The formula

Know exactly what the calculator is doing.

Projected profit = ARV - purchase - repairs - buying costs - financing - holding costs - selling costs

The result keeps every major cost visible instead of assuming the 30% spread in the 70% rule will cover everything.

A durable workflow

Use the result as a decision aid, not a verdict.

Enter a supported ARV

Use comparable renovated sales and explain every adjustment.

Price the full project

Include repair contingency, financing, ownership, and sale costs.

Compare profit with your target

A positive profit is not automatically an acceptable risk-adjusted return.

Important limits

What this calculation cannot know.

ARV is an opinion until supported by relevant sold comparables.
The calculator does not estimate income tax, entity tax, or property-specific legal obligations.
Timeline changes should update both financing and holding costs.

Common questions

Understand the terms before using the output.

How is house flip profit calculated?

Subtract the purchase, renovation, buying, financing, holding, and selling costs from the expected sale price.

What is a good ROI on a house flip?

There is no universal target. Required return depends on project risk, time, leverage, liquidity, and the operator's alternatives.

Does this include the 70% rule?

The detailed maximum purchase output solves for the price that leaves your target profit after the costs entered. Use the separate MAO calculator to compare it with the 70% rule.

Should principal payments count as cost?

Principal affects cash requirements and payoff but is not the same as interest expense. Avoid counting principal both in costs and in the final loan payoff.

Can I share the result?

Yes. Calculate the scenario, then copy the generated share link. The inputs are stored in the URL, not sent to Rehabfolio.
