Methodology
2026 kitchen cost-range model & assumptions
Base planning range
kitchen floor area × editable low/high benchmark rate × local market factor
The rates are visible inputs. Replace them with credible local or project-specific evidence when you have it.
Known add-ons
base range + entered layout / trade / permit add-ons
Use this only for costs not already represented by the selected benchmark or written contractor scope.
Contingency reserve
planning subtotal × contingency %
Keep uncertainty separate from expected cost so scope changes remain auditable.
Budget target range
planning subtotal + contingency reserve
The result is an early planning range, not a contractor bid, appraisal or promise of local pricing.
