Mixed closing math calculator, for the questions that stack formulas.
Build one Florida exam-style worksheet with deed stamps, mortgage stamps, intangible tax, commission, and property tax proration.
Mixed closing math is a sorting problem. Label the item, base, rate, side, and final askbefore adding totals. Deed stamps and commission use sale price. Mortgage stamps and intangible tax use loan amount. Proration uses a daily rate and ownership days.
Use the deed rate on the sale price or consideration, rounded up by $100 units.
Use $0.35 per $100 or portion of $100 on the recorded mortgage amount.
Use the exact loan amount. Do not round intangible tax into $100 units.
Commission usually starts with sale price, then may continue into splits.
For unpaid property taxes, the seller commonly credits the buyer for seller days.
Build a closing-math worksheet from one transaction.
This only changes the deed stamp rate. The loan-document rates stay statewide.
Deed stamps use the sale price. Mortgage stamps and intangible tax use the loan amount.
Documentary stamps round up to each $100 or portion of $100. Intangible tax uses the exact loan amount.
Do not combine buyer and seller charges unless the question asks for total transaction math.
A mixed problem may ask for the seller debit, the buyer charge, or the total taxes. Those are three different totals. Solve the pieces, then add only the requested line items.
Add only after every line has a label.
Mixed problems become manageable when you split the scenario into line items. The mistake is adding too early.
Which document controls the tax?
Deed stamps use the deed and sale price. Mortgage or note stamps use the loan amount. Intangible tax also uses the loan amount.
Which party's line items does the question ask for?
Seller debit, buyer charge, total transfer tax, and total transaction math are different totals.
Does the question include Miami-Dade?
If yes, identify whether the deed transfer is single-family or another property type before using the deed rate.
Does the proration item use seller days or buyer days?
Name the item first. Unpaid taxes commonly create a seller credit to buyer for seller-owned days.
Four pieces that show up in mixed closing math.
These examples cover the usual stack: deed stamps, loan taxes, commission, and proration.
$425,450 sale outside Miami-Dade
Round up to $100 units before multiplying.
$340,000 mortgage
Mortgage stamps and intangible tax are separate calculations.
$425,450 sale at 6 percent
Do not use loan amount for commission.
$4,380 annual taxes, 196 seller days
Unpaid taxes usually credit the buyer for seller-owned days.
Why mixed closing questions feel harder than the individual formulas.
Each formula is familiar by itself. The challenge is choosing the right base, side, and total when they appear together.
Using sale price for every calculation
Deed stamps use sale price. Mortgage stamps and intangible tax use the loan amount. Commission uses sale price.
Rounding intangible tax like documentary stamps
Documentary stamps round up by $100 units. Intangible tax is a straight loan amount x 0.002 calculation.
Adding buyer and seller charges when only one side is asked
A closing statement question may ask for one party's debit or credit, not the combined transaction total.
Using the standard deed rate in Miami-Dade
Miami-Dade deed rates depend on property type. Single-family and non-single-family transfers are tested differently.
Calculating the right amount for the wrong side
Proration requires both amount and direction. Decide whether it is unpaid, prepaid, or collected ahead before adding it.
Isolate each piece before drilling mixed sets.
If this worksheet feels crowded, study each linked calculator separately, then come back and combine them.
What is mixed closing math on the Florida real estate exam?+
Mixed closing math combines more than one formula in the same transaction. A question may include documentary stamps, intangible tax, commission, property tax proration, and a final ask about buyer charges, seller debits, or total taxes.
What is the biggest mixed closing math trap?+
The biggest trap is using the same base for every line item. Deed stamps and commission use sale price. Mortgage stamps and intangible tax use loan amount. Proration uses time and daily rate.
Should I add buyer and seller costs together?+
Only if the question asks for a combined total. If it asks for the seller's debit, buyer's charge, or one side's closing statement entry, add only the relevant line items.
How do I avoid losing track in a mixed problem?+
Make a mini worksheet with columns for item, base, rate, side, and result. Solve each piece separately before adding anything.
Is this calculator a live closing estimate?+
No. It is built for Florida real estate exam preparation. Real closings include contract terms, title-company practices, county recording details, lender charges, exemptions, and legal facts.
A Broward property sells for $450,000 with a $360,000 mortgage. What is the total of deed stamps, mortgage stamps, and intangible tax?
Deed stamps: 4,500 x $0.70 = $3,150. Mortgage stamps: 3,600 x $0.35 = $1,260. Intangible tax: $360,000 x 0.002 = $720. Total: $5,130.
