What is Daily Compound Interest?

Daily compound interest is a method of calculating interest that adds interest to the principal balance each day. This results in interest on interest, causing the investment to grow at a faster rate compared to less frequent compounding periods (like monthly or annually).

Key Benefits of Daily Compounding

  1. Faster Growth: Compounding daily increases the frequency of interest calculation, accelerating growth over time.
  2. Higher Returns Over Time: Even small contributions grow faster with daily compounding compared to annual or monthly.
  3. Ideal for Short-Term Goals: Daily compounding suits high-interest savings accounts or investments with short to medium-term goals.

 The Formula for Daily Compound Interest

The daily compound interest formula is:

– P = the principal amount (the initial sum of money).

– r = annual interest rate (decimal).

– n = the number of times interest is compounded per year (365 for daily).

– t = the time the money is invested for in years.

Example Calculation

Suppose you invest $1,000 at a 5% annual interest rate with daily compounding over three years:
