How Long Does It Take to Download 10 GB?
Find out how long a 10 GB download will take on your Wi-Fi or Ethernet connection. Common for 4K video streams, PC software, and indie games.
Quick Answer: A 10 GB file takes on a typical 100 Mbps broadband connection, and finishes in on a Gigabit (1,000 Mbps) fiber connection (assuming 90% real-world efficiency at and write speed).
How Download Time Is Calculated
Time = (File Size in bits) / (Speed in bits/sec × 0.90)To calculate how long 10 GB takes, convert the file size to Megabits and divide by sustained throughput in 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): 100 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)

Frequently Asked Questions
How long does it take to download 10GB at 100 Mbps?
At 100 Mbps, a 10GB file contains 80,000 Megabits. With realistic 90% efficiency, it takes approximately 14 minutes and 49 seconds (theoretical: 13 mins 20 secs).
How long does 10GB take on 1 Gbps fiber?
On a 1 Gbps fiber line with 90% efficiency, a 10GB download finishes in roughly 1 minute and 29 seconds.
