build budget goes.
Enter your total custom build budget to see a typical DFW cost breakdown across site work, framing, mechanicals, finishes, and more.
Splits are based on NAHB's national Cost of Constructing a Home survey (hard-cost categories), with a 10% contingency layered on top per standard custom-build guidance. Actual breakdowns shift with lot conditions, finish level, and market.
Typical budget breakdown.
Planning estimate only. These are typical splits, not a quote - actual costs vary by market, lot, and finish level.
Interior finishes (flooring, cabinets, countertops, fixtures, paint) typically account for around 30% of a custom build budget, making it the single largest category and the one with the most room to flex based on the finish level you choose.
A contingency, usually around 5% of the total budget, covers unforeseen site conditions, material price changes, or scope adjustments that come up during construction. Skipping it is one of the most common reasons custom build budgets run over.
Yes. A difficult lot can push site prep and foundation costs higher, and a high-end finish level shifts more of the budget toward interior finishes and mechanicals. These splits are a planning starting point, not a fixed formula.
