What this tool does
Calculate arv from your own entered figures. User-entered property figures only. Estimates exclude costs not entered and are not investment advice. The 70% rule is an investor convention for leaving room for holding, financing and selling costs plus profit — it is not an appraisal, a law, or a guarantee a deal works at that price.
How to use the ARV Calculator
- Enter or select after repair value (arv).
- Enter or select estimated repair costs.
- Enter or select arv percentage for the rule (%).
- Read the calculated result; change any measurement to compare alternatives.

Frequently asked questions
A screening convention: pay no more than 70% of the after repair value minus repair costs. On a $300,000 ARV with $40,000 of repairs, the maximum offer is $210,000 − $40,000 = $170,000.
From comparable sales — recently sold, renovated homes similar in size, condition and location to what the property will be after repairs. ARV is an estimate, and an optimistic ARV is the most common way flip deals go wrong.
The missing 30% is meant to absorb holding costs, financing, selling commissions and closing costs, and leave profit. In high-cost or slow markets investors use a lower percentage; competitive markets push some to bid above the rule and accept thinner margins.
The repairs alone exceed the rule's budget at that ARV — the deal cannot work under the 70% rule at any positive price, so the ARV, the repair scope, or the strategy needs to change.
Not explicitly — they are what the 30% cushion is for. For a precise check, run the full purchase, rehab, holding, financing and selling stack in the house flip calculator instead.
