About House Flipping Profit Calculator
The House Flipping Profit Calculator is a comprehensive tool for real estate investors who buy, renovate, and sell properties for profit. Whether you are evaluating your first flip or analyzing your hundredth deal, this calculator accounts for every cost — purchase price, renovation budget, closing costs, agent commissions, holding costs, and financing — to give you an accurate picture of your potential net profit and return on investment.
What Is House Flipping?
House flipping is a real estate investment strategy where an investor purchases a property (usually below market value), renovates it to increase its value, and then sells it for a profit. The key to success is buying right, controlling renovation costs, and selling quickly to minimize holding costs.
Key Metrics Explained
After Repair Value (ARV)
The ARV is the estimated market value of the property after all renovations are complete. It is determined by analyzing comparable sales (comps) of recently sold, similar properties in the same area. Getting an accurate ARV is the single most important factor in evaluating a flip deal.
The 70% Rule
The 70% Rule is a widely-used guideline among house flippers to quickly evaluate whether a deal is worth pursuing:
For example, if a property has an ARV of $300,000 and needs $50,000 in repairs, the maximum you should offer is $300,000 × 0.70 − $50,000 = $160,000. The remaining 30% of ARV covers closing costs, commissions, holding costs, and your profit margin.
Return on Investment (ROI)
ROI measures the percentage return on the cash you invested. It is calculated as:
Since house flips vary in duration, Annualized ROI normalizes the return to a 12-month basis, allowing you to compare a 3-month flip with a 9-month flip on equal terms.
Cost Categories in a House Flip
| Cost Category | Typical Range | Notes |
|---|---|---|
| Purchase Price | Varies | Aim for below-market distressed properties |
| Repair / Renovation | $15,000 – $100,000+ | Always add a 10-20% contingency buffer |
| Buying Closing Costs | 1% – 3% | Title insurance, inspections, recording fees |
| Selling Closing Costs | 1% – 3% | Title fees, transfer taxes, escrow |
| Agent Commission | 5% – 6% | Typically split between buyer and seller agents |
| Monthly Holding Costs | $500 – $2,000+ | Taxes, insurance, utilities, HOA, lawn care |
| Financing (Hard Money) | 8% – 15% APR + 1-3 pts | Interest-only payments, short-term |

Tips for Successful House Flipping
- Buy right — The profit is made at purchase, not at sale. Never overpay.
- Get accurate repair estimates — Walk the property with a contractor before making an offer. Add 15-20% contingency for surprises.
- Know your market — Study comparable sales, days on market, and neighborhood trends.
- Minimize holding time — Every month you hold costs money. Plan renovations efficiently and list quickly.
- Build a reliable team — Good contractors, agents, and lenders are essential partners.
- Have reserves — Keep 3-6 months of holding costs as reserves for unexpected delays.
Frequently Asked Questions
What is the 70% Rule in house flipping?
The 70% Rule states that an investor should pay no more than 70% of a property's After Repair Value (ARV) minus repair costs. It is a quick screening formula to ensure adequate profit margin. For example, if ARV is $300,000 and repairs cost $50,000, the maximum offer should be $300,000 × 0.70 − $50,000 = $160,000.
What is a good ROI for a house flip?
Most experienced flippers target a minimum 10-20% ROI on their total cash invested. Deals with over 20% ROI are considered excellent. However, the best metric is annualized ROI since a 15% return in 3 months is far better than 15% over 12 months.
What costs are involved in flipping a house?
The main costs include: purchase price, renovation/repair costs, buying closing costs (1-3% of purchase price), selling closing costs (1-3% of sale price), real estate agent commissions (5-6% of sale price), monthly holding costs (property taxes, insurance, utilities, HOA), and financing costs (interest payments, origination fees/points).
How long does a typical house flip take?
Most flips take 3-9 months from purchase to sale. Simple cosmetic renovations may take 2-3 months, while major gut renovations can take 6-12 months. The holding period significantly affects total costs and ROI.
Should I use financing or all cash for a house flip?
Both have trade-offs. All cash eliminates interest costs and provides faster closings, but ties up more capital. Financing (hard money loans) lets you leverage your cash across multiple deals but adds interest and loan fees. Use the calculator to compare both scenarios.
What is hard money lending?
Hard money loans are short-term, asset-based loans commonly used by house flippers. They typically offer 65-80% loan-to-value, charge 8-15% annual interest, require 1-3 origination points, and feature interest-only monthly payments with a balloon payment at sale.
