About DIYCalcKit

What Is DIYCalcKit?

DIYCalcKit is a free collection of home improvement calculators covering paint, flooring, tile, renovation costs, fencing, garden beds, moving, and more. Every tool is designed to give homeowners a fast, accurate answer — no signup, no fees, no upsells.

We built DIYCalcKit because planning a home project shouldn't require spreadsheets or math degree. Whether you're figuring out how many gallons of paint to buy or estimating what a bathroom remodel will cost, we want to give you the right number in under 60 seconds.

How the Calculators Work

Our calculators use industry-standard formulas — the same math contractors and suppliers use. For cost estimators, we use national averages from sources including the Remodeling Magazine Cost vs. Value Report and contractor rate surveys. Estimates are updated annually.

All calculations run in your browser — nothing is sent to a server. Your measurements stay private.
