Real estate investing calculators

Free calculators for the numbers investors run on every deal: cash flow, cap rate, yield, mortgage payment, fix-and-flip profit, BRRRR, the 70% rule, wholesale fees, and Texas and Oklahoma property tax. Each one shows its formula and a worked example.

Cash flow and cap rate

Calculate monthly cash flow, cap rate, NOI, cash-on-cash return and DSCR for a rental property, with the formulas and a worked example.

Rental yield

Calculate gross and net rental yield from purchase price, rent and expenses, with the formulas, a worked example and how yield differs from cap rate.

Mortgage payment

Estimate a monthly mortgage payment including principal, interest, property tax, insurance, PMI and HOA, with the amortization formula and a worked example.

Fix and flip

Estimate fix-and-flip profit, cash needed and ROI from purchase price, rehab budget, holding costs, loan terms and ARV, with a worked example.

BRRRR

Run a BRRRR deal (buy, rehab, rent, refinance, repeat): all-in cost, refinance loan, cash left in the deal, cash flow and cash-on-cash return.

70% rule

Find the maximum offer on a fix-and-flip using the 70% rule: ARV times 70% minus repairs. Adjust the percentage and see a worked example.

Wholesale fee

Estimate the maximum wholesale assignment fee: the end buyer's maximum price (ARV x rule % - repairs) minus your contract price, less your costs.

TX and OK property tax

Estimate yearly property tax in Texas (rates per $100, $140,000 school homestead exemption) or Oklahoma (assessment ratio, $1,000 homestead exemption, millage).
