Interest Only Loan Calculator

With an easy to create interest-only schedule

An interest-only loan is a type of loan in which the borrower only pays the interest on the loan during a specified period, usually for the first few years of the loan term. This means that the borrower is not paying down the principal amount of the loan, but only paying the interest charged on the principal.

Additional instructions for the interest-only loan calculator

  • Loan Amount: Enter the total amount of the loan you are taking out. This can be entered as a numerical value (e.g. 100000), with or without decimal places.
  • Payment Amount: Enter the amount of each payment you will make to pay off the loan. This can be entered as a numerical value (e.g. 2500), with or without decimal places. If you are unsure of the payment amount, you can enter 0 and the calculator will calculate this value based on other inputs.

Note: You must enter one of the two above values and leave one value as 0, and the calculator will calculate the unknown value based on the entered value.

  • Number of Payments: Enter the number of interest-only payments you will make.
  • Annual Interest Rate: Enter the annual interest rate that will be charged on the loan. This must be entered as a percentage (e.g. 5%)
  • Payment Frequency: Choose the frequency at which you will make payments. This can be monthly, weekly, bi-weekly, quarterly etc. Select the appropriate option from the drop-down list.
  • Compounding: Choose the frequency at which interest will be compounded on the loan. If you do not know this value, then set it to equal the payment frequency.

Potential benefits of an interest-only loan

One benefit of an interest-only loan is that the monthly payments can be lower during the interest-only period, making it easier for borrowers to manage their cash flow. This can be particularly attractive to borrowers who expect their income to increase significantly or who have irregular income streams.

Risks of an interest-only loan

However, one major risk of an interest-only loan is that the borrower will have to pay a much larger monthly payment once the interest-only period ends, and the borrower must start paying down the principal. This can cause financial strain and may even lead to default if the borrower cannot make the higher payments.

Another risk of such a loan is that the borrower may end up owing more money than they initially borrowed, as they have not been paying down the principal during the interest-only period.

Interest-only loans are typically used for investment properties or in situations where the borrower expects to sell the property or refinance the loan before the interest-only period ends. It is important for borrowers to carefully consider their financial situation and goals before choosing an interest-only loan, and to fully understand the terms and risks associated with this type of loan

      Can you provide me with your inputs so that I can try your calculation?

    I printed a loan summary. All the details are correct with the exception that I want to change the loan date to a date for years earlier rather than December 1, 2023. Please advise how I do this. And I also want to record the payment was made towards the end of the term
    please advise
