Download Time on a 25 Mbps Connection
Evaluate real download speeds on a 25 Mbps connection, the FCC benchmark speed for basic residential broadband.
Quick Answer: On a 25 Mbps (Standard Cable (DOCSIS) or Fast 4G LTE mobile broadband.) connection, a 10 GB file finishes in and a 50 GB game takes under standard real-world network conditions.
How Download Time Is Calculated
Time = (File Size in bits) / (Speed in bits/sec × 0.90)To calculate transfer times at 25 Mbps, divide file size in Megabits by 25 Mbps.
Convert to Bits
Multiply file size in Bytes by 8 to get total bits: 10 GB × 8,000,000,000 bits
Apply Speed & Overhead
Multiply network speed by real-world efficiency (typically 90% due to TCP/IP packet headers): 25 Mbps × 0.90
Divide to Find Duration
Divide total bits by effective throughput: 13 min 20 sec (theoretical) / 14 min 49 sec (with 90% real-world efficiency)
