How to Calculate Interest Rate Per Day

Formula for Daily Interest Rate

Daily Interest Rate = Annual Interest Rate/365

Steps for Calculation

  1. Determine the Annual Interest Rate: This is usually given by your financial institution.
  2. Divide by 365: This will give you the daily interest rate as a percentage (%)

Example Calculation

Suppose you have a savings account with an annual interest rate of 5%, and your principal amount is $10,000. Using the calculator, here’s the daily interest rate and amount:

  1. Annual Interest Rate: 5% or 0.05
  2. Interest Rate Per Day: 0.0137%
  3. Interest per day: $1.37

So, the daily interest accrued on your savings account would be $1.37.
