How is data transfer cost calculated?

First the volume is converted to GB (1 GB = 1000 MB). The free allowance is subtracted, and the remaining billable GB is multiplied by the price per GB. For example, 500 GB with a 100 GB free tier at 0.09 per GB costs (500 − 100) × 0.09 = 36.00.

How accurate is the estimate?

It is accurate for a flat per-GB price, but many providers use tiered pricing, per-region rates and separate inbound/outbound charges. Use your provider's exact per-GB rate and free tier for the closest figure; the currency symbol is a label only and applies no exchange rate.

Is my usage data sent anywhere?

No. The calculator is privacy-first and runs entirely in your browser — the figures you enter never leave your device.

Estimate what your data transfer (egress) will cost on a cloud host or CDN. Providers bill outbound data per gigabyte and usually bundle a free monthly allowance, so the calculation is:

cost = (total GB − free GB) × price per GB

For example, 500 GB of egress with a 100 GB free tier at 0.09 per GB works out to (500 − 100) × 0.09 = 36.00. Volume is converted using decimal units (1 GB = 1000 MB), and the currency selector is a display label only — no exchange rate is applied. Everything is calculated locally in your browser — nothing is sent anywhere.
