Your billing plan is based on one of three credit types: Tests, Virtual User Hours or Server Hours
The simplest of the two. You will be charged for every test that you run, except for Debug tests that run for 10 Users and up to 5 minutes maximum.
E.g. If a test runs for 50 minutes on 2 engines, 1 Test credit will be billed.
Virtual User Hours:
Blazemeter calculates VUH as follows: Length of test in hours (rounded up to the next hour) * Max Users.
E.g. if a test runs for 90 minutes with 60 virtual users, 2 * 60 = 120 VUHs will be billed.
Note that a test's consumption of VUHs is based on the actual max concurrency and duration of the test. If you configured a one hour test ramping up to 20,000 Virtual Users but stopped it when it reached 10,000 Virtual Users, the test will only consume 10,000 VUHs. If the test was configured for 3 hours but you stopped it after 2 hours it will consume the max concurrency reached X 2 (Hours).
Your remaining test credits, as well as your credit type, can be checked by going to Settings > Accounts > Billing
This means that for every test you ran, we take the number of servers it ran on and multiply it by the number of hours the test ran. The number of hours is rounded up to the nearest whole hour. This is regardless of the number of VUs that are configured for the test.
e.g. if you run a test on 2 engines for a duration of 70 minutes, the number of server hours is 2 * 2 = 4.
