Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Apply the free allowance to transfer only, then add the two entered charge components.
Cost=max(0,traffic−free)×GB price+requests/1e6×request price+fixed charge
Worked example
1000 GB, 100 GB free and 0.08/GB cost 72 in transfer, before request/fixed charges.
Assumptions and input details
User-entered prices, one currency and one billing interval. No vendor rate catalogue, regional routing, tax, currency conversion or tiered contract terms. All requests are billable at the entered rate.
Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Estimate origin request and response traffic from separate request-hit and byte-hit ratios.
Estimate media file size from duration and average audio/video bitrates, or solve the video bitrate available under a file-size limit.
Find transfer time, required nominal speed or data size. Distinguish bits, bytes, decimal and binary units and include an explicit effective-throughput percentage.
