Home Improvement ROI Calculator

Garage door replacement is the highest-ROI home improvement in the data: 97%. You spend about $4,300 and add $4,175 in resale value. Effectively you're getting a new garage door for $125. No other project in this dataset comes close in terms of ROI efficiency.

Manufactured stone veneer comes in second at 92%. Adding stone veneer to the front of a house costs $8,000–$12,000 and adds $10,186 in value nationally. Northeast buyers respond especially well to it — 92% ROI in that region. It's an exterior project with outsized curb appeal impact relative to cost.

Minor kitchen remodels return 72% nationally. Basement remodels return 70%. New flooring returns around 70%. These are the interior projects that make sense financially. All involve meaningful improvements to spaces buyers see and use, without the diminishing returns that come with full gut renovations.

Major kitchen and bathroom remodels return 56–62% at mid-range, dropping further at upscale. A $76,000 upscale bathroom remodel recovers $43,000 at sale — a net cost of $33,000. That's fine if you're staying 10 years and will enjoy the bathroom daily. It's a poor financial decision if you're selling in two years.

ROI data here comes from Remodeling Magazine's annual Cost vs. Value Report, which surveys Realtors in 100+ markets on how much each project type increases resale value. It's the most widely cited source for renovation ROI in the industry. The numbers represent a mid-range quality execution — budgeting below mid-range doesn't meaningfully improve ROI because the value added is lower too.

If you're staying in your home for five years or more, ROI is the wrong metric. You should also be counting the value of using the improved space. A new kitchen you cook in daily for 10 years has personal value beyond resale. A finished basement your family actually uses is worth more than 70% of its cost in use.

The ROI calculator is most useful for one decision: figuring out whether a renovation pays for itself before you sell. If you're planning to list within 18 months, focus on projects above 65% ROI. Garage door replacement, stone veneer, minor kitchen updates, window replacement, and deck additions all clear that bar. Major room additions ($100,000+) return 54% — you'll spend more than you'll recover.

State location adjusts the value added proportionally here. A project that adds $16,000 in national average value adds $21,600 in a 1.35x state like California, and $11,520 in a 0.72x state like Mississippi. High-cost states have higher home values, so the same physical improvement generates more dollar value at sale.

One thing this calculator can't account for: condition. A renovated kitchen in a house with a 30-year-old roof and original windows may add less than projected because buyers factor in deferred maintenance. Renovations add the most value when the rest of the house is already in good shape. Fix the fundamentals before upgrading finishes.
