Guessing at flip profits = overruns, lost money, failed flips. Accurate profit calculation = realistic expectations, successful flips, predictable returns. Here's how to calculate fix and flip profit correctly.

Fix and Flip Profit Formula

ARV (After Repair Value)

- Purchase Price

- Rehab Costs

- Holding Costs

- Selling Costs

= Net Profit

Calculate Flip Profit

The 5 Components of Flip Profit

1. ARV (After Repair Value)

What the property will sell for after renovations

How to Estimate ARV:

  • • Find 3-5 comparable sales (same beds/baths, similar condition)
  • • Properties sold within last 90 days, within 0.5 miles
  • • Adjust for differences (lot size, updates, garage)
  • • Use average, not highest sale price
  • • Add 5-10% pessimism buffer

Example: Comps at $250k, $255k, $260k → Use $255k ARV

2. Purchase Price

What you pay to acquire the property

Include These Costs:

  • • Purchase price
  • • Closing costs (2-3% of purchase)
  • • Inspection fees
  • • Appraisal costs

Example: $180k purchase + $5k closing = $185k total acquisition

3. Rehab Costs

Money spent renovating the property

Typical Rehab Items:

  • • Kitchen: $15k-30k
  • • Bathrooms: $8k-15k each
  • • Flooring: $3-8 per sq ft
  • • Paint: $2-4 per sq ft
  • • HVAC replacement: $5k-8k
  • • Roof: $8k-15k
  • • Permits: $500-2k
  • • Add 20% contingency buffer

Example: $35k estimated + 20% buffer = $42k budgeted

4. Holding Costs

Costs while you own the property

Monthly Holding Costs:

  • • Loan interest payments
  • • Property taxes
  • • Insurance
  • • Utilities
  • • HOA fees (if applicable)
  • • Multiply by months to hold (typically 6-8)

Example: $2,000/month × 6 months = $12k holding costs

5. Selling Costs

Costs to sell the finished property

Typical Selling Costs:

  • • Agent commission: 5-6% of ARV
  • • Closing costs: 1-2% of ARV
  • • Staging costs: $2k-5k
  • • Total: 7-9% of ARV typically

Example: $255k ARV × 8% = $20,400 selling costs

  • - Total Costs: -$259,400
  • Net Loss: -$4,400

Verdict: DON'T DO THIS DEAL! Needs lower purchase price or higher ARV.

The 70% Rule for Quick Analysis

Maximum Purchase Price Formula

Max Purchase = (ARV × 70%) - Rehab Costs

Example:

ARV: $255,000

Rehab: $42,000

Max Purchase: ($255k × 70%) - $42k = $136,500

The 70% rule ensures sufficient profit margin after all costs. Adjust to 65% in competitive markets or 75% if experienced.

Common Flip Calculator Mistakes

❌ Overly Optimistic ARV

Using highest comp instead of average = overestimating profit by $10k-30k. Use conservative ARV estimates.

❌ Underestimating Rehab Costs

Forgetting permits, dumpster, surprises during demo. ALWAYS add 20% rehab contingency buffer.

❌ Ignoring Holding Costs

6 months of loan interest, taxes, insurance = $10k-15k. Can turn profitable flip into break-even.

❌ Forgetting Selling Costs

Agent commission alone is 5-6% of ARV. On $250k flip = $12.5k-15k just in commission.
