GPU Break-Even Calculator: Rent vs Buy a DGX Spark or Turnkey System

Enter your hours, a current rental rate and your hardware price to compare renting a cloud GPU, buying bare hardware and a turnkey system over time. Runs in your browser; nothing is sent or stored.

Read this first: every default except the two dated prices is a placeholder, not a quote. Replace the rental rate with a current offer you actually found, and your own hours and costs. A rented GPU and a DGX Spark are not the same machine, so this compares cost, not speed.

Buying bare hardwareHardware price ($)Default: NVIDIA Marketplace DGX Spark 128 GB, last readable on 2026-10-06 (out of stock).One-time setup cost ($)Your engineering time to install, configure and secure it.Average power draw while in use (watts)Your estimate. NVIDIA lists a 140 W chip TDP and a 240 W power supply for DGX Spark.Electricity price ($ per kWh)Placeholder; use your local rate.Resale value at the end (% of price)Default 0 to stay conservative.

Turnkey system (optional comparison)Turnkey price ($)Default: Aradia's listed turnkey DGX Spark, read 2026-10-23 (hardware included).Monthly support plan ($ per month)Aradia lists an optional $1,500 per month Spark plan; default 0 means not taken.

Results

Lowest total cost at these inputs: renting.

Option	Ongoing cost per month	Total over horizon	Break-even versus renting
Rent a cloud GPU	$80	$2,880	Baseline
Buy bare hardware	$1	$6,993	About 88 months, beyond your 36-month horizon.
Buy turnkey system	$1	$15,168	About 192 months, beyond your 36-month horizon.

How it is calculated

Rent per month = hours × hourly rate + other rental costs.
Bare hardware total = price + setup cost + power cost × months − resale value. Power cost = watts ÷ 1,000 × hours × electricity price, assuming the machine draws power only while in use.
Turnkey total = turnkey price + (power cost + monthly support plan) × months. No resale value is applied.
Break-even = upfront cost ÷ (monthly rent − monthly ownership running cost). If renting is never more expensive per month than running the hardware, break-even shows as "never".

What this does not include

Speed. A rented GPU and a DGX Spark have different memory, bandwidth and software behavior; compare completed work, not just hourly cost.
Taxes, shipping, warranty, financing, cooling, space, upgrades and the cost of delays or outages.
Data constraints. If your data cannot leave your premises, renting may not be an option at any price.
Contract terms. Check cancellation and deposit terms before ordering a turnkey system; Aradia's page lists a cancellation fee of 40% of the Spark turnkey total before deployment.

Where the default numbers come from

The $6,950 hardware price is the last NVIDIA Marketplace reading we could take (2026-10-06, out of stock). The $15,125 turnkey price and the optional $1,500 monthly plan are from Aradia's pricing page, read on 2026-10-23. Everything else is a placeholder you should replace. Prices change; confirm current figures before you buy or rent.
