How to Calculate Real Flip Profit in 2026 (Not Just the Spread)

Most new flippers look at a deal and think: “I buy for $200K, sell for $300K—easy $100K profit.” In 2026, that math gets you a loss. Hard money rates sit at 12% (sometimes higher for 60-day flips), conventional money is 7.5%, and holding costs eat spreads alive. You need to calculate real profit, not just the gross spread.

Let’s walk through a specific 2026 flip scenario with real numbers. This is the difference between a winner and a deal that bleeds cash.

The Gross Spread Lie

Say you find a 3-bed, 2-bath in Phoenix. Asking price: $220,000. ARV (after-repair value) based on comps: $315,000. That’s a $95,000 spread. Looks good, right? Most flippers stop there. But here’s where 2026 costs change everything.

Your real costs:

• Purchase price: $220,000
• Hard money loan (12% interest): $220,000 loan, 3 points ($6,600), 6-month term. Interest alone: $220,000 x 0.12 / 2 = $13,200. Total hard money cost: $19,800.
• Rehab: $40,000 (mid-range kitchen, baths, flooring, paint, new roof).
• Holding costs: 6 months property taxes ($2,400), insurance ($1,800), utilities ($1,200), HOA ($600). Total: $6,000.
• Selling costs: 6% realtor commission ($18,900), closing costs ($5,000), staging ($2,000). Total: $25,900.
• Carrying cost on your capital: You put down 20% ($44,000) plus rehab ($40,000) = $84,000 cash. At 5% opportunity cost for 6 months: $2,100.

Total costs: $220,000 (purchase) + $19,800 (hard money) + $40,000 (rehab) + $6,000 (holding) + $25,900 (selling) + $2,100 (opportunity) = $313,800.

Profit: $315,000 - $313,800 = $1,200. On a deal that looked like $95K spread. That’s a borderline fail.

Use a Fix and Flip Calculator before you sign anything. Plug in your local carrying costs. The spread is not profit.

The 70% Rule in 2026

The old rule: buy at 70% of ARV minus rehab. In 2026, with 12% hard money, that rule needs adjusting. A safer target is 65% of ARV minus rehab. Why? Because holding costs and interest are higher.

Example: ARV $315,000. Rehab $40,000.

• 70% rule: $315,000 x 0.70 = $220,500 minus $40,000 = $180,500 max purchase price.
• 65% rule: $315,000 x 0.65 = $204,750 minus $40,000 = $164,750 max purchase price.

Which is right? Run your actual numbers. At $180,500 purchase, your profit is negative with 12% hard money. At $164,750, you leave room.

Use a 70% Rule Calculator with your specific loan terms. The rule is a starting point, not a guarantee.

Hard Money Math Gets Brutal

Hard money in 2026 averages 12% with 2-4 points. That’s $12,000-$16,000 interest per $100K borrowed per year. On a $220K loan for 6 months, you’re paying $13,200+ in interest alone. Points add $4,400-$8,800. Total hard money cost: $17,600-$22,000.

That’s a chunk of your spread. If your spread is $95K, hard money eats 18-23% of it. Then you still have realtor fees, taxes, and rehab.

Use a Hard Money Calculator to see the exact cost for your loan amount and term. Know your breakeven sale price before you buy.

Rehab Costs Are Up

In 2026, materials and labor are 8-12% higher than 2023. A basic kitchen remodel runs $25K-$35K. Bathroom: $10K-$15K. New roof: $8K-$12K. Permits and dumpsters add $2K-$4K.

Don’t guess. Get three contractor quotes. Add a 15% contingency (materials go up, you find rot, etc). On a $40K rehab, that’s $6K buffer.

Use a Rehab Cost Estimator to itemize your budget by room. The difference between a $35K and $45K rehab is real profit.

Real Profit Calculation Step-by-Step

Here’s the formula for 2026:

1. ARV – Use comps within 3 months and 0.5 miles. Adjust for condition.
2. Purchase price – Your offer price.
3. Loan costs – Points + interest for expected hold time.
4. Rehab – Contractor bids + 15% contingency.
5. Holding – Taxes, insurance, utilities, HOA per month x months.
6. Selling – Realtor commission (5-6%), closing costs (2-3%), staging, photos.
7. Opportunity cost – Your cash could earn 5-7% elsewhere.

Real profit = ARV – (Purchase + Loan costs + Rehab + Holding + Selling + Opportunity)

Example with $315K ARV, $180K purchase, $40K rehab, 6-month hold:

• Loan costs: $180K x 0.12 / 2 = $10,800 interest + 3 points ($5,400) = $16,200
• Holding: $2,400 tax + $1,800 insurance + $1,200 utilities + $600 HOA = $6,000
• Selling: $18,900 commission + $5,000 closing + $2,000 staging = $25,900
• Opportunity: $80K cash (20% down + rehab) x 5% / 2 = $2,000

Total costs: $180K + $16,
