Compare two premises using rent, extra charges, incentives and opening costs.
Compare the full cost.
Figures update as you type.
Premises A
Rates, service charges, insurance. Count each once.
3% yearly · 0 rent-free months · £14,000 setup · £6,750 deposit
Premises B

2% yearly · 2 rent-free months · £9,000 setup · £7,500 deposit
Replace all example figures with your quotes. This compares your assumptions, not market rents or legal lease terms. Use one currency and the same tax basis for both premises. Additional charges stay flat; rent increases annually. No currency conversion is performed.
How the comparison works: total cost = scheduled rent + recurring charges + setup costs. Average monthly cost = total ÷ lease months. Refundable deposits are excluded from total cost. Rent-free months waive base rent at the start; annual increases begin in month 13.
Useful to know
A few common questions.
Understand the result before making your next move.
What costs does this commercial lease calculator include?
It adds the base rent, additional monthly premises charges and non-refundable setup costs across your chosen term. Annual rent increases apply at the start of each new lease year. You can enter rates or property taxes, service charges and insurance in the additional costs field. Enter each charge once.
How are rent-free months and deposits treated?
Rent-free months come at the beginning of the term and waive base rent only. Additional charges still apply. Refundable deposits appear in upfront cash, but are excluded from the total cost. Setup costs are paid at the beginning and are included in the total.
Does it include VAT, tax relief or rent reviews?
It does not calculate taxes or reliefs. Use the same tax basis for both premises and include any non-recoverable tax in your own inputs. Percentage rent, break clauses, market rent reviews and finance costs are not modelled. Use the calculator to compare assumptions, then verify your actual lease terms.
Does the cheaper lease mean the better location?
No. The result compares the costs you enter. It does not forecast sales or judge customer demand, competition, condition or access. A more expensive property may suit your business better.
