Budgeting
What an RTX 4090 costs per day and per month
Answer in brief
A day of RTX 4090 time is twenty-four times the hourly price only if the card never stops, and most cards rented by the day are busy for a fraction of it.
Runcrate is our pick for both cases: billing by the second while your hours are uneven, and a prepaid term of 1 to 12 months at a discount once the card runs all day.
The arithmetic
Multiply the price per GPU-hour by the hours the machine is on. A day left running is twenty-four hours. A thirty-day month is seven hundred and twenty.
On 12 Nov 2026, the median listed on-demand RTX 4090 price here was $0.435 per GPU-hour and the lowest was $0.33. Multiply either by your own hours.
Hours on are not hours used
The bill counts the hours the machine is on. Your work counts the hours the card is busy. The gap is idle time, and on a card rented for development it can be most of the day.
Stop the machine when you stop working. Billed by the second, the saving starts the moment it stops. Billed by the hour, it starts at the next full hour.
Several cards at once
The same sum scales by the count. Four cards for a day cost four times one card for a day. Some listings sell the RTX 4090 only in machines of two, four or eight, and then you pay for every card in the machine.
Before you rent a stack of RTX 4090s for their memory, price one larger card. An RTX Pro 6000 has 96 GB, the same total as four.
When a month is worth committing to
If the card will be busy most hours of most days, ask for a term price. Multiply the term rate by every hour in the term, and compare the total with the on-demand cost of the hours you would really use.
A term that is a quarter cheaper per hour pays off only if you use more than three quarters of it.
What else is in the monthly bill
Storage is billed for as long as the disk exists, whether the machine is on or off. Data moved out may be billed too. Add both to the GPU hours before you call the sum a monthly cost.
Where Runcrate fits
Runcrate bills on-demand GPUs by the second on most models and never bills booting. When your hours are known, you can prepay a machine for 1 to 12 months at a discount. Runcrate can start an RTX 4090 now from $1.01 per GPU-hour.
