“House flipping looks profitable on TV. This house flipping ROI calculator shows you the real numbers for your specific deal.”

Use this free house flipping ROI calculator to find your real net profit and return on invested capital after purchase price, renovation costs, holding costs, selling agent commissions, closing costs, and capital gains tax — before you make an offer.

What This House Flipping ROI Calculator Shows You

• Net profit after all purchase renovation and selling costs
• ROI percentage on your total invested capital
• Annualized return based on your project timeline
• Minimum ARV needed to hit your target profit
• Whether your deal works at different renovation budget scenarios

Is This Flip Actually Worth Doing?

The 70% rule is a useful starting point for house flipping — but it does not tell you your actual ROI or profit after every cost is accounted for. Purchase price, renovation budget, holding costs during the project, selling agent commissions, closing costs, and capital gains tax all determine whether a flip generates meaningful profit or barely breaks even.

This house flipping ROI calculator runs the full math so you know before you make an offer whether the deal actually works at your numbers.

How to Use This House Flipping ROI Calculator

Enter your purchase price, estimated renovation budget, renovation contingency percentage, project timeline in months, hard money loan rate if applicable, monthly holding costs, expected ARV, selling agent commission percentage, and closing costs.

Add your capital gains tax rate to see post-tax net profit and ROI. The house flipping ROI calculator shows your minimum viable ARV and whether your deal meets your target return.

The Costs That Kill Flip Profits in 2026

This house flipping ROI calculator accounts for all three cost categories that consistently destroy flip margins:

Holding costs are chronically underestimated — property taxes, insurance, utilities, and loan interest during a 4-6 month renovation add up fast. On a $200,000 property with a hard money loan at 12% annual interest you are paying $2,000/month in interest alone — $12,000 over a 6-month project before a single nail is hammered.

Renovation overruns are nearly universal — experienced flippers build a 15-20% contingency into every renovation budget without exception. If your house flipping ROI calculator numbers only work at the initial renovation estimate with no buffer the deal is too thin to take. One unexpected foundation issue or roof replacement can eliminate your entire margin.

Selling costs are fixed and large — realtor commissions typically 5-6%, buyer closing cost contributions, staging, and transaction costs run 8-10% of the sale price. On a $300,000 ARV that is $24,000-30,000 off the top before you see a dollar of profit. Many first-time flippers forget to include this in their deal analysis.

What a Realistic House Flip Looks Like in 2026

Here is what this house flipping ROI calculator shows for a typical mid-market flip:

Purchase price:              $180,000
Renovation budget:            $45,000
Contingency (15%):             $6,750
Hard money interest (6 mo):   $12,960
Monthly holding costs:         $3,600
Total costs in:              $248,310

ARV:                         $310,000
Selling costs (8%):          -$24,800
Net proceeds:                $285,200

Net profit:                   $36,890
ROI on invested capital:        14.8%
Annualized ROI:                 29.6%

That 14.8% ROI on a 6-month project looks reasonable — but notice how quickly it disappears if renovation runs 20% over budget ($9,000 more) or the project takes 9 months instead of 6 ($6,480 more in holding costs). Use this house flipping ROI calculator to test these scenarios before you buy.

The 70% Rule — What It Gets Right and Wrong

The 70% rule says you should pay no more than 70% of ARV minus renovation costs for a flip property. It is a useful quick filter but this house flipping ROI calculator gives you a more accurate picture because:

It does not account for holding costs — a 6-month project with hard money financing can add $15,000-25,000 in costs the 70% rule ignores entirely.

It does not account for selling costs — 8-10% in selling costs is not built into the standard 70% rule calculation.

It does not show ROI — knowing your net profit is useful but knowing your annualized ROI lets you compare flipping against other uses of the same capital.

Use the 70% rule as a first filter then run every deal through this house flipping ROI calculator before making an offer.

How to Improve Your Flip ROI

Use this house flipping ROI calculator to test each of these scenarios:

Reduce your purchase price — every $10,000 less you pay goes directly to net profit. Negotiating price is the highest-leverage action in any flip deal.

Shorten your timeline — every month saved on a hard money loan saves $2,000-3,000 in interest. Faster renovation and faster sale directly improves annualized ROI.

Increase ARV through strategic upgrades — kitchen and bathroom renovations typically return $1.50-2.00 for every $1.00 spent in most US markets. Focus renovation budget where it increases ARV most efficiently.

Reduce selling costs — consider selling without a buyer’s agent or negotiating commission rates. Even 1% reduction on a $300,000 sale saves $3,000 net profit.
