Portfolio ROI Calculator

01 — Portfolio Scale

Number of sites i The total count of distinct occupied locations — offices, warehouses, retail units, or any other leased premises. Each site typically has its own lease agreement.

Total sq ft i The total net internal area (NIA) or net lettable area across all sites. Use the figure on your leases if available. A rough estimate still produces a useful directional output.

02 — Occupancy Cost

Average rent per sq ft (£) i The headline passing rent per square foot, per annum — as stated in your leases, excluding rates, service charge, and other occupancy costs. This is Canvus's primary savings lever.

Unknown? We'll benchmark against comparable market evidence in discovery →

Total property cost per sq ft (£) i The all-in cost to occupy — rent plus business rates, service charge, insurance, and FM/facilities management.

Typically 1.6–2.2× headline rent in UK regional offices; up to 2.5–3× in prime Central London. Leave blank if unknown. Optional

Typically 1.6–2.2× headline rent in UK regional offices. Leave blank if unknown.

03 — Space Performance

Average occupancy (%) i Occupancy is the proportion of desks or seats physically in use — typically measured as a headcount-to-desk ratio or from badge/access data.

Different from utilisation, which measures how effectively all space types are used across time. Canvus will refine this during discovery.

Unsure? Estimate the % of desks typically filled on a busy day. We'll model this properly in discovery →

04 — Mandate Focus

Primary objective i Your primary mandate determines the value multiplier and savings levers applied in the model. Choose the option closest to your current board-level priority.
