Compare annual cloud storage + egress bills: same raw terabytes, packed with zstd-3 vs X-Lex™. The dollar gap is the saving. Pick a measured data mix — JSON composition changes the ratio.

Cloud footprint (billable compressed TB)
Same raw TB above — different packed size on disk / on the wire:
Raw (uncompressed input)—zstd-3 stored / transferred—X-Lex™ stored / transferred—
How to read the table:
Add Storage + Egress in each column → Total annual spend.
The green number below is not the X-Lex column added together — it is
zstd total minus X-Lex total.
Cost Categoryzstd-3X-Lex™
Static Storage Cost:$0$0
Network Egress Cost:$0$0
Total Annual Spend:$0$0
Annual savings vs zstd-3$0 / year*Estimate only — ratio is from the selected sample, not a guarantee for your JSON.
Notice:
Compression ratio is not constant. Dollar savings are vs zstd-3, not vs raw. On observations 32 MiB both codecs are already very dense, so the USD gap can look modest even though X-Lex™ is ~3.1× smaller than zstd. Mixed execution_log (~20× vs raw) is the default ROI sample.
