Owner-Builder Calculators
Free, no-signup calculators to help you plan and price your build. Estimate your potential savings, material quantities, a realistic timeline, and keep your budget on track — each one is based on 15+ years of general contracting experience.
The Calculators
Cost Savings Calculator
See how much you could realistically save by acting as your own general contractor on your project.
Material Estimator
Estimate quantities and costs for the major materials — framing, concrete, roofing, drywall, and more.
Timeline Estimator
Plan a realistic build schedule and time commitment based on your home size and how much you DIY.
Budget Tracker
Track expenses against your budget phase by phase so overruns surface early instead of at the end.
