- Rate is the daily interest rate (0.18% or 0.0018 in decimal).

Worked Example
Let's calculate the interest earned on $1,000 over 30 days at 0.18% daily interest.
Principal: $1,000
Daily Rate: 0.18%
Time: 30 days
Calculation: $1,000 × 0.0018 × 30 = $5.40
Total Amount: $1,000 + $5.40 = $1,005.40
In this example, the interest earned is $5.40, and the total amount after 30 days is $1,005.40.
