Deal math, without the spreadsheet.
The three calculations every off-market deal starts with — running on the same formulas the PropTitan app uses, free, in your browser.
THE SHORT ANSWER
Three free deal calculators that run entirely in your browser: MAO under the 70% rule, ARV from sold-comp price per square foot, and a BRRRR cash-out projection. Each uses the same math the PropTitan app runs on real addresses.
ARV × 70% − rehab
MAO Calculator
Your maximum allowable offer under the 70% rule, plus a conservative opening offer and a walk-away price.
Open calculator →comp $/sqft × your sqft
ARV Calculator
After-repair value from up to three sold comps — a low/mid/high band instead of one guess.
Open calculator →buy → rehab → rent → refi
BRRRR Calculator
Cash left in the deal, monthly cashflow, and equity created after the cash-out refinance.

Typing numbers in by hand gets old
These calculators work on numbers you bring. PropTitan brings the numbers too — sold comps, ARV, rehab estimates, and a full strategy breakdown for any address you paste in.
QUESTIONS
Before you ask
Are these calculators really free?
Yes. No account, no credit card — the math runs in your browser on the numbers you type. Emailing yourself a breakdown is optional.
Is this the same math as the PropTitan app?
Yes — the calculators import the exact same formulas the product’s deal engine uses, from a shared code package. The difference is the app fills the inputs for you from live property data.
Do the calculators store the numbers I enter?
No. Nothing you type leaves your browser unless you choose to email yourself the breakdown, in which case we store your email and the result you asked us to send.
