How to Use This Flip Calculator
Enter the purchase price, estimated rehab costs, holding costs, selling costs, and the after-repair value (ARV) to instantly see your expected profit, ROI, profit margin, and whether the deal passes the 70% rule. This calculator is used by flippers to quickly evaluate potential deals before committing.
Key Metrics Explained
- Total Investment — Purchase price + rehab + holding costs + selling costs. Everything you put in.
- ROI (Return on Investment) — Profit divided by total investment. Higher is better; most flippers target 15%+ ROI.
- Profit Margin — Profit divided by ARV. Shows how much of the sale price is profit.
- 70% Rule — Your max purchase price should be 70% of ARV minus rehab costs. This is the most common quick-screening formula used by professional flippers.
Frequently Asked Questions
What is the 70% rule in house flipping?
The 70% rule states you should pay no more than 70% of the ARV minus repair costs. For example, if ARV is $300,000 and rehab is $40,000, your max offer should be $300,000 × 0.70 − $40,000 = $170,000. This builds in a safety margin for profit and unexpected costs.
What are typical holding costs for a flip?
Holding costs include loan payments, property taxes, insurance, utilities, and HOA during the rehab period. A typical 4-6 month flip might cost $1,500-$3,000/month in holding costs depending on the property and financing terms.
What is a good ROI for a house flip?
Most experienced flippers target 15-25% ROI per deal. Anything above 20% is considered excellent. Below 10% is risky because unexpected costs can easily wipe out your margin.
How do I estimate ARV (After Repair Value)?
ARV is estimated by looking at comparable sales (comps) of recently sold, renovated homes in the same neighborhood with similar size and condition. Use our ARV Calculator for a detailed estimate, or work with a local real estate agent for a CMA.
