Fix and Flip Calculator
Estimate profit and ROI on fix-and-flip projects.
What Is Fix and Flip?
Fix and flip is a real estate investment strategy centered on buying undervalued or distressed properties, renovating them to increase market value, and selling for a profit. Unlike buy-and-hold investing, where returns accumulate over years through rent and appreciation, flipping generates a single lump-sum profit at the end of a relatively short project timeline.
The appeal of house flipping is straightforward: with the right deal, you can earn a substantial return in a matter of months rather than years. A successful flip might generate $50,000–$100,000 in profit on a single project, representing a return on invested capital that far exceeds what most traditional investments offer over the same period.
However, flipping carries concentrated risk. Unlike a rental property that generates income over decades, a flip is a single transaction where timing, cost control, and accurate pricing all converge. A miscalculation in any one of these areas can turn a projected profit into a loss. The fix and flip calculator helps you model every cost component so you can evaluate whether a specific deal meets your profit threshold before committing capital.
How to Use This Calculator
Purchase Price and Renovation
Enter the price you will pay for the property and the estimated renovation budget. Be specific about renovation costs: get contractor bids, research material costs, and add a contingency of at least 10%–15%. Underestimating renovation costs is the single most common reason flips fail.
Holding Costs
Enter the monthly holding costs while the property is being renovated and listed for sale. These include mortgage or hard money loan payments, property taxes, insurance, utilities, HOA fees, and any other recurring costs. Holding costs accumulate every month the project takes, so accurate time estimates are critical.
Selling Costs
Enter the estimated selling costs, including real estate agent commissions (typically 5%–6% of sale price), staging, buyer concessions, and closing costs. These are deducted from your sale price to determine your net proceeds.
After-Repair Value (ARV)
Enter the estimated sale price after renovations are complete. This should be based on comparable sales of similar renovated properties in the immediate area. Overestimating ARV is one of the most dangerous mistakes in flipping — always be conservative.
Cost Breakdown
Acquisition Costs
Beyond the purchase price, budget for closing costs (typically 2%–5% of purchase price for buyers), title insurance, inspection fees, and any legal fees. If using a hard money loan, include origination points (1%–3% of the loan amount) and any application or processing fees.
Renovation Costs
Get detailed bids from at least two contractors before committing to a deal. Categorize renovations as "must-do" (structural, safety, code compliance) and "nice-to-have" (cosmetic upgrades). Must-do work is non-negotiable; nice-to-have work should only be included if it demonstrably increases the ARV by more than its cost.
Holding Costs
Holding costs are the ongoing expenses you pay while the property is in your possession: mortgage interest or hard money loan payments, property taxes, insurance, utilities, lawn care, security, and HOA fees. These costs can add up to $2,000–$5,000 per month or more, making project duration a critical variable in your profit calculation.
Selling Costs
Budget for real estate agent commissions (5%–6% of sale price is standard), transfer taxes, title insurance for the buyer, any seller concessions or home warranty contributions, and staging costs. Selling costs typically consume 6%–8% of the gross sale price.
Profit Formula
Net Profit = Sale Price − Purchase Price − Renovation Costs − Holding Costs − Selling Costs − Acquisition Costs
ROI (%) = Net Profit / Total Cash Invested × 100
Where "Total Cash Invested" includes the down payment (or full purchase price if all cash), closing costs, renovation costs, and holding costs paid during the project. The ROI tells you what percentage return you earned on the money you actually put into the deal.
Worked Examples
Example 1: Profitable Flip
Purchase price: $180,000. Renovation: $45,000. Holding costs (4 months): $8,000. Selling costs: $24,000 (6% of $400,000). Acquisition costs: $5,000. Total cost: $262,000. Sale price (ARV): $300,000. Net profit: $300,000 − $262,000 = $38,000. Total cash invested: $230,000 (purchase + renovation + holding + acquisition). ROI: $38,000 / $230,000 = 16.5%. This is a solid flip with a reasonable return for a 4-month project.
Example 2: Marginal Flip
Purchase price: $250,000. Renovation: $60,000. Holding costs (6 months): $18,000. Selling costs: $28,500 (6% of $475,000). Acquisition costs: $7,000. Total cost: $363,500. Sale price: $475,000. Net profit: $111,500. However, total cash invested was $335,000. ROI: $111,500 / $335,000 = 33.3%. While the ROI looks high, the absolute dollar risk is significant. If the ARV falls short by even 10%, profit shrinks dramatically.
