Kitchen Remodel Cost Calculator

Build a kitchen estimate around its specification

Kitchen spending follows the specification of the cabinetry, worktops and appliance package more closely than the room's floor footprint. A long run of simple cupboards can cost less than a short run with special pull-outs and custom joinery. This worksheet gives you separate supply quantities for cabinets and counters, then adds a package amount for appliances and a lump sum for installation and remaining scope. Every figure is supplied by you. The examples are arithmetic placeholders rather than advertised quotations or market data.

Use consistent definitions for each quotation

Cabinet run must match the way the supplier quotes. If the rate covers a paired base-and-wall arrangement, measure that arrangement once; if separate base and wall runs are priced individually, combine their lengths only with a compatible blended rate. A complete cabinet package quote can be represented by a rate derived from its total and the chosen run. Worktop surface area includes islands, peninsulas and breakfast bars that will be supplied. Sink cut-outs, edge profiles and joints may carry separate fabrication fees, so put those in the remaining scope allowance if they are not included in the countertop rate.

Example cabinetry and worktop budget

Eight metres of cabinet run priced at 600 per metre gives 4,800. Five square metres of countertop priced at 250 gives 1,250. An appliance package of 2,500 and installation allowance of 3,000 bring the subtotal to 11,550. Keeping a reserve of 10 percent adds 1,155, for a working budget of 12,705 currency units. Switching to imperial mode resets the sample quantity and rate fields; it does not convert currency or infer a new supplier quotation. Enter equivalent quantities and correspondingly converted rates when comparing the same project across units.

Check what remains outside the package

Write a schedule showing whether removal, flooring, splashbacks, decoration and waste handling are included. Service relocation, new sockets and ventilation may require specialist allowances, especially when the layout changes. Delivery, storage, replacement doors and damaged-item handling should also be clarified. Avoid adding an appliance again if it is already part of the cabinet supplier's package. Apply one currency and one tax basis across the worksheet; there is no automatic tax or exchange-rate calculation. The reserve covers possible unpriced changes, but it does not predict them. Retain dimensions, product references and quote exclusions alongside the estimate so you can revise the affected line when a design choice changes rather than replacing the entire budget with an unexplained new total.

A reproducible calculation with complete inputs

For a reproducible kitchen remodel cost calculator example, use the metric input system and enter Total cabinet run: 8 m; Cabinet supply rate: 600 currency/m; Countertop surface area: 5 m²; Countertop supply rate: 250 currency/m²; Appliance package: 2500 currency; Installation and remaining scope: 3000 currency; Contingency reserve: 10 %. These settings describe one specific scenario, not a new default for every job. The result follows the method and allowances already explained above. Keep the entire set of values when comparing it with a hand calculation; omitting a selected material or an allowance can change the result even when the dimensions match. The following rows show the unrounded calculation values alongside the precision used by the interface.

How should I prepare these entries?

Total cabinet run: enter the value in m. Cabinet supply rate: enter the value in currency/m. Countertop surface area: enter the value in m². Countertop supply rate: enter the value in currency/m². Appliance package: enter the value in currency. Installation and remaining scope: enter the value in currency. Contingency reserve: enter the value in %. Choose the unit system before transferring your measurements. A depth, length, area and coverage can have different field units even within one system. Read each label individually rather than entering the same unit convention in every box. Optional openings or allowances should describe your actual scenario instead of being silently left at a sample value. The worked inputs above identify exactly which selections produced the table.

How should I compare another measurement?

Change one measurement or option at a time and keep the other inputs fixed. The new result reflects the whole stated formula, including its conversions, allowances and purchase rounding. A quantity that depends on several dimensions does not necessarily respond linearly to every field. Compare intermediate area or volume outputs when present before interpreting the final rounded purchase quantity. This makes a misplaced unit easier to detect than judging the final total alone. Record the selected unit system beside each scenario so that a copied number is not silently reused under different field units.
