Quick Start
Tip: A 15% contingency is built in. Kitchen renovations often uncover hidden plumbing, electrical or structural issues once old cabinetry is removed. Always get at least two or three quotes before committing.
Project
Kitchen Details
Kitchen type is used for project context only. Cost is calculated from area, scope, trades and add-ons.
Scope & Market
Market cost level adjusts for local labour and supply differences, roughly ±35% from the average baseline. Currency selection converts the output using approximate exchange rates.
Trades
Select the trades involved. Only selected trades are included in the estimate, even if the renovation scope description mentions additional work. Cabinetry, plumbing, electrical and tiling use a minimum of 6 m² to account for fixed costs that don't scale with very small kitchens.
Optional add-ons
How kitchen renovation costs are calculated
How the estimate works
This calculator applies typical cost ranges per m² for each selected trade at the chosen scope level, then adjusts for your local market cost level and converts to your selected currency using approximate exchange rates.
Minimum effective area
Cabinetry, plumbing, electrical and tiling include significant fixed costs that do not scale with kitchen size. Fitting a run of cabinets, connecting a sink and dishwasher, or running new circuits for appliances carries broadly similar labour whether the kitchen is 6 m² or 12 m². To reflect this, the calculator uses a minimum effective area of 6 m² for these four trades, regardless of the size you enter. This prevents unrealistically low estimates for very small kitchens.
Cabinetry and worktops
Cabinetry and worktops are usually the single largest cost in a kitchen renovation. The rate you select depends on scope: refacing or repainting existing cabinet doors sits at the low end, while bespoke joinery and premium stone worktops sit at the high end. Getting a firm cabinetry quote early is the most reliable way to pin down your overall budget.
Contingency
A 15 percent contingency is applied to all kitchen renovations. This reflects the risk of hidden issues found once old cabinetry and flooring are removed, such as outdated wiring, damaged subfloor or pipework that needs rerouting. A common rule of thumb is 10 to 20 percent for renovations generally. For kitchens, 15 percent is a reasonable starting point.
What this estimate does not include
This calculator does not cover structural wall changes, major layout relocation, new windows or doors, asbestos removal, permits, design fees or major electrical panel upgrades. If your project involves any of these, price them separately with a specialist. For a full multi-room project, the Home Renovation Cost Estimator covers the complete budget across rooms and trades.
