Unit costs are national mid-range defaults. Overwrite them with your own — the price is only as good as the numbers you feed it.

How the rollup works

Each line splits into materials and labour using that trade's own labour share — drywall is 70% labour, cabinets are 30%. Burden is applied to the labour half only.
Direct cost = materials + burdened labour.
Contingency and then overhead are applied on top of direct cost.
Price = total cost ÷ (1 − margin). Margin is divided, not multiplied — a 20% markup only leaves a 16.7% margin.

Before you send it

This is a budget estimate, not a bid. It has no allowance for permits, engineering, bonding, winter conditions or anything specific to your site.
Renovation carries far more unknown than new build. If you cannot see behind the wall, 10–15% contingency is the honest number.
Get real subcontractor quotes before committing to a price. Defaults are a starting point for a conversation, not a substitute for one.
Write your exclusions down. Most disputes are about what was never in the estimate, not about what was.
