Cost Per GB Processed Calculator

Work out cost per gb processed instantly with clear inputs, formula shown and shareable results.

About Cost Per GB Processed Calculator

Cost per gigabyte processed is the unit metric for data platforms, and tracking it separates growth from inefficiency. If volume grows 12 percent and cost grows 12 percent, efficiency is flat and the platform is scaling linearly — which is acceptable but means no economies of scale are being realised from batching, compression or better partitioning.

Formula

Unit cost

cost per GB = monthly cost / GB processed; cost at target = GB x target rate; linear projection = cost x (1 + volume growth)

Worked example

With the default values below, Cost Per GB Processed Calculator returns Cost per GB processed of 3.778. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Should the unit be raw or compressed bytes?

Pick one and be consistent. Raw bytes is a better business measure since it tracks what the business generates; compressed bytes better reflects what you pay to store.

Why should unit cost fall with scale?

Fixed platform overhead is amortised over more volume, and larger batches amortise per-job startup cost. If it does not fall, the pipeline is dominated by genuinely variable per-byte work.
