Estimate the time a game patch or update takes to download and apply on your connection.
Gigabytes are converted to megabits by multiplying by 8,000, then divided by the throughput actually achieved. Real transfers never hit line rate because of protocol overhead, disk speed and contention, so the efficiency factor derates it first. A game update quoted at line rate is always optimistic; planning a maintenance window on the derated figure is what stops it overrunning.
Game Update Time
Time = size × 8,000 ÷ (line rate × efficiency), in seconds

This calculator takes 3 inputs: Update or patch size, Connection speed, Achieved share of line rate. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
