When your lease is about to expire, landlords often offer a renewal option. This can mean:

  • Extending the lease at the same rent,
  • Renewing with a rent increase, or
  • Adjusting other terms such as lease duration, maintenance fees, or services.

For tenants, whether residential, commercial, or business, knowing the cost impact of renewing a lease is crucial. That’s where the Lease Renewal Calculator helps.

This tool quickly estimates new rent payments, percentage increases, and total renewal costs, allowing you to compare options and budget effectively.

What is Lease Renewal?

A lease renewal is when both tenant and landlord agree to extend an existing lease contract beyond its original end date.

Types of renewals:

  1. Fixed Rent Renewal – Same payment continues.
  2. Percentage Increase Renewal – Rent increases by a set percentage.
  3. Indexed Renewal – Rent linked to CPI (inflation index).
  4. Negotiated Renewal – New rent agreed based on market value.
