How does this calculator work?
A server draws power even when idle. Measure average wall consumption for a realistic ownership cost.
A practical what-if example
Compare up-front hardware, storage, electricity and avoided subscriptions over several years.
Important costs and limitations
Drive replacements, backups, networking, maintenance time and media access rights need separate consideration.
Which inputs make the biggest difference?
Start by adjusting server hardware, then storage and disks and average 24/7 power (w). These are editable assumptions rather than mandatory averages. Changing one slider at a time lets you see which inputs matter most. Use values from your own bills, estimates or accounts where available rather than treating the defaults as market benchmarks.
Compare a conservative and an ambitious scenario
First create a conservative estimate with your known numbers. Then increase storage and disks and check average 24/7 power (w) along with other relevant items (electricity price / kwh replaced subscriptions / month years to compare). This yields a more useful range than a single unexplained prediction. Save or note both results when planning next steps.
Using your estimate in the real world
This technology tool provides a transparent planning estimate. Calculations run in your browser without registration. It is designed for comparison and personal planning, not a binding quote or financial, legal or tax advice. Check local regulations and actual provider terms before committing.
Common mistakes to avoid
Do not mix up server hardware and storage and disks: the units and periods may differ. Watch out for annual versus monthly amounts, percentage assumptions and costs already included elsewhere. Enter each expense only once and verify the calculations shown in the results panel.
Why can your actual outcome differ?
Two similar situations may produce different outcomes due to average 24/7 power (w) or charges outside the model. Instead of making unsupported promises, the calculator displays editable assumptions. Prices, platform fees and local tax rules can change, so use the result as an initial estimate only.
Frequently asked questions
How much electricity does a server use running 24/7?
Multiply average watts by 24 hours and 365 days, divide by 1,000 and apply your electricity price. Idle power consumption matters for always-on hardware.
Does a Jellyfin server automatically replace streaming subscriptions?
Not necessarily. Count only subscriptions you would genuinely cancel, then include drives, backups, replacement hardware and maintenance time.
