Plan Your Improvements
Renovation ROI Calculator
Explore how your renovation costs and estimated increase in home value could shape your potential return on home improvements.
Your project. Your next step.
See whether a renovation could pay off.
Enter your project costs and the value you expect the renovation to add. Then select Calculate Renovation ROI to estimate its financial impact compared with selling without the project.
Planning estimate only. Value added is your assumption, not an appraisal or guaranteed return. Actual costs and resale results may differ.
Beyond the renovation budget
Understand your renovation’s potential return.
This calculator compares renovating with selling without the project. Your expected sale price change, renovation budget, and additional carrying expenses determine whether the project shows an estimated gain or loss.
Your value assumption
Cost versus added value
Your renovation budget and expected increase in sale price are separate inputs. Spending more does not automatically add more value; the calculator uses the sale price change you enter.
Starting home value is used only to show the projected value after renovation. Changing it alone does not change project ROI. You can also model no added value or a decrease.
Your additional expenses
Selling costs & delays
The selling-cost percentage applies only to the change in sale price. Additional carrying expenses equal the extra months caused by the project multiplied by your monthly expense estimate.
Include delay-related interest, taxes, insurance, and utilities, but exclude mortgage principal and costs already in the renovation budget. A longer delay increases modeled costs when monthly carrying expenses are greater than zero.
Your project result
Net gain & project ROI
Net gain is the assumed sale price change after selling-cost adjustments, minus renovation and additional carrying costs. ROI divides that gain by the combined project and carrying costs.
A negative result means the project leaves you behind selling without renovating under these assumptions. This is a project return, not an annual return or total seller proceeds. ROI displays N/A when combined costs are zero.
Compare a few possibilities.
- Calculate your starting scenario and note the estimated net gain or loss and project ROI.
- Adjust one input, such as the renovation budget, expected sale price increase, or extra months before selling.
- Select Calculate Renovation ROI again and compare the updated results with your starting point.
Added value is your assumption, not an appraisal. The comparison assumes the same selling-cost percentage in both scenarios and excludes taxes on gains, market appreciation, and expenses not entered.
A little more clarity
Questions about your renovation return?
Here’s how the calculator compares renovating with selling as-is, including how your expected value increase, project budget, and added time affect the estimate.
Does this show my total proceeds from selling?
No. It estimates the renovation’s added financial impact compared with selling without the project. Net gain or loss subtracts added selling costs, renovation spending, and additional carrying expenses from the assumed sale price increase. ROI divides that result by total project and carrying costs. It is a project return, not an annual return.
Does the calculator determine how much value my renovation adds?
No. The expected increase in sale price is your assumption; the calculator does not analyze comparable sales or automatically value improvements. Renovation cost does not determine value added. The starting home value only helps show the projected home value—it does not change the project’s ROI.
Why are selling costs applied only to the added value?
The comparison assumes the same selling-cost percentage whether you renovate or sell as-is. Only the change in those costs affects the renovation’s added return.
Enter your assumed combined percentage for commission and other costs tied to sale price. The example percentage is not a recommended rate. Taxes on gains and unentered expenses are excluded.
Which carrying expenses should I include?
Include expenses caused by the extra time before selling, such as mortgage interest, property taxes, insurance, and utilities. Exclude mortgage principal and costs already included in your renovation budget.
Use only the additional months caused by the project, not your entire ownership period. The calculator multiplies those months by your monthly carrying expenses. Partial months are allowed.
How do I update my estimate?
After editing your inputs, select Calculate Renovation ROI. Results stay based on your last successful calculation until you calculate again.
Reset example restores the starting inputs without changing existing results. Select Calculate Renovation ROI again to update them. Starting values are examples, not contractor quotes or guaranteed resale outcomes.
