Flip Calculators
Website-ready calculators for investors, flippers, landlords, and wholesalers. Start with the expected resale price or rent and work backward to determine a maximum purchase price that still leaves room for costs and profit.
How to Use These Calculators
These tools are designed to help investors quickly evaluate flips and rentals. Start with your best estimate of resale value or rent, then adjust the assumptions until the numbers reflect the deal you are actually considering.
Max Purchase Calculator
ARV is the expected sale price after repairs. This is often based on rehabbed comparable sales.
Rehab Costs should include labor, materials, permits, and contractor overhead if applicable.
Selling Costs usually include commissions and seller closing costs.
Holding Period is the time from purchase to resale. Include enough time for rehab, listing, contract, and closing.
Monthly Carrying Costs typically include taxes, insurance, utilities, lawn care, snow removal, and other ownership costs during the hold.
Financing Costs may include points, interest, lender fees, and draw fees.
Desired Profit can be entered as a fixed dollar amount or a percentage of ARV.
Contingency is your extra safety buffer for unexpected repairs or overruns.

This version separates more assumptions so you can see how commissions, seller closing costs, carrying costs, financing, and rehab overruns affect your maximum price.
Agent Commission is typically the total commission paid at resale.
Seller Closing Costs are non-commission closing expenses at the sale side.
Repair Overrun Buffer adds a cushion on top of the base rehab estimate.
Loan-to-Cost, Interest Rate, and Points are used to estimate financing costs if financing is included.
