What this calculator estimates

Estimate WALE/WALT using up to four tenant rent-and-term inputs. It combines the inputs below to produce Weighted average lease expiry. Every assumption remains editable so the estimate can reflect the property, financing and location being evaluated.

Worked example

Using the displayed sample assumptions, the calculator produces 4.54 years. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.

Inputs and assumptions

• Tenant 1 annual rent — sample input: 150000 currency units
• Tenant 1 remaining years — sample input: 3 years
• Tenant 2 annual rent — sample input: 100000 currency units
• Tenant 2 remaining years — sample input: 5 years
• Tenant 3 annual rent — optional — sample input: 75000 currency units
• Tenant 3 remaining years — sample input: 7 years
• Tenant 4 annual rent — optional — sample input: 0 currency units
• Tenant 4 remaining years — sample input: 0 years

How to interpret the result

Reconcile the result with leases, invoices and property records. Compare a conservative case with an expected case and keep a record of the assumptions used.

Common mistake to avoid

Do not mix physical occupancy with economic occupancy. Local definitions, taxes, lending practices and measurement requirements can materially change the result.
