What Will My Renovation Add to Home Value?
Choose a renovation, then replace the starting assumptions with your own project cost and expected resale value. No address or signup is required.
Renovation ROI Calculator
Test a renovation scenario before you commit
This calculator divides expected resale value added by project cost. Its starting values are BuildFolio planning assumptions, not observed quotes, market averages, an appraisal, or a promise of future value. Replace them with local evidence whenever you have it; your home value is optional and is used only for context.
Compare BuildFolio’s Starting Scenarios
These stored defaults make the calculator usable before you have local data. They are standardized planning assumptions, not a current cost survey or resale forecast.
Use the table as a set of editable scenarios. A higher modeled ratio means only that the stored resale-value assumption is closer to the stored project-cost assumption. It does not establish which renovation is best for your home, neighborhood, timing, or goals.
Once you have a contractor quote, enter that amount as project cost. Ask a local real estate agent or appraiser for evidence about likely resale value, and replace the value-added input too. That turns a generic starting scenario into a calculation based on your own evidence.

How the Renovation ROI Calculator Works
The calculator starts with a project cost and an expected resale value added. Both inputs remain visible and adjustable. It does not fetch an address, infer a home value, or apply a hidden regional multiplier.
If you add your current home value, the calculator shows the project cost as a share of that value and adds the modeled resale value to it. Home value does not change the ROI calculation or silently scale either project input.
The formula
- Modeled ROI percentage = Expected resale value added / Project cost × 100
- Modeled home value after the project = Current home value + Expected resale value added
- Project cost share = Project cost / Current home value × 100
A result above 100% means the value-added input exceeds the cost input. It is not a guaranteed profit, appraisal, sale price, tax result, or investment recommendation. Financing costs, maintenance, transaction costs, and the value of using the renovation are outside this simple formula.
Evidence That Can Improve Your Scenario
The model becomes more useful as you replace defaults with evidence tied to your property, scope, and local market. These six inputs are worth checking before treating any result as a budget or resale expectation.
Local Bids and Sale Comparables
Use written bids for the planned scope and recent comparable sales for resale context. A national or stored default cannot capture your labor market, materials, or buyer expectations.
Scope and Work Quality
Define what is included, excluded, repaired, and finished. Two projects with the same label can have different costs and buyer reactions because their scope and execution differ.
Neighborhood Fit
Compare the finished home with similar nearby properties. An upgrade that buyers expect in one segment may add little in another, so local comparables matter more than a generic ranking.
Timing and Condition
Market conditions, wear, maintenance, and changing preferences can alter how a future buyer values the work. Revisit the estimate when the scope or likely sale timing changes.
Operating Costs
Energy, insurance, repair, and maintenance effects are separate from resale value. Estimate those cash flows independently instead of folding them into the value-added input without evidence.
Permits and Documentation
Check permit requirements and retain contracts, approvals, warranties, and completion records. Clear documentation can help future buyers understand what was actually done.
ROI Is Only One Part of the Decision
Resale value does not measure comfort, accessibility, safety, avoided repairs, energy use, or the value of enjoying the project while you own the home. Keep those benefits separate so a simple resale ratio does not pretend to answer a broader decision.
If a sale is near, ask a local real estate professional which repairs or updates buyers are likely to notice and verify the likely resale effect. If you plan to stay, compare the project’s ongoing benefits and costs with other uses of the budget. In either case, use ranges and test more than one scenario.
Run a low, working, and high scenario
Start with the written project price, then test more expensive change-order cases. For resale value, try a conservative case as well as the number you consider most likely. The spread between scenarios is often more useful than a single percentage.
Use the property report to review available property facts and planning estimates. If a roof is in scope, review the roof-age evidence. If you have a contractor quote, use the quote tool to compare its scope and assumptions.
Frequently Asked Questions
What home renovation has the highest ROI?
There is no universal highest-ROI renovation. The result depends on the project cost and resale value you enter. The comparison table uses BuildFolio planning assumptions, not observed market averages, so replace them with local bids and resale evidence.
Is a kitchen remodel worth it for resale?
It can be, but this calculator cannot decide that from a project label alone. Compare a scope-specific bid with local resale evidence, and include the value you expect to get from using the renovated kitchen. Test conservative and higher-cost scenarios before committing.
How does my location affect renovation ROI?
Location can affect contractor pricing, permit requirements, comparable sales, and buyer expectations. This calculator does not infer a regional multiplier from your address or home value. Enter local bids and a local resale estimate to reflect those differences.
Should I renovate before selling my house?
Ask a local real estate professional which repairs or updates are likely to matter for your sale, then compare that evidence with written project bids and your timeline. A modeled ratio is not a recommendation to renovate, and transaction costs or delays may change the decision.
Where do the calculator defaults come from?
The defaults are standardized BuildFolio planning assumptions stored on this page. BuildFolio does not have a retained source URL or observed quote set that supports presenting them as current market averages. Use them only as editable starting points and replace them with real local data when available.
Does renovation ROI change over time?
Yes. Project scope, bids, market conditions, property condition, and buyer preferences can all change. Re-run the calculator with current evidence whenever your scope, likely sale timing, or local market changes.
