Formula Used in the Calculator
This tool uses a simplified financial model based on monthly penalty and interest calculations.
Step 1: Convert Days Into Months
Months Late=30Days Late
This converts the delay into a monthly basis for easier penalty calculation.
Step 2: Calculate Penalty
Penalty=Amount×(100Penalty Rate)×Months Late
Step 3: Calculate Interest
Interest=Amount×(100Interest Rate)×Months Late
Step 4: Total Payable Amount
Total=Original Amount+Penalty+Interest
Example Calculation
Let’s understand this with a real-life scenario.
Example:
- Original bill amount = $2,000
- Days late = 60 days
- Penalty rate = 1.5% per month
- Interest rate = 0.5% per month
Step 1: Convert days into months
60 ÷ 30 = 2 months late
Step 2: Calculate penalty
Penalty = 2000 × (1.5 / 100) × 2
Penalty = 2000 × 0.015 × 2
Penalty = $60
Step 3: Calculate interest
Interest = 2000 × (0.5 / 100) × 2
Interest = 2000 × 0.005 × 2
Interest = $20
Step 4: Total payable
Total = 2000 + 60 + 20
Total = $2,080
