Why it matters

Request costs can become meaningful in high-throughput object storage workloads even when raw storage cost is modest.

When to use

  • Forecasting storage API cost
  • Comparing heavy-read and heavy-write workloads
  • Checking whether caching could materially reduce request spend

Inputs & Outputs

Inputs

  • GET and PUT requests should be counted in total request volume for the billing period.
  • Rates should be entered per 1,000 requests if that matches the provider quote.

Outputs

  • Request cost shows the estimated bill for the request mix entered.
  • Read vs. write breakdown helps explain what is driving the total.

Request billing method

Convert request counts into billable thousands, multiply by the corresponding GET and PUT rates, and sum the results.

Total request cost = (GETs / 1000 x GET rate) + (PUTs / 1000 x PUT rate)

Worked example

1

Static asset workload

A workload serves 48 million GETs and 3.5 million PUTs, with rates of 0.0004 and 0.005 per 1,000 requests.

Inputs

  • GETs: 48,000,000
  • PUTs: 3,500,000
  • GET rate: 0.0004
  • PUT rate: 0.005

Steps

  • Convert requests into billable thousands
  • Multiply by each rate and sum the results

Result

  • The calculator estimates the total request component of the storage bill.

Edge cases & caveats

  • Additional request classes may exist depending on the provider.
  • This tool does not include transfer or storage charges.

Frequently Asked Questions

Why do PUT requests cost more than GET requests?

Many providers price write operations higher because they involve more backend work than read operations.

Should I include failed requests?

Use the billing definition from your provider. Some platforms bill all requests that reach the service.
