Home Renovation ROI Calculator

About this calculator

Renovation ROI measures how efficiently a project turns money spent into resale value added, calculated as (added resale value − renovation cost) ÷ renovation cost × 100. Real-world data (like Remodeling Magazine's annual Cost vs. Value report) consistently shows this varies enormously by project — a minor kitchen remodel or garage door replacement often recoups 70-100%+ of its cost, while a high-end master suite addition may recoup well under 50%.

This calculator takes your renovation's total cost and the added resale value it's expected to generate and returns the ROI percentage and payback picture. Home flippers and real estate investors use it to rank which upgrades to prioritize on a budget, and homeowners planning a sale use it to decide whether a renovation is worth doing before listing versus letting the buyer handle it.
