About the Home Renovation ROI Calculator
This home renovation ROI calculator estimates how much of a remodel’s cost you are likely to get back, and what your return on investment is, when you eventually sell. Enter the project cost, the value you expect it to add to the home once finished, how long you plan to stay, expected yearly home price growth and the selling costs (agent commission and fees) that eat into any extra sale price.
It is useful for homeowners deciding between projects — a kitchen versus a bathroom, an addition versus a loft conversion — and for anyone preparing a house for sale who wants to know whether an upgrade is worth doing first. The result shows the cost recouped as a percentage, the net gain or loss in dollars, a total and an annualised ROI, and a year-by-year chart of the added value against what you spent.
The value added is your estimate: get it from comparable sales, an appraiser or a local agent, because what a project adds varies widely by market and finish level. The calculator assumes the added value grows at the same rate as the rest of the home and ignores the enjoyment you get from the upgrade while you live there, financing costs and any tax effects.
With the default inputs, the return on investment is -18.3%. Change any value above to recalculate instantly.
How to use the home renovation roi calculator
- 1Enter the total renovation cost, including materials, labour and permits.
- 2Estimate the value the project adds using comparable sales or an appraiser.
- 3Enter how many years you expect to stay before selling.
- 4Set expected yearly home price growth and your selling costs.
- 5Compare the ROI and cost recouped — and weigh them against how much you will enjoy the upgrade.
Formula and method
The value the renovation adds today (V) is grown at the yearly home price growth rate (g) for the number of years until you sell (t). Selling costs (s), such as agent commission, are taken off that higher sale price because they are charged on the whole price, including the part created by the renovation. What is left is compared with the renovation cost (C).
Cost recouped is the net added value ÷ cost; ROI is the net gain ÷ cost. The annualised return is (net value ÷ cost)^(1/t) − 1, which lets you compare the project with other uses of the money. Financing interest, maintenance savings and tax are not included.

Worked examples
$40,000 kitchen remodel adding $30,000, sold after 5 years
The $30,000 added value grows at 3% a year to about $34,778 by the time you sell. Selling costs of 6% take about $2,087, leaving $32,692 — 81.7% of the $40,000 cost, an ROI of about −18%.
Cosmetic refresh before selling now
Paint, flooring and fixtures costing $8,000 that lift the sale price by $12,000 return $11,280 after 6% selling costs — a $3,280 gain and a 41% return.
$60,000 addition held for 15 years
The $50,000 of added value grows at 4% a year to about $90,047 after 15 years. After 5% selling costs you recover about $85,545, a $25,545 gain on the $60,000 cost — roughly 2.4% a year.
Frequently asked questions
Which home renovations have the best ROI?+
Smaller, lower-cost projects such as garage door or entry door replacements, minor kitchen updates and exterior refreshes usually recoup the largest share of their cost. Large luxury remodels and additions tend to recoup a lower percentage.
Do renovations ever pay for themselves?+
Sometimes — especially cosmetic fixes before a sale, projects that bring a dated home up to neighbourhood standard, or adding living space in high-demand markets. Many projects recoup well under 100%, so the rest is the cost of enjoying the upgrade.
How do I estimate the value a renovation adds?+
Compare recent sale prices of similar homes nearby with and without the feature, ask a local agent for a broker price opinion, or commission an appraisal. Avoid over-improving beyond what buyers in your area pay for.
Should I include selling costs?+
Yes. Agent commissions and closing costs are charged on the whole sale price, so they also reduce the extra money a renovation brings in. Leaving them out overstates the return.
Does financing change the ROI?+
Yes. If you pay for the project with a home equity loan, HELOC or personal loan, the interest you pay adds to the true cost and lowers the return. Add expected interest to the renovation cost for a fuller picture.
