Free Fix and Flip DCF Analyzer (2026)
Evaluate house flipping deals with time-weighted cash flow analysis
Why Fix and Flip Matters
Assess fix-and-flip projects using DCF methodology that accounts for renovation timelines, holding costs, and time value of money. Model acquisition costs, construction budgets, monthly carrying expenses, and after-repair value (ARV) to calculate NPV and determine if a flip opportunity meets your return requirements. Ideal for short-term real estate investors who need to factor time and capital costs into profitability analysis.

Tips & Best Practices
Use higher discount rates (15-25%) for flips to reflect short-term capital opportunity cost and risk
Model monthly holding costs separately: mortgage interest, taxes, insurance, utilities (typically $800-2,000/month)
Include contingency buffers: add 15-20% to renovation budget and 1-2 months to timeline estimates
Account for selling costs in exit value: 6% commission, 1-2% closing costs, 1% concessions = ~8-9% total
Use actual calendar months for cash flows—a 6-month flip has very different NPV than a 12-month flip at 20% discount rate
Compare DCF NPV to simple profit margin—if they diverge significantly, your timeline assumptions may be unrealistic
Frequently Asked Questions
DCF accounts for time value of money, which matters enormously in flips. A $40,000 profit on a 4-month flip is far superior to the same profit on a 10-month flip because your capital is tied up longer. DCF reveals whether you're actually beating alternative investments like stock market returns (annualized) after accounting for time and risk.
Use 15-25% discount rates for most flips to reflect the high-risk, short-term nature of the investment. Lower end (15-18%) for experienced flippers in stable markets with predictable renovation scopes. Higher end (20-25%) for first-time flippers, challenging properties, or volatile markets where comps and timelines are uncertain.
Month 0: negative cash flow = purchase price + closing costs. Months 1-N: negative cash flows = renovation costs + holding costs (mortgage, taxes, insurance, utilities). Final month: positive cash flow = ARV minus selling costs minus any remaining renovation/holding costs. Discount each month's cash flow back to present value using your monthly discount rate.
Yes, if you're doing work yourself that you'd otherwise pay contractors to do. Value your time at what you'd pay a professional for the same work—this gives you true economic profit. If NPV is only positive when you exclude your labor value, you're essentially working a low-wage job rather than making a real investment return.
Timeline dramatically impacts NPV—every extra month erodes returns through holding costs and time value of money. At a 20% annual discount rate, a $50,000 profit on a 4-month flip has ~15% higher NPV than the same profit on an 8-month flip. Model realistic timelines including permit delays, contractor scheduling, and seasonal market slowdowns for accurate analysis.
Target NPV of at least 15-20% of your total invested capital (purchase + renovation + holding costs) to justify the risk and effort. For a $200,000 all-in project, aim for minimum $30,000-40,000 NPV. Higher NPV thresholds (25-30%) make sense for newer flippers, difficult properties, or markets with high volatility where actual results often fall short of projections.
