What is BRRRR Calculator?
The BRRRR Calculator helps investors analyze the returns of the BRRRR real estate strategy.
When to Use This Calculator
- Evaluating whether a distressed property qualifies for the BRRRR cycle — check if total cost stays under 70-75% of ARV.
- Deciding refinance timing — model different seasoning periods and their impact on cash flow.
- Stress-testing the 75% ARV cash-out assumption against actual lender terms in your market.
- Planning capital recycling across multiple properties — see how quickly you can scale a portfolio.
- Comparing BRRRR vs fix-and-flip returns on the same property to choose the better strategy.
- Budgeting for holding costs during the seasoning period when the property generates rental income but you can't yet refinance.
Steps:
- Enter purchase price and down payment.
- Input rehab costs and ARV.
- View equity and ROI.
Formula
Total Investment = Down Payment + Closing Costs + Rehab Costs
Equity = ARV − (Purchase Price − Down Payment)
Cash Out = (ARV × 0.75) − (Purchase Price − Down Payment)
Cash-on-Cash Return = (Cash Out / Total Investment) × 100
ROI = ((Equity − Total Investment) / Total Investment) × 100
Where: ARV = After Repair Value
Use Cases
- BRRRR analysis
- Portfolio building
- Investment planning
Key Benefits
- Recycle the same capital across multiple properties through cash-out refinancing
- Build long-term wealth through cash flow and appreciation simultaneously
- Model BRRRR scenarios with realistic ARV, rehab, and refinance assumptions
- Compare BRRRR returns against fix-and-flip and buy-and-hold strategies
Pro Tips
- Target 70% ARV all-in cost (purchase + rehab + closing) for a conservative deal that works even if appraisal comes in low
- Get pre-approved for the refinance before purchasing — know your lender's LTV requirements and rates
- Budget 15-20% rehab contingency and a 3-month buffer for seasoning period carrying costs
- Verify rental demand in the area before buying — the 'Rent' step is critical for refinancing approval
Common Mistakes to Avoid
- Overestimating ARV — always verify with comparable sales within 0.5 miles and 3 months, not aspirational values
- Underestimating rehab costs — add 15-20% contingency to contractor estimates for surprises
- Ignoring the seasoning period — you can't refinance immediately; plan for 6-12 months of holding costs
- Not accounting for refinance closing costs — second-round closing costs (1-3% of new loan) reduce your cash-out
Key Terms Explained
- ARV (After Repair Value): The estimated property value after all rehabilitation is complete — the most critical input for BRRRR analysis.
- 70% Rule: Maximum all-in cost should be 70% of ARV to ensure sufficient equity for refinancing.
- Seasoning Period: The minimum ownership period (6-12 months) required before a lender allows cash-out refinancing.
- Cash-Out Refinance: A new loan on the appraised value that returns your invested capital for reuse.
- Capital Recycling: The process of recovering invested capital through refinancing to deploy into new deals.
- DSCR Loan: Debt Service Coverage Ratio loan that qualifies based on rental income rather than personal income.

Example
A $200K purchase with $40K down, $30K rehab, and $350K ARV creates significant equity.
Interpreting Your Results
The BRRRR calculator shows you three key outputs: equity created, cash available from refinancing, and return on investment. Equity created is the difference between ARV and your total cost — this is your paper wealth. Cash out is what you actually receive from the refinance. ROI measures how efficiently your capital is working.
The 70-75% ARV target is the deal-maker or deal-breaker. If your total cost (purchase + rehab + closing) exceeds 75% of ARV, the refinance may not return all your capital, leaving you 'stuck' with money trapped in the deal. Conservative investors target 70% to build in a safety margin.
Appraisal risk is the single biggest BRRRR failure mode. If the appraiser values the property lower than your ARV estimate, you receive less cash out. Always verify ARV with multiple comparable sales and be conservative in your estimates. The calculator shows sensitivity to ARV changes — use it to understand your downside scenario.
