Pay for file invalidation
The first 1,000 invalidation paths that you submit per month are free; you pay for
each invalidation path over 1,000 in a month. An invalidation path can be for a
single file (such as /images/logo.jpg) or for multiple files (such as
/images/*). A path that includes the * wildcard counts as one
path even if it causes CloudFront to invalidate thousands of files.
The maximum of 1,000 free invalidation paths per month applies to the total number
of invalidation paths across all of the distributions that you create with one
AWS account. For example, if you use the AWS account john@example.com
to create three distributions, and you submit 600 invalidation paths for each
distribution in a given month (for a total of 1,800 invalidation paths),
AWS will charge you for the difference between the total invalidation paths and
the 1000 free limit. In this example, AWS would charge you for 800 invalidation
paths in that month.
The charge to submit an invalidation path is the same regardless of the number of
files you’re invalidating: a single file (/images/logo.jpg) or all of
the files that are associated with a distribution (/*). Because you're
charged per path in your invalidation request, even if you bundle multiple paths
into a single request, each path is still counted individually for billing purposes.

Tag invalidation paths count toward the same 1,000 free invalidation paths per
month allowance. For example, if you submit 500 path invalidations and 600 tag
invalidations in a month (for a total of 1,100 invalidation paths), you are charged
for 100 invalidation paths. A single tag invalidation item (for example,
#product:electronics) counts as one path regardless of how many cached
objects it invalidates — the same as a wildcard path invalidation (for example,
/*) counts as one path.
