Free, no account needed
Set up a free home profile with your country, units and currency, add your rooms and their measurements, and keep a spec book of what's in each one. Every calculator, cost estimate and maintenance job then works from your actual house.
Most home calculators ask for the same numbers every time: room sizes, ceiling height, where you live. My Home keeps them in one place. Measure a room once and the paint, flooring, tile and drywall calculators prefill from it, in metric or imperial depending on your country.
Your country also sets the currency and a local cost index, so renovation estimates come out in prices that make sense where you are. You can tune the index any time if your quotes run higher or lower.
