Rental yield is the amount of money you make on an investment property by measuring the gap between your overall costs and the income you receive from renting it out. 

Here’s how to calculate gross rental yield:

1. Sum up your total annual rent that you would charge a tenant

2. Divide your annual rent by the value of the property

3. Multiply that figure by 100 to get the percentage of your gross rental yield

To calculate net rental yield, follow these steps:

1. Add up all the fees and expenses of owning the property

2. Sum up the annual rent you will receive from the property 

3. subtract the total expenses from the annual rent 

4. Divide it by the value of the property

5. Multiply by 100
