Formula Used
The calculator uses the following formula to estimate your monthly cost:
Monthly Cost = (Base Plan Cost + Data Overage Cost + Talk Time Overage Cost) × Discount Factor
Where:
- Base Plan Cost - The cost of your selected data and talk time plan
- Data Overage Cost - Additional cost for exceeding your data allowance (if applicable)
- Talk Time Overage Cost - Additional cost for exceeding your talk time allowance (if applicable)
- Discount Factor - The discount applied based on your contract term
The calculator uses AT&T's current MST 3.0 rate structure for these calculations.
Worked Example
Let's calculate the monthly cost for a user with the following details:
- Data Usage: 20 GB/month
- Talk Time: 500 minutes/month
- Device Type: Smartphone
- Contract Term: 24 months
Based on AT&T's MST 3.0 rate plan:
- Base Plan Cost: $50/month (includes 15 GB data and 400 minutes talk time)
- Data Overage Cost: (20 GB - 15 GB) × $10/GB = $50
- Talk Time Overage Cost: (500 minutes - 400 minutes) × $0.10/minute = $10
- Discount Factor: 24-month contract provides a 10% discount
Total Monthly Cost = ($50 + $50 + $10) × 0.90 = $94.50
This example shows that with 20 GB of data usage and 500 minutes of talk time, the estimated monthly cost would be $94.50 after a 10% discount for the 24-month contract.
