Introduction
Hypothetical case study — illustrative example, not a real project. The numbers below are constructed to demonstrate the estimating method with internally consistent arithmetic, not drawn from any actual remodel. Use it as a worked template: substitute your own measurements and local prices, and run them through the Kitchen Remodel Cost Calculator to build your real budget.
The scenario: a mid-range remodel of a 12 × 14 ft (3.66 × 4.27 m) kitchen — 168 sq ft (15.6 m²) of floor area — keeping the existing layout. Semi-custom cabinets, quartz counters, a mid-range appliance package, updated plumbing and electrical in place, new tile floor, and fresh paint. No walls move; the work triangle stays put. Component pricing follows the typical ranges in the cost guide.
The Scope
- Cabinet run: 22 linear ft (6.71 m) — L-shape, 14 ft (4.27 m) wall plus 8 ft (2.44 m) wall, no appliance openings in the measured run
- Countertop: 45 sq ft (4.18 m²) including a 3 × 6 ft (0.91 × 1.83 m) island
- Appliances: 30-in (76 cm) range, 36-in (91 cm) refrigerator, dishwasher, over-range microwave — mid-range package
- Trades: plumbing and electrical updated in place; no relocations
- Finishes: tile floor over 168 sq ft (15.6 m²), backsplash, drywall repair and paint
- Permits: combined remodel permit with electrical and plumbing inspections
Line-by-Line Estimate
| Line item | Calculation | Cost |
|---|---|---|
| Cabinets (semi-custom) | 22 linear ft × $400/ft | $8,800 |
| Countertops (quartz) | 45 sq ft × $70/sq ft | $3,150 |
| Appliance package | Flat package price | $6,500 |
| Sink, faucet, fixtures | Flat | $900 |
| Plumbing (in place) | Flat job price | $1,800 |
| Electrical (in place) | Flat job price | $2,400 |
| Flooring (tile) | 168 sq ft × $12/sq ft | $2,016 |
| Drywall repair and paint | Flat | $1,400 |
| Backsplash | Flat | $1,100 |
| Permits | Flat | $800 |
| Component subtotal | Sum of above | $28,866 |
Subtotal check: $8,800 + $3,150 + $6,500 + $900 + $1,800 + $2,400 + $2,016 + $1,400 + $1,100 + $800 = $28,866 ✓.
Applying the Labor Share
Labor at 30% of the total project: total = $28,866 ÷ (1 − 0.30) = $28,866 ÷ 0.70 = $41,237. Labor = $41,237 − $28,866 = $12,371. Check: $28,866 + $12,371 = $41,237 ✓, and $12,371 ÷ $41,237 = 30.0% ✓. The derivation is in the formula-explained guide.
Unit Cross-Checks
- Cabinets: 22 ft × 0.3048 = 6.7056 m ≈ 6.71 m ✓; $8,800 ÷ 6.7056 m ≈ $1,312/linear m — inside the semi-custom band ($492–$2,133/linear m) ✓
- Counters: 45 sq ft × 0.0929 = 4.1805 m² ≈ 4.18 m² ✓; $3,150 ÷ 4.1805 m² ≈ $754/m² — inside the quartz band ($538–$1,076/m²) ✓
- Flooring: 168 sq ft × 0.0929 = 15.607 m² ≈ 15.6 m² ✓; $2,016 ÷ 15.607 m² ≈ $129/m² ✓
Contingency and Final Planning Budget
Ten percent contingency on $41,237 = $4,124, giving a final planning budget of $45,361 (round to $45,400 for planning). Home-value check: on a $450,000 home, the 5–15% guideline gives $22,500–$67,500 — $45,400 sits comfortably inside it.
Budget Share Analysis
| Category | Amount | Share of $41,237 |
|---|---|---|
| Cabinets | $8,800 | 21.3% |
| Counters | $3,150 | 7.6% |
| Appliances + fixtures | $7,400 | 17.9% |
| Plumbing + electrical | $4,200 | 10.2% |
| Flooring, paint, backsplash, permits | $5,316 | 12.9% |
| Labor | $12,371 | 30.0% |
The shares look healthy: no single component dominates, labor sits at the standard 30%, and cabinets — the biggest material line — stay well under 40% of the total. Note what this scenario deliberately excludes: no layout changes (which would add $5,000–$15,000 in trade work), no custom cabinetry (which would roughly double the cabinet line at $800/linear ft), and no professional-grade appliances (which could add $5,000–$8,000 to the package). Each of those choices would move the project into the upscale tier — which is exactly why the 5–15% home-value check matters: it catches scope creep while the numbers are still on paper. If this were a real project, the next step would be three contractor bids against this written scope, per the remodel checklist.

Frequently Asked Questions
Is this case study based on a real kitchen remodel?
No. It is explicitly a hypothetical, illustrative example constructed to demonstrate the estimating method. All numbers are internally consistent, but they are not drawn from any actual project — substitute your own measurements and local prices.
What would change the total most in this example?
Moving any plumbing or gas fixture: layout changes add $5,000–$15,000. Upgrading to custom cabinets at $800/linear ft would add $8,800 to the cabinet line alone.
Why is the contingency only 10% here?
Because the scenario keeps the existing layout with in-place trade work — the lowest-risk profile. Older homes or layout changes warrant 15–20%.
How do the budget shares compare to typical benchmarks?
Cabinets at 20.6% sit below the typical 25–35% band (this scenario uses mid-range semi-custom, not premium), labor at 30% is textbook, and no category exceeds 40% — a balanced mid-range profile.
What should I do with this template?
Replace every measurement and price with your own, keep the arithmetic structure (subtotal → labor division → contingency → home-value check), and run the result through the calculator to verify.
Sequencing This Scenario
The order of work matters as much as the prices: demolition and rough-in (plumbing, electrical) first, then drywall and flooring prep, then cabinets, then counters, then appliances and finish plumbing. Measuring twice before ordering cabinets prevents the most expensive rework — a box that doesn’t fit the rough-in costs more than the box itself. Lock the layout before rough-in begins, because every change after that point multiplies through the trades.
Get Your Number
This hypothetical totals $41,237 before contingency ($45,361 with 10%) — every line item shown, every sum verified. Your kitchen will differ in measurements, materials, and market; the method won’t. Enter your own numbers into the Kitchen Remodel Cost Calculator, apply the same four steps (components → labor share → unit cross-checks → contingency), and take the result to local contractors for quotes.
