Investment ROI
The Investment ROI panel (also called the breakeven calculator) gives you a rough, data-informed estimate of how much of a renovation's cost is likely to come back as added home value. It appears as an expandable card on the estimate editor and as a compact or full summary on proposals and estimate previews.
Every Investment ROI figure carries this exact disclaimer in the app, because it is the single most important thing to understand about this feature. It is a data-informed estimate built from national averages and whatever comparable-sale or home-value data is available for the property — never a certified appraisal, and never a promise of what the home will actually sell for.
How It's Calculated
Investment ROI estimates two independent things and reports the more conservative of the two:
- What this type of project typically returns. A national, judgment-based percentage (the "recoup rate") for the project type and finish tier, applied to the renovation cost. For example, a mid-range bathroom remodel might be estimated to recoup a majority of its cost at resale — the exact rate varies by project type and finish level, and is shown in the "How this is calculated" expander on the panel itself.
- What the neighborhood or the home's own value can support. A ceiling on how much value this specific home can realistically gain:
- When there are enough recent, trustworthy nearby comparable sales ("comps") for the property, the ceiling is based on what those nearby sales actually support — a data point drawn from real recent transactions near the subject property, not a national number.
- When there are not yet enough nearby comps, the ceiling instead falls back to a modest allowance above the home's own current value — used only because comp data isn't available yet, and clearly labeled as such in the app ("Estimate based on home value only (no comps yet)").
The panel shows plain-language labels for these, not internal names:
| In-app label | What it measures |
|---|---|
| Typical cost recovered | National averages for how much of this project type typically gets recouped. |
| Nearby home sales | What recent nearby comparable sales support. |
| This home's own value | A share of this home's current value — used when there isn't enough nearby sales data yet. |
Why the lower number is used
The headline figure you see is always the more conservative (lower) of the two figures above — never the higher one. This is a deliberate choice: showing the higher of two uncertain estimates would overstate what a homeowner can expect, and the whole point of this feature is to avoid a number a contractor might repeat to a homeowner that the underlying math cannot actually support. When the neighborhood/home-value ceiling is the smaller number, the panel says so plainly — for example, "What nearby sales support was the more conservative of the two, so that's the number shown above" — rather than implying something "capped" an otherwise bigger number.
Spending beyond the typical range
Spending significantly more than is typical for a project type on a given home (over-improvement) does not recoup at the same rate as normal in-range spending. Dollars spent beyond the typical range for a project type are estimated to recoup at 15% of that project's normal recoup rate — not a flat 15%, and not the full recoup rate. For example, on a project type/finish level typically recouping 80%, over-improvement dollars are estimated to recoup at roughly 12% (80% × 15%), not 15% outright. This is a general rule of thumb for diminishing returns on over-improvement, not a measured market rate for this specific home. The panel flags this explicitly as "⚠ Over-improvement for the neighborhood" when it applies.
The Confidence Band
Every Investment ROI result carries a confidence level — HIGH, MEDIUM, or LOW — and a dollar range, not a single guaranteed number. The range widens as confidence drops:
- HIGH confidence — enough trustworthy nearby comparable sales exist to ground the neighborhood ceiling in real recent transactions, and nothing else about the inputs is flagged as uncertain. This carries the narrowest range.
- MEDIUM confidence — typically a "cold start": there are not yet enough nearby comps, so the estimate leans on the home's own current value instead. Carries a wider range than HIGH.
- LOW confidence — applies when the project is over-improving for the neighborhood, the project type could not be classified and fell back to a generic estimate, a required input (like finish tier) was missing, or the project type doesn't yet have its own calibrated recoup benchmark. Carries the widest range.
The range exists because this is genuinely a range of plausible outcomes, not a single precise prediction. Treat the low and high ends as the honest boundaries of what the underlying data supports — not the point estimate alone, and never as two numbers you should average into a single promise.
The projected home value shown alongside the estimate is also a range (a "current value" band, not a single point) for the same reason: the home's current value itself carries some uncertainty from the underlying data source, and the projected range accounts for that uncertainty on top of the value-add estimate.
What This Is NOT
- Not an appraisal. No licensed appraiser has valued this property or this renovation. Nothing about this figure meets the standard of, or should be represented as, a formal appraisal.
- Not a guarantee of resale value. The figures are estimates built from national averages and, where available, real nearby comparable sales — not a promise of what the home will sell for after the renovation.
- Not a certified inspection or valuation of any kind. This tool does not inspect the property, verify its condition, or certify anything about it.
- Not yet calibrated to ContractorScope AI's own outcomes. The recoup percentages behind this estimate are national judgment benchmarks, not yet calibrated against ContractorScope AI's own closed-job resale outcomes. They are the best available default, not a validated prediction specific to your market or your work.
What a Contractor May Safely Tell a Homeowner
- "Based on national averages and what we can see about your neighborhood, this type of project typically recoups roughly this range of its cost at resale — it's a rough, data-informed estimate, not a guarantee."
- "This isn't an appraisal. If you want a precise number for what your home is worth or would be worth after this work, you'd want a licensed appraiser."
- "The range is wide because [there isn't much recent sale data for this neighborhood yet / this is a bigger project than typical for this home], so treat it as a ballpark."
What a Contractor Should NOT Claim
- That this is an appraisal, or that it meets any appraisal standard.
- That the home is guaranteed to sell for the projected value, or to recoup the stated percentage of project cost.
- That the point estimate (rather than the range) is a precise, certain number.
- That the recoup percentages are calibrated to your specific business, market, or past jobs — they are national defaults today.
