Why? Because it will play an important factor in determining how much your positive monthly cashflow will be.

But do not worry...

The main figures you will need to know to complete these and work out your monthly repayments will be your mortgage amount, the term of your mortgage and your interest rate.

Once you put these figures in you can receive two answers: how much your repayments will be if you are planning to pay 'interest only' or alternatively what your mortgage will be if you are doing a traditional repayment.

How to work out your properties monthly repayments

Now if you are interested in getting involved in the technical side of this equation, the following formula could help you to work it out by hand.

Take for example the following scenario.

You take out a £10,000 loan for over 5 years at an interest rate of 9% per year (or to make it easier 0.75% for 60 months). For this loan you will be facing a repayment of:

  • 10,000 x 0.0075 ÷ (1- (1 + 0.0075) -60) = £207.58 per month

With normal Building Society mortgages you may come across monthly repayments where your interest rate is compounding yearly. You can easily work this out too using the following formula.

For this example, let’s say you borrow from a Building Society £50,000 for a 25 year period that charges you 6% in interest per year (compounding annually):

  • 50,000 × (0.06 ÷ (1 + 0.06) -25) = £3,911.34 per year

    3,911.34 ÷ 12 = £325.94 per month

Making a choice

Now as an investor you will probably find yourself using the first equation as it is the most beneficial to you in terms of controlling your monthly repayments, but it is good to bear in mind the second as this could one day prove useful.
