Calculation Method
House Flipping Profit Formula
The calculator subtracts all acquisition, renovation, financing, holding, selling, and additional expenses from the expected property sale price.
Net Profit Formula
Net Profit = After Repair Value − Total Project Cost
Total project cost includes the purchase price, purchase closing costs, renovation budget, contingency reserve, holding expenses, loan interest, lender points, loan fees, selling costs, and other project expenses.
Return on Investment Formula
ROI = Net Profit ÷ Cash Investment Required × 100
The cash investment calculation subtracts the loan amount from the costs financed at acquisition. It then includes expenses that normally require additional cash during the project.
Budget Planning
Common House Flipping Costs to Consider
Review these expense categories before deciding whether a property has enough room for a safe and realistic profit.
| Cost Category | Examples | Why It Matters |
|---|---|---|
| Purchase Costs | Purchase price, inspection, title fees and legal fees | These costs determine your initial property basis. |
| Renovation Costs | Labor, materials, permits, demolition and contractor fees | Underestimating repairs can eliminate the expected profit. |
| Holding Costs | Insurance, taxes, utilities, maintenance and security | Longer projects usually create higher ownership expenses. |
| Financing Costs | Interest, lender points, appraisal and origination fees | High-cost short-term financing can significantly reduce ROI. |
| Selling Costs | Agent commission, closing fees, staging and buyer concessions | These costs reduce the amount received from the final sale. |
| Contingency Reserve | Structural damage, delays and unexpected repairs | A reserve protects the project from unforeseen expenses. |
Frequently Asked Questions
House Flipping Calculator FAQs
Find answers to common questions about calculating house flipping costs, potential profit, ROI, and purchase offers.
A house flipping calculator estimates the financial outcome of buying,
renovating, holding, and reselling a property. It calculates total costs,
projected net profit, ROI, profit margin, break-even sale price, and a
possible maximum purchase price.
After repair value, commonly called ARV, is the estimated market value of
the property after all planned renovations are completed. Investors
generally estimate ARV by studying recently sold renovated properties
with similar locations, sizes, ages, and features.
The 70% rule suggests paying no more than 70% of the property's after
repair value minus estimated renovation costs. It is a quick screening
guideline, not a replacement for a detailed analysis of financing,
closing, holding, and selling expenses.
Many investors include a contingency reserve to cover unexpected work.
The appropriate percentage depends on the property's age, condition,
inspection findings, renovation complexity, contractor reliability, and
local material costs.
Holding expenses may include property taxes, insurance, utilities,
maintenance, lawn care, security, homeowner association fees, temporary
storage, cleaning, and other recurring ownership costs. Loan interest is
calculated separately in this tool.
ROI is calculated by dividing projected net profit by the estimated cash
investment required and multiplying the result by 100. The result helps
investors compare potential deals, but it should also be reviewed
alongside project duration and risk.
Yes. The calculator estimates simple loan interest using the loan amount,
annual interest rate, and holding period. It also includes lender points
and additional loan fees as separate financing expenses.
No. The maximum purchase price is an estimate based on your target profit
and entered costs. Before making an offer, verify the ARV, contractor
estimates, title condition, taxes, financing terms, permits, and local
selling expenses.
