Calculate price per GB from a total price and storage capacity, or find the total cost or how much storage a budget buys, in GB, TB or GiB.

1 GB = 1,000,000,000 bytes; 1 GiB = 1,073,741,824 bytes.

Price per Gigabyte Formula

PPG = TP / TGB

Formula source:  5.11: Ratios and Rate (Part 2) – Prealgebra 1e (OpenStax)

Variables:

  • PPG is the Price per Gigabyte ($/GB)
  • TP is the total price ($)
  • TGB is the total data (GB)

Divide total price by decimal capacity in GB (1 GB = 1,000,000,000 bytes). For a per-GiB result use 1 GiB = 1,073,741,824 bytes, and compare quotes for the same billing period and included services.

How to Calculate Price per Gigabyte?

The following steps outline how to calculate the Price per Gigabyte.

  1. First, determine the total price ($). 
  2. Next, determine the total data (GB). 
  3. Next, gather the formula from above = PPG = TP / TGB.
  4. Finally, calculate the Price per Gigabyte.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total price ($) = 67

total data (GB) = 2

FAQ

What does Price per Gigabyte mean?

Price per Gigabyte refers to the cost of storing or transmitting one gigabyte of data. It’s a way to measure the cost-effectiveness of data storage or data transfer services, allowing consumers to compare prices.

Why is calculating Price per Gigabyte important?

Price per gigabyte helps compare unit costs, but it does not by itself establish best value. Compare the same capacity definition and billing period, and include relevant taxes, delivery, egress, retrieval, power and other ownership charges.

Can the Price per Gigabyte formula be used for any data size?

Yes. Convert capacity to the selected GB or GiB basis before applying the unit price. Linear scaling assumes the same quoted rate applies; tiers, minimum fees and other charges require separate treatment.

How does data size affect the Price per Gigabyte?

The total data size significantly affects the Price per Gigabyte. Generally, larger data sizes can reduce the Price per Gigabyte due to economies of scale, making higher data plans or larger storage devices more cost-effective per gigabyte.
