UK Rental Yield Calculator

Yield is a key signal, but not a decision by itself. CapitaLens combines yield with NOI, debt exposure, and operating costs so the underwriting conclusion reflects full deal economics.

Core calculations

Gross yield
Net yield
Annual NOI
Financing impact
Operating cost structure

Two deals can share similar yield but carry very different downside risk. Underwriting should always include stress outcomes and financing sensitivity alongside yield.

Gross yield vs net yield

Gross yield uses rent and purchase price only
Net yield reflects operating costs and vacancy assumptions
NOI captures recurring income quality after non-financing costs
Debt structure can materially change monthly free cashflow

Why cashflow matters more than headline yield

High headline yield can still produce weak cashflow once mortgage costs, voids, fees, and maintenance are fully reflected. Sustainable monthly cashflow is often a stronger indicator of underwriting quality.

How underwriting improves yield interpretation

CapitaLens connects yield metrics to financing assumptions, operating cost pressure, and stress outcomes so investors can distinguish between attractive optics and durable returns.
