math. LTV is loan amount compared to property value. Both can appear in the same lending stem, which is exactly why students mix them.
The Monthly PITI Stack
The Monthly PITI Stack is the habit of building the monthly payment in layers before using it in a ratio.
Use this order:
- Find monthly principal and interest.
- Convert annual property taxes to monthly taxes.
- Convert annual insurance to monthly insurance.
- Add mortgage insurance, HOA dues, or other payment items only when the stem gives them.
- Use the finished monthly PITI in the qualifying ratio the question asks for.
The stack protects you from two common misses. One miss is stopping at principal and interest when the question asks for full PITI. The other is using annual taxes or insurance as if they were monthly numbers.
Step 1: Find Monthly Principal And Interest
If the question gives the monthly principal-and-interest payment, use it. Do not recalculate.
If the question gives a payment factor per $1,000 of loan amount, use the factor like this:
Loan amount / 1,000 = number of thousands
Number of thousands x payment factor = monthly principal and interest
Before you calculate, write a quick scratchpad:
Find: ______
Given: ______
Ignore: ______
Operation: ______
Estimate: ______
This is the one useful habit worth salvaging from the older PITI page. It slows the first move just enough to keep annual numbers, monthly numbers, and distractors in separate lanes.
Worked example:
A buyer obtains a $280,000 loan. The monthly principal-and-interest payment is $6.65 per $1,000 borrowed. What is the monthly principal and interest?
Step 1: Convert the loan amount into thousands.
$280,000 / 1,000 = 280
Step 2: Multiply by the payment factor.
280 x $6.65 = $1,862
Answer: $1,862
The trap is multiplying $280,000 x $6.65, which creates an absurd payment. The phrase "per $1,000" is not decoration. It tells you to shrink the loan amount before multiplying.
Step 2: Build The Full Monthly PITI
Once principal and interest are known, build the full monthly payment.
Worked example:
A buyer's monthly principal and interest is $1,862. Annual property taxes are $4,200. Annual homeowner's insurance is $1,800. Monthly mortgage insurance is $110. What is the monthly PITI?
Step 1: Convert annual taxes to monthly.
$4,200 / 12 = $350
Step 2: Convert annual insurance to monthly.
$1,800 / 12 = $150
Step 3: Stack the monthly items.
$1,862 + $350 + $150 + $110 = $2,472
Answer: $2,472
The annual-to-monthly conversion is often the whole trap. If the answer choices include one large number and one clean monthly number, check whether one answer used annual taxes or insurance without dividing by 12.
Step 3: Apply The Front-End Ratio
The front-end qualifying ratio compares the monthly housing payment to gross monthly income.
Use this setup:
Front-end ratio = monthly PITI / gross monthly income
Worked example:
A buyer has gross monthly income of $8,000. Monthly PITI is $2,240. What is the front-end ratio?
$2,240 / $8,000 = 0.28
0.28 x 100 = 28%
Answer: 28%
The front-end ratio does not add the buyer's car payment, credit card payment, or student loan payment. Those belong in the back-end ratio.
Step 4: Apply The Back-End Ratio
The back-end qualifying ratio adds other monthly debts to PITI before dividing by gross monthly income.
Use this setup:
Back-end ratio = (monthly PITI + other monthly debts) / gross monthly income
Worked example:
A buyer has gross monthly income of $8,000, monthly PITI of $2,240, and other monthly debts of $560. What is the back-end ratio?
($2,240 + $560) / $8,000 = $2,800 / $8,000
$2,800 / $8,000 = 0.35
0.35 x 100 = 35%
Answer: 35%
The same stem can produce both 28% and 35%. Both are real. Only one answers the question being asked.
When A Ratio Limit Appears
Sometimes the stem gives a qualifying limit, such as a maximum housing-expense ratio. Use the limit the stem provides. Do not import a real-world underwriting rule from memory.
Worked example:
A buyer has gross monthly income of $7,500. The lender uses a 28% housing-expense limit in the question. What is the maximum monthly PITI allowed under that limit?
$7,500 x 0.28 = $2,100
Answer: $2,100
If the actual monthly PITI in the stem is $2,240, the buyer is over that specific limit by:
$2,240 - $2,100 = $140
This is not a prediction about real loan approval. It is exam math. Use the ratio and facts the question gives you.
The math itself only needs four-function arithmetic. Before exam day, verify the current calculator rules on Pearson VUE's Florida real estate page, then practice with the same basic calculator habit you plan to use under time pressure.
Keep The Time Periods Matched
PITI questions are monthly unless the stem tells you otherwise. That means annual amounts need to become monthly amounts before they enter the stack.
Use this table when the numbers feel crowded:
| Fact in the stem | What to do before using it | Why |
|---|---|---|
| Monthly principal and interest | Use as monthly | Already in the right period |
| Payment factor per $1,000 | Multiply by loan thousands | Builds monthly P&I |
| Annual taxes | Divide by 12 | PITI is monthly |
| Annual insurance | Divide by 12 | PITI is monthly |
| Monthly mortgage insurance | Add as monthly | Already in the right period |
| Gross monthly income | Use as monthly denominator | Matches monthly debts |
| Annual income | Divide by 12 before ratios | Ratios use monthly income |
If you remember only one rule from this section, remember this: monthly numerator, monthly denominator.
