    • Hello Mr. Fazal,
      You can download the attached Excel file and use that as a template.
      All you need to do is input the number of years, periods per year, and balance. All the columns have their corresponding formula applied. As you provide the required information, Excel will automatically calculate the Loan Amortization Schedule for you.
      Last but not the least, you have to update the variable annual interest rate (AIR) manually. If you have any lump sum amount in your consideration don’t forget to update that too!
      Regards!

    Thank you very much for this excellent tutorial. I have been able to follow it without any problems at all. However, I need a variation to work with a different set of rules. If there is an example that covers this, please advise point me to the link.

    If not, perhaps you may be able to help me to solve the problem. This is a loan that ties the interest rate AIR, to the our country’s Reserve Bank Official Cash Rate (OCR). The OCR is increased in order to stop an over inflated economy.
    DETAILS;
    1. These are long term, fixed period loans. (Penalties are charged if lump sum payments are made to pay the loan off sooner than due date, except if the property is sold).
    2. Fixed installment for term of the loan.
    3. If the OCR goes up, the banks will follow.
    4. If the OCR goes down, the banks will follow, but never lower than the original AIR.
    5. The timing of the change does not match the timing of the due date of the installment, so split daily interest calculations have to be made to allow for the increase. Not a problem, just insert a row to enter the split for the new rate calculated for each set of days, both calculations based on the balance as at the date of the last principal payment.
    THE PROBLEM
    6. At the point when any increase in the OCR will cause the total amount owed to go up, that part of the excess interest increase has to be calculated, and is then added onto the fixed installment payment. This is done so the loan will repaid on the final period date, with the final installment. New loans are affected the most as there is no cushion from any earlier OCR decreases that may exist on a loan that has been in place for 4 or 5 years.

    I can do the calculation manually after the event, but I need to be able to have the changes calculated automatically as projections for the future based on political information ahead of time for budgeting purposes.

    Any help gratefully received.
    Thanks.

    Is it a legal practice to transform say, what started off as a fixed rate loan into a variable rate loan, somewhere down the life of a loan because of a sudden happening recession?

    • Hello RICHARD MUTALE BWALYA,

      Thank you for your question. Changing a fixed-rate loan to a variable rate depends on the terms and conditions of the loan agreement, in addition to the applicable laws and regulations in the jurisdiction where the loan was made.

      So, we believe it is best that you contact a financial advisor who can suggest the proper course of action based on your agreement.

  4. Hello
    I’ve downloaded this template, it’s great. I’m wondering how I can add in more interest rates. 10 rates are provided for, but I guess I need about 20 (ECB had 10 increases and now starting to decrease thankfully). I see on your tips it says to add them in manually, I assume I’m missing something totally obvious, but I cannot see how to do it.
    Any feedback, greatly appreciated.
    Thank you!

    • Hello Aisling,

      Thanks for your appreciation. To add more interests you’ll need to extend the interest rate list manually and adjust the formulas to include the new entries.
      Here’s how to do it:

      1. Add the additional 10 interest rates (or however many you need) in the interest rate table.

      2. Modify any formulas that reference the original range to accommodate the extended list.

      If you’re facing difficulties, ensure all formulas reflect the new range.

      Regards
