Will It Local? / Break-even matrix
Every rig against every cloud
One workload, one electricity rate, one amortization horizon — and a verdict for every rig paired with every cloud. Cloud Spread does one rig against all clouds; the Rig Finder does all rigs against one cloud. This is the whole board. Read across a row: the verdict flips as the cloud you'd rent gets cheaper. That flip is the entire point of the site.
Now showing: Coding assistant usage (~15M tokens/mo), the U.S. average electricity ($0.1883/kWh), 3-year amortization. Of 36 pairings: 17 OWN, 9 HYBRID, 10 RENT. Same rigs, same electricity — the cloud you'd otherwise pay for is what moves most of these.

Each cell shows the verdict and its break-even month; the rig row shows build cost and local cost of ownership. OWN = a fast payoff, early in the rig's life. HYBRID = pays off only in the back stretch of that life. RENT = never before the hardware is due for replacement. Click any cell for the full breakdown. Every number is the same engine the calculator runs — the matrix can't say something the calculator wouldn't.
