What kind of deals does the calculator handle?

It runs the numbers for fix-and-flip and renovation projects, including rehab, holding, purchase, and exit costs, ARV, projected profit, ROI, and annualized return.

Q: Does it include holding and exit costs?

Yes. The calculator includes purchase costs, holding costs (property tax, insurance, utilities, staging, photos, cleaning), and exit costs (transfer fees, closing, and agent commissions) so your projected profit reflects the real all-in cost.

Q: Can I split the profit with partners?

Yes. You can add partners to split the projected profit with investors or a JV, so everyone sees their share before the deal closes.

Q: Where does the ARV come from?

You ground after-repair value in the comp set you build from the listings you're viewing, so the calculator works from real, recent sales instead of a guess.

What it calculates

Every number that decides a deal

No more rebuilding the same spreadsheet. Every number a deal depends on is built in and updates as you type.

Returns & profit

Projected profit, ROI, annualized return, and return on cash invested — plus a target profit so you can see how close a deal is to your goal at a glance.

Every cost, automatic

Purchase, holding, and exit costs all in one place: transfer fees, closing costs, agent commissions, property tax, insurance, utilities, staging, photos, and cleaning.

Financing & strategy

Loan interest, points, fees, and loan-to-value — with roll-into-loan options — across fix-and-flip and renovation projects.

Not a guess

Grounded in your comps

The calculator pulls your after-repair value from the comp set you build out of the listings you're already viewing — so your numbers stand on real, recent sales, not a round number you typed in.
