About this Rehab Budget Calculator
A rehab budget should separate direct repair scope from contingency and soft costs. This calculator keeps those buckets visible so a deal does not depend on a single rounded repair number.
Who this calculator is for
- Real estate investors screening rental, flip, or refinance scenarios with transparent assumptions.
- Operators comparing user-entered costs, reserves, loan amounts, rents, fees, and rates before deeper diligence.
- Analysts who need deterministic first-pass deal math without hidden market data or lender assumptions.
When to use it
- Screen an acquisition, rehab, flip, BRRRR, or debt scenario before making an offer.
- Stress-test how vacancy, repair contingency, sale fees, financing, reserves, and refinance terms change the outcome.
- Document a simple formula-based estimate before ordering inspections, lender quotes, tax review, or legal review.
How to use this calculator
- Enter the property, rent, cost, fee, reserve, rate, or loan assumptions for the scenario.
- Review the primary output first, then compare supporting outputs to see which inputs drive the estimate.
- Run conservative cases with higher costs, higher vacancy, higher rates, lower rent, lower ARV, or lower refinance proceeds before relying on the result.
Key assumptions
- All costs, rents, ARV, loans, reserves, fees, and rates are user-entered assumptions.
- Calculations are deterministic and do not fetch market rents, tax rules, insurance quotes, lender terms, or property records.
- Results are estimates only and are not financial, tax, legal, lending, appraisal, inspection, or investment advice.

Things to Keep in Mind
This calculator is a planning model only. It does not predict appreciation, market liquidity, lender approval, tax treatment, insurance availability, permit risk, legal obligations, construction defects, tenant behavior, or final sale price.
Tips & Best Practices
- Keep a conservative case with lower income, higher costs, and longer timelines beside your expected case.
- Separate operating expenses from debt service so NOI, cash flow, and loan metrics remain clear.
- Confirm property condition, title, taxes, insurance, zoning, permits, lending terms, and exit assumptions with qualified professionals.
