Remember, this is profit before tax. Profits from flips are generally taxed as ordinary business income rather than long-term capital gains, so what you keep can be meaningfully lower. It's worth planning for before you spend or reinvest the proceeds.

This calculator gives a quick, high-level estimate for planning purposes only and is not tax or investment advice. The 70% rule is a common rule of thumb, not a guarantee. Actual results depend on market conditions, project costs, financing, and your tax situation.
