In short: Equivalent yield is a single rate that values both the current rent and the expected future rent (the estimated rental value, or ERV) once the lease reverts or is reviewed. It sits between the initial yield (current rent ÷ price) and the reversionary yield (ERV ÷ price). Valuers use it to compare properties where the passing rent is above or below market. Our calculator works it out using a simple term-and-reversion model. Fraser Bond helps investors value, buy, let and sell commercial property.

Key commercial yield measures

Reversionary yield–
Equivalent yield–

A simplified annual-in-arrears term and reversion model, before purchase costs. Valuers may use quarterly in advance and include costs.

Reversionary

Passing rent below ERV: the yield rises as rent catches up.

Over-rented

Passing rent above ERV: income may fall at the next event.

Rack-rented

Passing rent equals ERV: all three yields are similar.

Costs

Net yields deduct purchaser's costs.
