# Occupancy Cost Estimator

## TL;DR

- Model fully-loaded annual occupancy cost.
- Includes base rent, OpEx/[service charge](/glossary/service-charge), [business rates](/glossary/business-rates)/property taxes, and amortized [fit-out](/topics/fit-out-capex)">fit-out.
- Output is per-seat and per-sqft so you can benchmark across cities.

## Methodology

Rent + OpEx + property taxes + (fit-out capex / amortization period). Currency-converted to USD for cross-market comparison.

## How to use it

- **Pick a city** — Select a Tier 1 market — local benchmarks for rent, OPEX, and taxes load automatically.
- **Enter headcount and area** — Provide expected headcount and target square footage or square meters.
- **Set lease structure** — Choose lease term, rent escalators, free-rent months, and fit-out amortization period.
- **Review the stack** — See annual and per-seat occupancy cost broken out by line item with currency conversion.

## Frequently asked questions

****Are taxes included?****
: Yes — UK business rates, US RE taxes, and equivalents are modeled per market.

****How is fit-out amortized?****
: Default is straight-line over the lease term; configurable from 5–15 years.
