Renovation ROI Calculator – Plan Multiple Projects & Financing
Pick a project type for a typical cost and resale recoup rate, stack up several renovations at once, and see a blended ROI — plus how a financed remodel compares with paying cash.
How this calculator helps
Renovation ROI is rarely a single-project question. Homeowners often plan a roof, a kitchen, and new windows within the same stretch of ownership, and each project category recoups a very different share of its cost at resale. This calculator lets you add a row per project, apply a type preset for a typical cost and recoup rate, and see one blended ROI across the whole plan instead of evaluating each upgrade in isolation.
Formula: Per-project value increase = project cost × typical recoup rate. Blended ROI % = ((total value increase − total project cost) ÷ total project cost) × 100. If financed, loan interest (from an amortized payment schedule) is added to the cost side before recalculating a financed ROI.
Assumptions: Type presets use commonly cited industry-average recoup ranges; actual resale value depends on local market conditions, project quality, and neighborhood demand, so treat every preset as a starting point you can override.
Worked example: A $13,000 roof replacement (60% recoup) plus a $26,000 minor kitchen remodel (65% recoup) costs $39,000 total and returns about $24,700 in value, for a blended ROI near -37% in cash — before factoring in the comfort and buyer-appeal benefits that don't show up in a resale number.
- Project type: Auto-fills a typical cost and resale recoup rate for that category of renovation.
- Cost and value increase: Both auto-fill from the preset but can be overridden with your own contractor quotes or appraisal estimates.
- Financing: Optional loan amount, APR, and term to see how borrowing costs change the real return.
What the result means
The blended ROI reflects your whole renovation plan, not just one project, which is more useful when several upgrades are happening within the same ownership period. A positive ROI suggests the plan may be financially defensible, while a negative result can indicate that the improvements are more about lifestyle value than resale value — most renovation categories do not recover their full cost at resale, so it is wise to weigh both financial and personal benefit.
When financing is enabled, the financed ROI is almost always lower than the cash ROI because loan interest adds to the cost side without adding to the resale value. A gap of just a few percentage points between the two is normal for a short-term, low-rate loan; a large gap is a sign that financing costs are eating a meaningful share of the project's expected return.
Typical ROI by project type
These are commonly cited industry-average ranges for the share of project cost recouped at resale. Actual recoup rates vary by region, home price tier, and finish quality, so use the type presets above as a starting point and adjust the cost and value fields with your own quotes when you have them.
| Project type | Typical resale recoup |
|---|---|
| Garage door replacement | ~85–95% |
| Siding replacement | ~65–75% |
| Window replacement | ~60–70% |
| Minor kitchen remodel | ~60–70% |
| Roof replacement | ~55–65% |
| Bathroom remodel | ~55–65% |
| Deck addition (wood) | ~45–55% |
| Major kitchen remodel | ~45–55% |

Frequently asked questions
- Does this include resale timing? No. It estimates a gain or loss based on value increase and project cost, not when the sale occurs.
- What if the blended ROI is negative? That can still be reasonable if the projects improve daily comfort, energy efficiency, or accessibility — resale recoup is only one part of the decision.
- Why would financed ROI be lower than cash ROI? Loan interest is a real cost that doesn't add to the home's resale value, so it reduces the return once it's included on the cost side of the calculation.
- Can I mix projects with different recoup rates? Yes — add one row per project and the blended ROI, recoup rate, and net gain all reflect the combined plan.