Read The Wrong Answers
The wrong answers in PITI questions are usually not random. They show which layer of the stack failed.
| Wrong answer pattern | What probably happened | Repair |
|---|---|---|
| P&I-only answer | Stopped before adding taxes and insurance | Finish the PITI stack |
| Huge payment | Used annual taxes or insurance as monthly | Divide annual amounts by 12 |
| Tiny ratio | Used annual income as denominator | Convert income to monthly |
| Front-end answer on back-end question | Forgot other monthly debts | Add debts for back-end only |
| Back-end answer on front-end question | Added debts too early | Use PITI alone for front-end |
| Loan-value answer | Solved LTV instead of PITI | Identify monthly payment versus property value |
| Payment factor answer too large | Multiplied factor by full loan amount | Use loan amount per $1,000 |
This table is the Trap Library habit in miniature: catalog the mistake that produced each wrong answer, not just the correct choice. Do not only ask whether the answer is wrong. Ask which mistake produced it.
A Five-Question Practice Loop
Try these before opening the answer. The goal is not speed yet. The goal is clean setup.
Practice 1: Principal And Interest
A buyer borrows $240,000. The monthly payment factor is $6.90 per $1,000 borrowed. What is the monthly principal and interest?
Show answer
Answer: $1,656. Convert the loan to thousands: $240,000 / 1,000 = 240. Then multiply: 240 x $6.90 = $1,656.
The trap is multiplying $240,000 by $6.90.
Practice 2: Full PITI
Monthly principal and interest is $1,656. Annual taxes are $3,600. Annual insurance is $1,440. What is monthly PITI?
Show answer
Answer: $2,076. Taxes: $3,600 / 12 = $300. Insurance: $1,440 / 12 = $120. PITI = $1,656 + $300 + $120 = $2,076.
The trap is forgetting that taxes and insurance were annual.
Practice 3: Front-End Ratio
A buyer has gross monthly income of $7,200 and monthly PITI of $2,016. What is the front-end ratio?
Show answer
Answer: 28%. $2,016 / $7,200 = 0.28, which is 28%.
The trap is adding other debts when the question asks for the front-end ratio.
Practice 4: Back-End Ratio
A buyer has gross monthly income of $7,200, monthly PITI of $2,016, and other monthly debts of $504. What is the back-end ratio?
Show answer
Answer: 35%. Add PITI and other debts first: $2,016 + $504 = $2,520. Then divide by income: $2,520 / $7,200 = 0.35, or 35%.
The trap is using the front-end ratio when the question asks for total debt.
Practice 5: Maximum PITI
A buyer has gross monthly income of $6,500. The question gives a maximum housing-expense ratio of 28%. What is the maximum monthly PITI under that limit?
Show answer
Answer: $1,820. $6,500 x 0.28 = $1,820.
The trap is dividing by 28 or using 28 instead of 0.28.
Score check: 5/5 means the PITI setup is ready for mixed math practice. 4/5 means review the one layer you missed. 3/5 or lower means redo this post with scratch paper before mixing it with LTV or proration.
After the setup is clean, use the Mortgage Qualifying Ratios Calculator to check your arithmetic. Use the calculator after you choose front-end or back-end, not before.

Exam-Style Question
A buyer has gross monthly income of $7,500. Monthly principal and interest is $1,680. Annual property taxes are $4,800. Annual homeowner's insurance is $1,200. Other monthly debts are $420. What is the buyer's front-end qualifying ratio?
A. 22.4%
B. 29.1%
C. 34.7%
D. 27.7%
Show answer
Correct answer: B. First build monthly PITI. Taxes are $4,800 / 12 = $400. Insurance is $1,200 / 12 = $100. PITI is $1,680 + $400 + $100 = $2,180. Front-end ratio is $2,180 / $7,500 = 0.2907, or about 29.1%.
Option A uses principal and interest only. Option C is the back-end ratio because it adds the $420 other monthly debts. Option D includes taxes but omits insurance. The word "front-end" tells you to use PITI, not all monthly debt.
FAQ
What does PITI stand for on the real estate exam?
PITI stands for principal, interest, taxes, and insurance. On the exam, it is usually a monthly housing-payment number.
How do I calculate monthly principal and interest?
Use the number the stem gives. If the question gives a payment factor per $1,000 borrowed, divide the loan amount by 1,000, then multiply by the factor.
Do I divide property taxes and insurance by 12?
Yes, when the question gives annual taxes or annual insurance and asks for monthly PITI. PITI and qualifying ratios are monthly calculations unless the stem says otherwise.
Is mortgage insurance included in PITI?
Use mortgage insurance when the stem includes it as part of the monthly payment. Do not invent mortgage insurance if the question does not provide it.
What is the front-end ratio?
The front-end ratio compares monthly PITI to gross monthly income. It does not include the buyer's other monthly debts.
What is the back-end ratio?
The back-end ratio compares total monthly debt to gross monthly income. Add PITI plus other monthly debts before dividing by gross monthly income.
Is PITI the same as DTI?
No. PITI is the monthly housing payment. DTI is a ratio that compares monthly debt payments to gross monthly income.
Does Pass Florida replace the 63-hour course?
No. Pass Florida is exam preparation only. It does not replace the 63-hour pre-license course, DBPR processes, Pearson VUE scheduling, or legal, tax, lending, appraisal, brokerage, title, closing, or professional advice.
READY FOR MIXED MATH?
You just built the PITI stack. Now practice it when the topic label disappears.
The Florida sales associate exam can mix PITI with LTV, proration, millage, and commission in the same study session. Math Coach drills those setup switches, and Trap Library names the mistake behind each miss. Pass Florida is $39.99 once, with no subscription and no copied state exam questions.
