Break-even

18,394GPU-hours

About 17.7 years at 20 h/week.

Use the card for fewer hours than that and renting is cheaper; use it more and buying wins. At your usage that is $1,997 a year of rental spend (after the electricity you would pay to run your own card), against a one-time $35,316.

Starting usage, electricity and wattage values are editable examples, not measured consumption.

Formula: break-even hours = hardware price ÷ (rental $/hr − electricity $/hr), where electricity $/hr = watts ÷ 1000 × $/kWh. Resale value, cooling and your time are not included: the calculation covers purchase price, GPU electricity and rental compute only.

The rental input covers GPU compute. Check egress, storage and stopped-instance charges before treating this break-even as an all-in cloud budget.
