Local AI vs Cloud Break-Even Calculator

Use this page when the decision is not which GPU fits a model, but whether buying local hardware beats paying every month for cloud or subscription AI.

Local vs Cloud Break-Even Calculator

Compare a one-time hardware purchase against an ongoing cloud AI subscription, including the electricity to run your rig.

Defaults compare a typical $20/month plan against an $800 used-GPU rig. Replace every value with your own.

Local power / month $4
Savings / month $16
Break-even 51.0 months
3-year: local vs cloud $956 vs $720

This is a planning estimate. It counts hardware as a one-time cost plus electricity to run it, and treats cloud as a flat monthly fee. It does not model resale value, hardware that you would have bought anyway, or heavy API usage that costs far more than a flat plan. Power uses board TDP as a ceiling — real inference draw is usually lower.

Why This Page Exists

Unique value

This page is unique because it models the ownership decision rather than raw electricity cost or model memory fit.
