How the all-in renovation budget is built
This calculator turns acquisition, work, contingency, soft costs and financing costs into one project budget, then compares that budget with entered equity and an assumed completed value.
Contingency equals the renovation work budget times the entered contingency percentage. Total project cost equals acquisition cost plus work budget, contingency, soft costs and financing costs. Funding need is the positive difference between total project cost and entered project equity. The tool then divides that funding need by assumed completed value to show an illustrative loan-to-completed-value ratio.
Work budget × contingency %Creates a specific buffer tied to the construction budget.
Acquisition + work + contingency + soft costs + finance costsCombines the major entered uses of funds.
max(0, total project − equity) ÷ completed value × 100An illustrative leverage metric, not a product limit.
Use a work budget grounded in a real scope rather than a rough percentage of purchase price.
Enter a contingency that reflects project uncertainty and lender/program requirements separately.
Include permits, design, inspections or other soft costs where relevant.
Stress-test a higher work budget and lower completed value before relying on the funding ratio.
Best used for
- Building an acquisition-plus-renovation budget
- Sizing a rough funding gap after equity contribution
- Seeing how contingency or completed value changes leverage
What this tool does not answer
- The tool does not validate contractor bids or completed value.
- It does not model draw schedules, interest reserves or construction inspection timing.
- The leverage ratio is illustrative and is not a lender limit or approval.
How to read a sample result
Illustrative example: $200,000 acquisition + $50,000 work + 10% contingency ($5,000) + $5,000 soft costs + $10,000 financing costs = $270,000 total project cost. With $70,000 of equity, modeled funding need is $200,000; against a $300,000 assumed completed value, that is about 66.67%.
The methodology below explains how this calculator treats the inputs and assumptions. Replace the sample values with your own planning figures. Results are estimates, not quotes, approvals, disclosures or recommendations.
Inputs and units
Acquisition cost, work budget, contingency percentage, soft costs, financing costs, equity and completed-value assumption. All currency entries are U.S. dollars. Percentage fields take a number such as 6 for six percent, not 0.06. Repayment terms marked in months use whole months; horizons marked in years use whole years.
Calculation workspace
Enter your own figures in the calculator above. The starting values are examples only. No personal identifiers are needed to run a scenario.
How to interpret the result
Read every result together with the assumptions you entered. Changing an input changes the scenario, not product availability. Displayed amounts are rounded for readability.
Assumptions and limitations
Funding gap and illustrative leverage are not loan approval. Renovation spending does not guarantee a matching increase in property value.
Review more than one scenario
Run a base case and then change one uncertain input at a time. Compare a shorter holding period, a higher cost or a different repayment term where those inputs are supported. Record which costs have not been entered. A precise-looking number can still rest on uncertain assumptions.
Invalid inputs and error recovery
If an input is missing or outside the calculator’s supported range, the page will ask you to correct it. Use negative values only in fields that explicitly allow them. A calculation error is not a credit decision.
Model documentation
The calculator methodology explains the inputs, assumptions and supported models. Use the result for planning and compare it with the provider’s written terms and applicable disclosures before making a decision.
