Cloud egress calculator

Enter what you send to the internet each month and what you would move out if you left. You get the monthly egress cost and the one-time exit cost at each provider's list prices, every price with its source and the day it was read.

Outbound only, in decimal TB (1 TB = 1,000 GB). The bandwidth calculator works it out from page views, downloads and API calls.
Everything you would copy out when leaving: object storage, databases, backups.
Only DigitalOcean's price list counts it: each Droplet adds its plan's allowance to a shared pool.

Cost by provider

Egress at list prices for 5 TB a month and a one-time exit of 50 TB. Providers are listed in a fixed order, not ranked.

                    months

                    Tiers reset every month, so a move spread over several months is priced at lower tiers more than once. One month is the simplest plan: the whole data set leaves in a single billing month.

                  What it does

                  It prices data sent from a cloud server to the internet at four providers' public list prices: what it costs every month, and what a one-time move of your data set out of the provider adds on top. Use it to compare egress before you choose a provider, or to put a number on leaving one.

                  How it works

                  1. Each provider's price list has a free allowance a month and price tiers per GB or GiB. Your monthly transfer is converted exactly to that unit (1 TB = 1,000 GB = 931.32 GiB), the allowance is taken off first, and each unit is priced by the tier it falls in.
                  2. Tier bounds are counted the way the provider states them: AWS and Azure count from the end of the free allowance, Google Cloud from the first GiB sent. DigitalOcean gives an allowance for each Droplet, so the number of servers matters there only.
                  3. One-time exit: the data set is added to the monthly traffic, spread over the months under Assumptions (one by default). The exit cost is what those months cost more than your usual months, so it is priced at the tiers your regular traffic leaves.
                  4. Past a provider's last published tier there is no list price, so the table says to ask the provider instead of guessing one.
                  5. Exit programmes are linked, not applied: each provider decides on them case by case.

                  The price lists

                  Every tier of every price list the calculator uses, as the provider states it, with the free allowance counted first.

                  Example

                  5 TB sent to the internet a month, a 50 TB data set moved out in one month, one server, at the shipped price lists:

                  5 TB a month · 50 TB exit · 1 server

                  Amazon Web Services: Every month
                  $441/month
                  Amazon Web Services: One-time exit
                  $4,221.2
                  Microsoft Azure: Every month
                  $426.3/month
                  Microsoft Azure: One-time exit
                  $4,106.7
                  Google Cloud: Every month
                  $378.81/month
                  Google Cloud: One-time exit
                  $3,138.47
                  DigitalOcean: Every month
                  $36.57/month
                  DigitalOcean: One-time exit
                  $465.66

                  Limits

                  • List prices for one region and network option of each provider, in USD, before tax, commitments, private pricing or credits. Other regions and Google Cloud's Premium Tier cost differently.
                  • Internet egress only: traffic between zones, regions or to a CDN, NAT gateway and load balancer charges are not included.
                  • The exit policies are summaries. Their terms (what qualifies, notice periods, what happens to your account) are only on the providers' pages, and this is not legal advice.
                  • A price older than 90 days carries the Stale mark until it is read again from its source.
