A technology consultant is analyzing data migration costs for a company moving 450 terabytes to a cloud platform. The provider charges $0.23 per gigabyte for transfer and $0.03 per gigabyte per month for storage. What is the total cost in dollars for the first year of storage after migration?

As more U.S. businesses transition to cloud infrastructure, data migration has become a critical decision—balancing speed, cost, and long-term efficiency. With 450 terabytes of data on the move, understanding the financial impact—especially storage expenses—helps consultants and decision-makers plan beyond the initial shift.

Calculating the true cost of moving data involves separating two key expenses: data transfer and ongoing storage. The transfer fee represents a one-time upfront cost for moving large volumes, while the monthly storage charge reflects predictable, recurring expenses tied directly to the amount of data retained and accessed.

Understanding the Context

Understanding Transfer vs. Storage Costs
Transferring 450 terabytes equals 450,000 gigabytes. At $0.23 per gigabyte, the total transfer cost reaches approximately $103,500. This is a strong initial investment, especially for mid-sized enterprises, but it’s a one-time event. Monthly storage charges, meanwhile, compound over time. At $0.03 per gigabyte, storing 450,000 GB costs $13.50 per month—equivalent to $162 per year. These recurring fees are often overlooked but make up the majority of annual storage expenses.

Total First-Year Storage Cost Breakdown
Over 12 months, storage expenses total $162 (12 × $0.03 × 450,000). Adding the one-time transfer fee gives a complete picture: $103,500 + $162 = $103,662. Though the transfer cost dominates upfront, storage adds predictable overhead—critical for budgeting across multi-year cloud strategies.
