Cloud Data Transfer Cost Calculator
Cost egress at your own price per GB, less any allowance you hold.
What this calculator does
Billable volume multiplied by the user's own per-GB price. No allowance is assumed; the user states the one they hold.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Price per GB transferred
- — Take this from your own bill or the provider's price page. No provider price is built in..
- Data transferred
- — number value.
- Free allowance (optional)
- — Optional component. Leave at 0 to exclude it from the result. Volume your agreement gives you at no charge..
- Price as of (optional)
- — The date you took these prices. It is shown with the result so the figure is never read as a current vendor price..
- Price source (optional)
- — Where the prices came from. Shown with the result..
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
Transfer cost = (GB transferred − Free allowance) × Price per GB
Worked example
2,500 GB out at $0.09 per GB
Any free allowance you actually have is deducted; none is assumed.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
Results depend entirely on the figures you enter and are rounded for display. They are for general information and education, not professional advice.

Common questions
Formula, source and verification
Billable volume, after any allowance the user actually holds, multiplied by the user's own per-GB price.
The question it answers: What will this compute, storage, transfer, function, container, cluster or database cost us for the period, at our own rates?
The formula
Transfer cost = (GB transferred − Free allowance) × Price per GB
- G — Data transferred
- (GB). Volume moved in the period.
- F — Free allowance
- (GB). Optional. Volume the agreement gives at no charge.
- r — Price per GB
- (currency). From the user's own bill or price page.
Units: Currency; gigabytes.
What kind of calculation this is
Business input model. The answer depends on business figures only you can supply, such as your own costs, rates or volumes. No market or benchmark values are assumed for you.
Method
Billable volume multiplied by the user's own per-GB price. No allowance is assumed; the user states the one they hold.
Assumptions built into the result
- Mathematical: Every price is the one the user entered, in the currency they chose; no exchange rate is applied.
- Mathematical: Usage and prices cover the same period.
Figures this calculator will never guess for you
- No provider price, instance rate, storage rate or transfer rate is built in.
- No typical discount, saving or industry average is suggested.
- No free tier is assumed.
Limitations
- The result is only as current as the prices entered; a price taken months ago is not a current vendor price.
- Arithmetic over the figures entered — it cannot tell whether the usage or the rate card behind them is right.
- One flat rate is applied; tiered transfer pricing must be entered tier by tier.
