> Recovering tenant-improvement spend through a rent uplift over the lease term.

## TL;DR

- Recovering tenant-improvement spend through a rent uplift over the lease term.
- Where a tenant-improvement allowance is exhausted, the landlord may agree to fund excess fit-out and amortise the cost into the rent at an agreed interest rate (typically 6–8%).

*Leasing · US, UK, EU, APAC*

## Short definition

Recovering tenant-improvement spend through a rent uplift over the lease term.

## Full definition

Where a tenant-improvement allowance is exhausted, the landlord may agree to fund excess [fit-out](/topics/fit-out-capex)">fit-out and amortise the cost into the rent at an agreed interest rate (typically 6–8%). Amortised TI is contractually rent — it must be paid even on early termination unless explicitly carved out.

## Example

USD 50/sf excess TI amortised at 7% over 10 years adds USD 7.10/sf/year.

## Why this matters for Class A leasing

TI amortisation is part of the leasing vocabulary that institutional [Class A](/glossary/class-a) occupiers, landlords, and advisers use across US, UK, EU, APAC markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
