The shape of a kitchen materials budget
Every kitchen is different, but the proportions of a typical mid-range materials budget (materials only — labor is its own conversation) are surprisingly consistent:
| Category | Share of materials budget | Notes |
|---|---|---|
| Cabinets & hardware | 30–40% | The single biggest line in almost every kitchen. |
| Appliances | 15–25% | Swings hugely with brand tier. |
| Countertops | 10–15% | Material choice (laminate → quartz → stone) drives it. |
| Flooring & tile | 8–12% | Floor plus backsplash. |
| Plumbing & fixtures | 5–8% | Sink, faucet, disposal, valves. |
| Lighting & electrical | 4–7% | Fixtures, under-cabinet, recessed cans. |
| Paint, drywall & trim | 3–5% | Cheap materials, easy to forget entirely. |
| Everything else | 5–10% | Underlayment, fasteners, caulk, vents, outlet covers… |
The last row is where budgets quietly die. Cement board, waterproofing membrane, grout, transition strips, shims, and the second trip's worth of caulk are individually cheap and collectively real money. A budget that only lists the glamour items starts 10% underwater.
Estimated vs. actual — track both, separately
A useful renovation budget holds two numbers per item, not one:
- Estimated: price × quantity for everything still on the list. This is your planning number — it moves as you make selections.
- Actual: only what you've genuinely committed — items ordered, shipped, delivered, or installed. This is your real spend.
The gap between them is your remaining exposure. When people say a project "went over budget," what usually happened is the two numbers were never separated: window-shopping prices drifted up item by item, and nobody noticed because there was no committed-spend line to compare against.
A single "total spent" number counted the same whether an item was window-shopped, ordered, or installed will actively mislead you. Status matters: an item that's ordered is money committed; an item on a wish list is a decision you can still change.
Contingency: decide it before you need it
Set a contingency of 10–20% of the materials budget on day one and treat it as spoken for — kitchens hide surprises behind walls, from subfloor rot near the sink to wiring that isn't to code to a wall that isn't square by two inches. The full logic for sizing it is in the renovation contingency guide.
Three practices that keep a budget honest
- Build the budget from the checklist, not the other way around. Price every line of a complete item list — including the boring rows — and the total is a real number instead of a hope.
- Record the price when you order. The listed price and the paid price diverge (sales, shipping, substitutions). Your actual-spend column should reflect receipts, not listings.
- Review by phase, not just by total. If rough-in came in 15% over, finishes need to come in under — a phase-level view shows you that in time to adjust selections, which is the only lever a homeowner really has mid-project.
