Formulas for Daily Interest
Simple Daily Interest
Daily Interest = (Principal × Annual Interest Rate) / 365
Total Amount = Principal + (Daily Interest × Number of Days)
Compound Daily Interest
Total Amount = Principal × (1 + (Annual Interest Rate / 365))^Number of Days
Daily Interest = Total Amount – Principal
Where:
Principal: The initial loan or investment amount (e.g., $10,000).
Annual Interest Rate: The yearly interest rate as a decimal (e.g., 5% = 0.05).
Number of Days: The time period for interest calculation.
For example, for a $10,000 loan at 5% annual interest over 30 days:
Simple Daily Interest = ($10,000 × 0.05) / 365 ≈ $1.37/day
Total Interest = $1.37 × 30 ≈ $41.10
Total Amount = $10,000 + $41.10 = $10,041.10

Example Calculation
Problem: Calculate the daily simple interest for a $5,000 loan at a 6% annual interest rate over 60 days.
Step-by-Step:
Formula: Daily Interest = (Principal × Annual Interest Rate) / 365
Input Values:
- Principal = $5,000
- Annual Interest Rate = 6% = 0.06
- Days = 60
Calculate:
- Daily Interest = ($5,000 × 0.06) / 365 ≈ $0.8219/day
- Total Interest = $0.8219 × 60 ≈ $49.32
- Total Amount = $5,000 + $49.32 = $5,049.32
Result: The daily interest is approximately $0.82, and the total amount after 60 days is $5,049.32.
