State-adjusted budget ranges in under a minute, with the full formula and assumptions documented on our Methodology page.
A downloadable budget spreadsheet gives you rows and formulas, but no actual prices — you still have to go find current material costs and local labor rates yourself before the template is useful. Our calculators start from a configured baseline cost per project type and apply a state multiplier automatically, so you get a Low / Average / High range immediately, without manual research or building formulas from scratch.
That baseline isn't a live market feed — it's a set of figures we configure from publicly available industry cost ranges and review periodically. We say exactly how on the Methodology page, because a budgeting tool that hides its assumptions isn't very useful for actually comparing contractor bids.
Common questions about how our calculators work, cost accuracy, and how to use state-adjusted estimates.
Project Budgeter is a free set of interactive calculators for estimating home improvement costs — roofing, kitchen and bathroom remodels, decks, siding, HVAC, and more. Each calculator combines a configured baseline cost with your project size, material tier, and state to produce a Low / Average / High budget range. It's a planning aid, not a replacement for a contractor's written quote.
A downloadable spreadsheet template gives you a structure but no numbers — you still have to research pricing yourself. Our calculators start with configured baseline material and labor figures and a state cost multiplier already built in, so you get a usable range immediately without hunting down prices or building formulas.
Broadly: (1) define the project scope; (2) estimate the materials and labor each part of the job needs; (3) get localized pricing for your area (our calculators are one way to do this quickly); (4) add permit and disposal costs; (5) add a 10–15% contingency reserve for the unexpected; and (6) write it all down as a baseline you can compare actual spending against.
Track actual invoices against your baseline as they come in, keep your contingency reserve for genuinely unforeseen issues (not scope creep), and get any change to the original scope priced and approved before work continues — that's the single biggest source of budget overruns.
Pause and identify exactly where the overrun is coming from before authorizing more spending. Then: see if any remaining scope can be simplified or deferred (value engineering), ask whether material or labor substitutions could close the gap, and use your contingency reserve deliberately rather than letting it get absorbed item by item.
Select your project type, customize room dimensions and materials, and choose your US state for instant localized cost estimates.
