What Is a Good Rental Yield? Gross vs Net, Explained

How to calculate gross and net rental yield, the costs that turn 6% into 4%, and how to judge whether a buy-to-let's yield is actually good.

The short answer

A gross rental yield of around 5–8% is often treated as healthy, but the number that really matters is the net yield — after costs, empty months and buying costs — which is commonly 1.5–3 points lower. Yield also has to be weighed against how much the property might grow in value: high-yield areas often grow more slowly.

Rental yield is the first number any landlord or investor looks at, and also the most quoted out of context. A listing that says “8% yield!” is almost always giving you the gross figure — rent divided by price — which ignores every cost of actually owning the place. Here's how to work out both, and how to judge what you see.

Gross vs net yield

  • Gross yield = yearly rent ÷ property price × 100. Quick, useful for comparing listings, and flattering.
  • Net yield = (rent you actually collect − running costs) ÷ (price + buying costs) × 100. Slower to work out, and the one that tells you whether the property pays.

Neither includes mortgage interest or income tax — yield measures the property, not your financing.

Worked example

A flat costs £250,000 and rents for £1,250 a month.

  1. 1
    Gross yield: £1,250 × 12 = £15,000 a year. £15,000 ÷ £250,000 = 6.0%.
  2. 2
    Allow for 5% vacancy (about two and a half weeks empty a year): £15,000 × 0.95 = £14,250 collected.
  3. 3
    Subtract running costs — letting agent, insurance, repairs, service charge — say £3,000: £11,250.
  4. 4
    Add buying costs to the price — stamp duty, legal fees, a few fixes — say £9,000: £259,000.
  5. 5
    Net yield: £11,250 ÷ £259,000 = 4.3%.

The advertised 6% became 4.3% before a single pound of mortgage interest. That gap is normal.

So what's a good yield?

There's no single answer, because yield is only half of the return. The other half is capital growth:

  • Expensive, popular cities often have low yields (3–5% gross) because prices are high relative to rents — investors accept that in the hope of stronger growth.
  • Cheaper towns can show 7–10% gross, but prices may grow slowly, tenants may be harder to find, and costs eat a bigger share of a smaller rent.
A useful sanity check: if the net yield is lower than the interest rate on your mortgage, the property costs you money every month unless rents rise. That can still work out with growth — but go in knowing it.

To see the return on your money once a mortgage is involved, combine the mortgage calculator with the ROI calculator.

Frequently asked questions

How do you calculate rental yield?

Gross yield is yearly rent ÷ property price × 100. Net yield is (rent collected − running costs) ÷ (price + buying costs) × 100.

What is a good rental yield in the UK?

Many investors look for 5–8% gross, but it varies widely by area. Net yields are usually 1.5–3 points lower.

Is a higher rental yield always better?

Not necessarily. Very high yields often come with slower price growth, higher vacancies or bigger maintenance bills.

Does rental yield include mortgage costs?

No. Yield measures the property itself. Mortgage interest and tax affect your personal return, not the yield.
