Formula Used
Hard Costs = Labor Cost + Material Cost
Soft Costs = Permit Cost + Design Fee + Miscellaneous Cost + Closing Costs
Contingency Cost = (Hard Costs + Soft Costs) × Contingency %
Loan Base = (Purchase Price + Hard Costs + Soft Costs + Contingency Cost) × Financed Share %
Interest Cost = Loan Base × Annual Interest Rate × Holding Months ÷ 12
Loan Points Cost = Loan Base × Loan Points %
Financing Cost = Interest Cost + Loan Points Cost
Total Rehab Cost = Hard Costs + Soft Costs + Contingency Cost + Financing Cost
All In Cost = Purchase Price + Total Rehab Cost
Selling Cost = After Repair Value × Selling Cost %
Projected Profit = After Repair Value − Selling Cost − All In Cost
ROI % = Projected Profit ÷ All In Cost × 100
Target Profit Amount = After Repair Value × Target Profit %
Budget Gap = Target Profit Amount − Projected Profit
Break Even Sale Price = All In Cost ÷ (1 − Selling Cost %)
Maximum Allowable Offer = After Repair Value − Selling Cost − Total Rehab Cost − Target Profit Amount

Frequently Asked Questions
1. What does this rehab cost calculator estimate?
It estimates total renovation spending, financing costs, selling costs, projected profit, target profit gap, break even sale price, and maximum allowable offer.
2. Why should I include contingency costs?
Contingency covers hidden damage, price changes, delays, and scope creep. It helps keep your deal analysis realistic and protects expected returns.
3. What is after repair value?
After repair value is the estimated market value after renovation work is finished. It is a key number for resale planning and profit analysis.
4. How are financing costs calculated here?
Financing costs combine interest expense and loan points. The calculator uses your financed share, annual interest rate, and holding period to estimate them.
5. What does maximum allowable offer mean?
It shows the highest purchase price you can pay while still covering rehab costs, selling costs, and your target profit goal.
6. Can I use this for rental rehabs?
Yes, but this version is resale focused. For rentals, also review rent, vacancy, refinance assumptions, taxes, insurance, and cash flow.
7. What does the budget gap show?
Budget gap compares your target profit with projected profit. A positive gap means the deal is under target and needs improvement.
8. Why export results to CSV or PDF?
Exports help you document assumptions, share summaries, compare multiple deals, and keep a clean record for lenders or investment partners.
