Countertop Calculator: $1,320 for a 10 ft Kitchen Top
On the defaults — a 10 ft by 2 ft top, $60 per square foot, 10% waste — your countertop costs $1,320.00. This is the countertop tool: measure the run once, allow for the cut-outs, and price the top once — a half-priced kitchen waits for no second quote.
What does countertop cost $1,320.00 mean?
It means one thousand three hundred and twenty dollars buys a 10 ft by 2 ft kitchen top once cutting waste is allowed for. The top itself is 20 square feet; with 10% waste that becomes 22 square feet of top, and at $60 per square foot the cost is $1,320.00. The waste dollars are not spare stock exactly — they are the top the job consumes in sink cut-outs and end cuts, so a top priced without waste runs short at the last foot.

| Top area | length × depth | 20 sq ft — 10 × 2. |
| Area with waste | top area × (1 + waste ÷ 100) | 22 sq ft — 20 × 1.10. |
| Countertop cost | area with waste × price per sq ft | $1,320.00 — 22 × $60. |
Three things to check before you trust the number
First, check the price figure on the supplier quote: $60 per square foot is a planning figure for a mid-range top, but stone and laminate sit far apart — at $80 this top costs $1,760.00, not $1,320.00. Second, measure the run itself, not the wall behind it: the cost follows the top area, and an L-shaped top is two runs added together, not one long run. Third, judge the waste honestly: a straight run fits 10%, but a top with a sink cut-out and an angled end can want 15%, since every cut-out is top consumed.
Worked example
10 ft long, 2 ft deep, $60 per square foot, 10% waste. Top area: 10 × 2 = 20 sq ft. With waste: 20 × 1.10 = 22 sq ft. Cost: 22 × $60 = $1,320.00. In practice that means budgeting $1,320.00, and expecting the waste dollars to go on the sink cut-out and the end cuts. If the same top used $80 per square foot instead, the cost would rise to $1,760.00 with waste, but the top covered would be identical.
Every branch, checked
With a 12 ft long top instead of 10 ft, the area rises to 24 sq ft and the cost to $1,584.00 with waste. With a 2.5 ft deep top, the area rises to 25 sq ft and the cost to $1,650.00 with waste. With $80 per square foot, the area stays 20 sq ft but the cost rises to $1,760.00 with waste. With 0% waste, the area stays 20 sq ft and the cost falls to $1,200.00. Top size, price and waste each move the cost on their own, so a wrong price figure is as costly as a wrong measurement.
The reverses, worked backwards
The length behind $1,320.00 is 10 ft: at 8 ft the cost is $1,056.00 (17.6 sq ft with waste, 8 ft × 2 ft, $60 per sq ft, 10% waste); at 12 ft it is $1,584.00 (26.4 sq ft with waste, 12 ft × 2 ft, $60 per sq ft, 10% waste). The depth behind $1,320.00 is 2 ft: at 1.5 ft the cost is $990.00 (16.5 sq ft with waste, 10 ft × 1.5 ft, $60 per sq ft, 10% waste); at 2.5 ft it is $1,650.00 (27.5 sq ft with waste, 10 ft × 2.5 ft, $60 per sq ft, 10% waste). The price behind $1,320.00 is $60: at $40 the cost is $880.00 (22 sq ft with waste, 10 ft × 2 ft, $40 per sq ft, 10% waste); at $80 it is $1,760.00 (22 sq ft with waste, 10 ft × 2 ft, $80 per sq ft, 10% waste). Each reverse moves one input and holds the rest, so the step is exactly one dimension or one price change.
What the defaults assume
The defaults assume a 10 ft straight kitchen run, 2 ft deep, $60 per square foot fitted, and 10% cutting waste. They do not assume the sink, the tap, the backsplash, edging or fitting labour — a top with a sink needs the sink bought separately, and fitting is priced by the job, not by the square foot.
Who uses this
- A homeowner budgeting a kitchen refresh: the $1,320.00 figure settles the top line before the supplier is called.
- A DIY builder pricing a new kitchen: the same maths on the run alone gives the top cost, not a whole kitchen.
- A contractor quoting a job: top area, price, waste — the quote follows the same three steps, and the waste line shows the client why.
- A landlord budgeting a kitchen refit: the run size off the plans, times depth, gives the top line on the refit budget.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the price-per-square-foot figure and the waste allowance. Real tops have sink cut-outs, angled ends and joins, and the supplier quote overrides any planning figure; a top measured gross over-orders, and a price read off a different material under-orders. Treat $1,320.00 as the planning cost for a 10 ft by 2 ft top at $60 per square foot, and raise the waste to 15% for a top with a sink cut-out and an angled end.

Frequently asked questions
How much does a 10 ft countertop cost?
$1,320.00 at $60 per square foot with 10% waste. The top is 20 sq ft; with waste that is 22 sq ft, and 22 × $60 = $1,320.00.
How many square feet is a 10 ft by 2 ft countertop?
20 sq ft: length times depth. With 10% waste the billable area is 22 sq ft, which is the figure the cost follows.
How much waste should I allow for a countertop?
10% for a straight run, 15% for a top with a sink cut-out and an angled end. Waste is the cutting, not spare stock.
Does this count the sink too?
No — this calculator counts the top only. The sink, tap and backsplash are bought separately, and fitting is priced by the job.
Should I price the exact area or add waste?
Add waste: the supplier cuts from a larger slab, and the cut-outs consume top. A top priced to the exact area runs short at the last foot.
How do I price an L-shaped countertop?
Add the two runs together as separate rectangles, then work from the total area. The tile calculator uses the same add-the-rectangles logic for a floor.