Example 3: Losing Flip
Purchase price: $200,000. Renovation estimate: $50,000. Actual renovation: $70,000 (overrun). Holding costs (7 months): $21,000 (extended due to delays). Selling costs: $25,500 (6% of $425,000). Acquisition costs: $6,000. Total cost: $322,500. Sale price: $425,000. Net profit: $102,500. This example illustrates how cost overruns and delays can still produce a profit, but if the ARV had come in at $350,000 instead of $425,000, the flip would have lost money.
Tips for Flippers
The 70% Rule Is Your Friend
Pay no more than 70% of the after-repair value minus renovation costs. This built-in margin accounts for holding costs, selling costs, and unexpected overruns. If the numbers do not work at 70%, walk away. There are always more deals.
Get Contractor Bids Before Buying
Never estimate renovation costs from a walkthrough alone. Get written bids from licensed contractors before committing to a purchase. The difference between your guess and the actual bid can be the difference between profit and loss.
Add a 15% Contingency
Unexpected issues — hidden water damage, outdated wiring, structural problems — are the norm, not the exception, in renovation projects. Add at least 15% to your renovation budget as a contingency. If you do not need it, you keep more profit. If you do need it, you avoid going over budget.
Speed Is Profit
Every month of holding costs reduces your profit by $2,000–$5,000 or more. Plan your renovation timeline carefully, line up contractors before closing, and have materials pre-ordered. The faster you complete the project, the more money you keep.
Do Not Fall in Love with a Property
Emotional attachment leads to overpaying, over-renovating, or holding too long waiting for a higher offer. Treat every flip as a numbers game. If the deal does not meet your profit threshold at the purchase stage, it will not magically become profitable later.
Frequently Asked Questions
What is fix and flip?
Fix and flip is a real estate investment strategy where you purchase a distressed or undervalued property, renovate it to increase its value, and sell it for a profit. The entire cycle — purchase, renovation, and sale — typically takes 3 to 12 months. Successful flippers earn a profit by buying below market value, controlling renovation costs, and selling at or above market value.
How much profit do house flippers make?
Profit varies enormously depending on the market, the deal, and the flipper's skill. A common rule of thumb is the 70% rule: pay no more than 70% of the after-repair value (ARV) minus renovation costs. On a $300,000 ARV property, that means a maximum purchase price of $300,000 × 0.70 = $210,000, minus renovations. Actual gross profits typically range from $30,000 to $80,000 per flip in most markets, but this varies widely.
What is the 70% rule in house flipping?
The 70% rule states that you should pay no more than 70% of the after-repair value (ARV) of a property, minus the cost of renovations. For example, if a renovated property would be worth $300,000 and renovations cost $40,000, your maximum offer price should be $300,000 × 0.70 − $40,000 = $170,000. This rule provides a built-in margin for holding costs, selling costs, and unexpected expenses.
What costs should I include in a fix and flip analysis?
Include every cost: purchase price, closing costs (both buy and sell), renovation costs, holding costs (mortgage interest, insurance, property taxes, utilities during the renovation period), contractor overhead, permits, and selling costs (agent commissions, staging, closing costs). Many failed flips are caused by underestimating one or more of these categories.
How long does a typical flip take?
Most fix and flip projects take 3 to 6 months from purchase to sale, with 2 to 4 months of active renovation and 1 to 2 months for listing, marketing, and closing. Larger renovations or properties in slow markets can take 6 to 12 months. Every month of holding costs reduces your profit, so speed is critical.
Do I need a contractor or can I do the work myself?
You can do some or all of the work yourself if you have the skills, but be realistic about your abilities and the time commitment. Electrical, plumbing, and structural work typically require licensed contractors and permits. Cosmetic work (painting, landscaping, flooring) is often DIY-friendly. The biggest risk of self-performing is that delays increase your holding costs and eat into profit.
What is after-repair value (ARV)?
After-repair value (ARV) is the estimated market value of a property after all renovations are complete. It is determined by analyzing comparable sales of similar renovated properties in the immediate area. ARV is the most critical number in a flip analysis because it determines your revenue ceiling. Overestimating ARV is one of the most dangerous mistakes in house flipping.
Should I use hard money or a conventional loan for flipping?
Most house flippers use hard money loans or private lending because conventional mortgages are too slow and require the property to be habitable. Hard money loans close quickly (days, not weeks), are based on the property value rather than your income, and have short terms (6–18 months) suited to the flip timeline. The trade-off is higher interest rates (8%–15%) and origination points.
What are the biggest risks in house flipping?
The biggest risks are: underestimating renovation costs, overestimating the after-repair value, unexpected structural issues (foundation, roof, plumbing, electrical), market downturns during the renovation period, contractor delays, and holding cost overruns. Mitigating these risks requires thorough due diligence, conservative underwriting, and maintaining a cash reserve of at least 10%–15% of total project costs.
