What is a buy to let rent calculator?

A buy to let (BTL) rent calculator estimates how much rental income you need to cover your buy to let mortgage repayments, helping you plan the next stage of investments with confidence.

As well as calculating what rental income is required, it's also important to plan for other costs such as stamp duty and mortgage overpayments.

How to use our buy to let rental income calculator

Our BTL rental calculator is easy to use and you don't need to input any personal details. You'll just need to add:

  • The property value
  • Deposit amount

The deposit amount should be a minimum of 25% of the property's value. This is because most lenders offer a loan-to-value ratio of a maximum of 75% on buy to let mortgages. At a minimum, your rental income should also cover 125% of the mortgage interest payments.

Based on the information you enter, the calculator will provide an estimated rental income value. This is the minimum amount you should aim to charge per month to cover your BTL mortgage costs. For example, for a property with a value of £250,000 and a deposit of £100,000, you should aim for a minimum rental income of £750 per month.

If you already know your expected monthly rental income but want to find out how much you could borrow with a BTL mortgage, you can try our buy to let mortgage calculator.

Buy to let rent calculator FAQs

The BTL rental calculator can give you an estimate of the minimum rental income you need to be able to cover 125% of your buy to let mortgage interest repayments. It calculates this based on the property value and your deposit amount. It cannot provide an exact figure but it is useful as a rough guide, enabling you to make better-informed investment decisions.

The bigger the deposit you put down, the less you'll need to borrow as a percentage of the property's value. Your BTL mortgage repayments will therefore be lower if you put down a higher deposit.

Your rental income then needs to cover the cost of your repayments (typically at a rate of 125% of the mortgage interest payments), so the more you put down as a deposit, the lower the required rental income.

It's also important to be aware that most lenders require a minimum 25% deposit.

The amount you can borrow is based on a variety of factors including:

  • Your expected rental income
  • The value of the property
  • Your credit history
  • Your annual income
  • Your employment status
  • Any existing debts you have
  • Lender-specific criteria

These will be assessed by the lender when you apply for a BTL mortgage but, for a rough estimate of what you might be able to borrow, use our buy to let mortgage calculator.

Our rent value calculator doesn't require a credit check as it doesn’t need any personal details. It's a simple way of finding out what your expected required rental income might be based on the deposit amount and the property's value. You can use the calculator as many times as you need without it affecting your credit score.

Lenders will carry out more thorough checks and will conduct a credit check if you apply for a BTL mortgage.

Our rent calculator is designed to give an estimated amount so you can cover 125% of the BTL mortgage interest payments. The actual amount you might get from your rental income is likely to be influenced by factors such as the property, the location and the overall rental market. These are all things you should consider when thinking about adding to your property investment portfolio.
