Kitchen Remodel Calculator
Work out what a kitchen remodel will cost — line by line, with a contingency and tax, and the cost per square foot when you add the area.
Kitchens are the most expensive room to remodel, and the costs hide in eight different places. This calculator lists them all — cabinets to permits — and adds them up properly.
All prices are entered by you. This site publishes no construction prices, and results are estimates, not guaranteed quotes.
Your results
Enter your measurements and press Calculate.
Quantities are rounded up to whole tiles, planks, boxes or bags, after the wastage allowance. Cost appears only when you enter a price.
Formula
All lengths are converted to a single unit before the calculation: 1 ft = 0.3048 m, 1 in = 25.4 mm, 1 ft² = 0.09290304 m², 1 yd² = 9 ft². Material quantities are rounded up — you cannot buy part of a tile, plank or bag.
How to use this calculator
- Enter your cost for each line item (0 if not included).
- Set a contingency — 10–20% is normal.
- Enter your local tax rate.
- Add the kitchen area if you want a cost per square foot.
Worked example
| Line items | Cabinets $8,000 + Countertops $3,000 + Appliances $4,000 + Flooring $2,000 + Plumbing $1,500 + Electrical $1,200 + Labour $6,000 + Other $500 |
|---|---|
| Subtotal | $26,200 |
| Contingency (10%) | $2,620 |
| Tax (8%) | ($26,200 + $2,620) × 0.08 = $2,305.60 |
| Total | $31,125.60 |
| Cost per ft² (150 ft² kitchen) | $31,125.60 ÷ 150 = $207.50 per ft² |

Frequently asked questions
What is the biggest cost in a kitchen remodel?
Usually the cabinets — often 30–40% of the total — followed by labour and appliances. Enter your own quotes above; this calculator adds them up and shows the total.
How much does a kitchen remodel cost per square foot?
It varies hugely by finish level. Enter your line items and area above and the calculator gives your cost per square foot — from your numbers, not a guessed average.
Should I include a contingency for a kitchen?
Yes — 10–20%. Kitchens hide surprises: old wiring, plumbing in the wrong place, uneven floors. The contingency is cheaper than stopping the job halfway.
Are these figures a quote?
No. They are estimates built from your own numbers — not guaranteed quotes. Get written quotes from contractors for the real price.
