Understanding Your Rental Yield

Rental yield is one of the key indicators when assessing the performance or potential of a buy-to-let investment. It measures the annual rental income your property generates as a percentage of its purchase price or current market value.

Our calculator works out your gross rental yield, which is the simplest way to compare returns across different properties. It’s calculated before any deductions, giving an at-a-glance overview of your property’s income potential.

To calculate gross yield, your annual rent (monthly rent × 12) is divided by the property’s value, then multiplied by 100. For example, a property bought for £300,000 achieving £1,500 per month in rent would return a 6% gross yield.

While this is a useful benchmark, a true investment return depends on additional factors such as:

• Letting and management fees
• Maintenance and repairs
• Service charges and ground rent (if leasehold)
• Insurance and compliance costs
• Mortgage interest and tax allowances
• Periods when the property is vacant

After accounting for these, investors often look at net yield – the more realistic figure showing actual profit after expenses.

In Hertfordshire and North London, typical gross yields range from 4% to 7%, depending on property type, location, and tenant profile. Apartments in commuter areas may achieve higher yields, while family homes tend to offer stronger long-term capital growth.

If you’d like a detailed breakdown of net yields, cash-flow forecasts or capital growth projections, our Investment and Lettings teams can provide a personalised report based on your property and objectives.
