What is Daily Compound Interest?

  • Daily compound interest calculates interest every day and adds it to the principal amount.
  • The next day, interest is calculated on the new total (including the previous day’s interest).
  • Daily compound interest often leads to higher earnings compared to monthly or annual compounding.

How to Calculate Daily Compound Interest?

  • Calculate the daily interest rate by dividing the annual interest rate by the number of days in a year.
  • Multiply the daily interest rate by the principal amount to find the interest earned for one day.

The formula for calculating daily compound interest is:

 Principal Amount × (1 + Daily Interest Rate)^(Number of Days) – Principal Amount

The result of this calculation will give you the total interest earned with daily compounding over the given time period.

Daily Compounding with Annual Interest Rate

  • Daily compounding with an annual interest rate means that the interest is calculated on a daily basis, but the interest rate itself is based on an annual rate.
  • To calculate the daily interest rate, divide the annual interest rate by the number of days in a year.
  • This approach allows for the continuous growth of your investment on a daily basis, maximising the potential returns.
