Gaming & Tech Calculators
Calculate download times, PC power costs, storage, streaming data use and frame times.
12 calculators · instant answers
Featured calculators
A handpicked starting point for everyday calculations.
Internet & bandwidth
Estimate the wait and convert advertised connection speeds into transfer rates.
Download Time Calculator
Estimate file download time from its size and your connection speed. Compare the theoretical minimum with an adjustable real-world transfer estimate.
↗TransfersGame Download Time Calculator
Plan a game download using size presets or the download size shown in your launcher. The estimate covers the network transfer, not unpacking or installation.
↗TransfersUpload Time Calculator
Estimate how long a video, file or backup takes to upload. Use your upload speed and adjust the usable bandwidth for a realistic planning scenario.
↗TransfersMbps to MB/s Converter
Understand the difference between connection speed and transfer speed.
↗PC power & battery backup
Understand energy costs and the limits of hardware planning estimates.
PC Electricity Cost Calculator
Estimate your computer’s daily, monthly and annual electricity cost from average wall power, hours of use and your energy tariff. See both kWh and cost.
↗PowerGaming PC Electricity Cost Calculator
Calculate the cost of running a gaming PC with separate gaming and idle power levels. Add the energy used in each state to estimate daily, monthly and yearly cost.
↗PowerPSU Wattage Calculator
Add estimated component loads to see a power-supply planning range. Wattage and headroom alone do not establish hardware compatibility.
↗PowerUPS Runtime Calculator
Estimate ideal battery-backup time from stored energy and connected load. Compare this approximation with your UPS manufacturer’s runtime curve.
↗Storage
Plan drive capacity, recorded video sizes and streaming allowances.
Video File Size Calculator
Estimate video storage from duration and combined video and audio bitrate. Resolution and frame rate provide context; bitrate determines the size.
↗StorageStreaming Data Usage Calculator
Estimate how much data streaming uses per hour and over your viewing schedule. Compare a sustained bitrate with your monthly data allowance.
↗StorageStorage Calculator
How many games or files fit on your drive?
↗Display & frame timing
Translate frame rate into the time each frame takes.
Choose a calculator for your connection or PC
Start with what you can measure: the file size shown by your app, sustained transfer speed or average power at the wall. Advertised speeds and PSU capacity are not measurements of everyday use.
- Download time estimates a file transfer; use game download time when you want game-size presets and installation guidance.
- Mbps to MB/s converts the rate advertised by your internet provider into the byte units often shown by download apps.
- PC electricity cost uses a single average power figure; the gaming PC tool separates gaming hours from idle hours.
- Video file size estimates recording storage from bitrate; streaming data usage projects ongoing use over a month.
