How the Deal Score works

The score weighs 7 factors — profit margin, cash-on-cash ROI, ARV safety margin, holding period, the 70% rule, financing risk, and rehab risk — then applies hard caps so one great number can't hide a real weakness elsewhere. The three Deal Analysis bullets always show whichever factors are actually weakest for your specific numbers, not a fixed set. Read the full breakdown on the blog →

Frequently Asked Questions

Is this fix and flip calculator free to use?
Yes. There's no signup and no limit on how many deals you can run. The Deal Score, Deal Analysis, and 70% rule check are always free; Pro adds deeper comparable-property evidence.
What information do I need to calculate a flip deal score?
Purchase price, rehab budget, after-repair value (ARV), expected holding period, and your financing details (percent financed and interest rate). Holding costs can be adjusted; selling costs use CapShark's fixed 4% realtor and 1% closing assumptions.
Which Canadian cities can I analyze?
The calculator now includes major markets across Ontario, Quebec and Saskatchewan, including Toronto, Ottawa, Hamilton, London, Montréal, Québec City, Laval, Gatineau, Saskatoon and Regina. Canada-wide address matching helps confirm the location, while automated assessment and comparable-property data only appear where a suitable municipal public dataset is available. You must verify local taxes, closing costs and ARV.
Can I save and share my flip deal calculations?
Yes. Deals can be saved locally in your browser for later, shared as a link that restores the exact numbers when opened, or shared as a downloadable deal card image for text, email, or social apps.
How is ROI calculated for a house flip?
Cash-on-cash ROI is net profit divided by the actual cash invested (down payment plus holding costs), not the total deal size. This calculator also shows an annualized ROI, which adjusts for how long the money was tied up.
Does this calculator work outside the US?
Yes, the underlying math (profit, ROI, holding costs, the 70% rule) isn't US-specific. It doesn't account for region-specific transfer taxes or closing cost norms, so verify those with a local professional.
