grouped math tools
Our grouping, not an official state count. Practice the core Subject 10 relationships and selected calculations from finance, closing, valuation, taxes and investment property. Read each tool’s assumptions before using its result.
For exam practice only, not for real transactions. No sign-up needed.
Quick answer
Use these 12 calculators to practice New York real estate exam math. Identify the unknown and its unit, choose a formula, then follow the worked numbers. The collection covers part-rate-whole problems, commissions, value changes, interest, points, specified parcel shapes, acreage, unit prices, LTV, qualifying ratios, prorations, state taxes, NOI, capitalization and GRM. For agency, contracts, fair housing and the other non-math subjects, use the full study guide.
Interactive formula lab
Change any value and the results update immediately. Do the setup on paper first, then use the calculator to check the relationship and arithmetic.
Enter the values stated in the problem. Results update as you type. Money outputs are rounded to cents; calculations retain intermediate precision. The exam still requires you to choose the inputs and formula.
Exam relationship
Work from the sale price to the total commission, then apply each stated share in order. Real-world commission rates are negotiable, so use the rate given in the problem.
Total commission
$25,000.00
Sale price × commission rate
Brokerage share
$12,500.00
Total commission × brokerage share
Salesperson share
$8,750.00
Brokerage share × salesperson share
New York law controls who may receive compensation for licensed activity. This tool teaches the arithmetic only. It does not decide entitlement to a commission.

A four-step math routine
A short written setup makes the base, period, rate and unit easier to inspect. Check those choices before checking the arithmetic.
Write what the question asks for, including its unit.
Mark dollars, percentages, days, feet, square feet, or rates per $100 or $1,000.
Select the formula only after you know the whole, part, rate, period, and base.
Estimate the direction and size before accepting the calculator output.
Go beyond the output

Read the guideNew York exam math FAQ
New York’s salesperson curriculum names percentages, commissions, interest, appreciation, depreciation, points, area including irregular lots, perimeter, acres, hectares, price per square foot, basic mortgage qualifying, real property transfer tax, mortgage recording tax, and real property tax. Calculations also appear in finance, closing, valuation, taxes, and commercial investment topics.
The Department of State candidate guidance permits a battery- or solar-powered, silent, nonprinting calculator without an alphabetic keyboard. Recheck the current appointment and exam-site rules before test day.
No official public subject weighting or scored math-question count is published. The required course assigns one hour to the dedicated Real Estate Mathematics subject, but calculations also appear in several other curriculum subjects. Course hours are not exam weighting.
We grouped the math into 12 tools. That is our grouping, not an official New York State number. The area workspace covers rectangles, right triangles, L-shaped corner cutouts, area conversions and unit prices. The percentage workspace finds a missing part, rate or whole. These tools complement the full study guide; they do not explain every exam subject or model every possible transaction.
No universal commission rate or mortgage qualifying ratio should be assumed. Commission rates are negotiable, and loan standards vary. Use the rate or ratio supplied in the question unless the question clearly asks about a specific published rule.
A proration changes when the closing day is assigned to the seller instead of the buyer. The day-count method matters too. Use the calendar-day or 30-day-month convention and closing-day ownership stated in the problem.
No. They are classroom tools for New York salesperson exam preparation. Real transactions can involve contracts, local rates, exemptions, lender rules, professional judgment, and facts that a short practice calculator does not evaluate.
The calculator topics follow the New York Department of State salesperson curriculum. State tax relationships use current New York tax guidance. Area conversions use federal measurement guidance.
Use the linked sources for the scope and exceptions behind each tax calculation.
The page does not claim an official exam weighting, predict a score, or replace the required 77-hour qualifying course.
