What a remodel budget has to cover
Materials are the easy part to price. The overruns come from the lines people leave off: disposal, tool rental, permits, the sheet of plywood you need after finding rot under the toilet. That is why a contingency line is not optional. Older houses routinely hide wiring, plumbing or framing that has to be brought up to current code once it is exposed.
If you are weighing DIY against hiring out, get at least two written quotes for the labor on each trade and enter them in the labor box. The quote tells you what your weekends are worth on this job.
Remodel cost questions
How do I estimate the cost of a remodel?
List every material with a quantity and a local price, add tools and permits, then add a contingency of 10–20% for surprises behind walls and under floors. If you are hiring out any part, add those quotes as separate lines.
How much contingency should I add?
10% for cosmetic work in a newer house, 15–20% for older homes or anything that opens walls, floors or plumbing. It is money you plan to spend on problems you cannot see yet.
Are the default prices accurate for my area?
They are round starting points, not quotes. Prices vary by region, brand and season. Replace them with prices from your store’s website or your contractor’s quote before you rely on the total.
What costs do DIYers forget?
Tool rental and blades, disposal or a dumpster, permit fees, delivery charges, shims, fasteners and adhesives, and a second trip for the thing that broke on demolition day.
