Project

Materialsquantity × unit price × waste

Enter what you'll actually buy. Waste covers offcuts, breakage and over-ordering — beginners forget it and eat the cost. Typical: lumber 10%, tile 10–15%, drywall 10%, paint 5%.

Labor (your crew)hours × rate

Use your true cost per hour, not what you pay in wages. Payroll burden below adds taxes, workers' comp and insurance on top. Subcontractors go in their own section — they aren't your payroll.

Subcontractors & other costs

Sub quotes go here (electrician, plumber). “Other” is equipment rental, dumpster, permits and other pass-through costs. Most builders mark subs up less than their own work — you'll set that below.

Sales / use tax

Construction is taxed differently in every state. Pick how your state treats it and enter your combined state + local rate. This is not tax advice — confirm your rule with your state Department of Revenue or your accountant.

Overhead, contingency & markup

Markup is what you add to each cost to get your price. Set it per category — most builders charge more on materials than on subs. Overhead is your cost of being in business (truck, phone, insurance, software) that no single job pays for directly; your markup has to beat it or you lose money while looking busy.
