Video Game Backlog Time Estimator

Estimate how many weeks, months, or years it will take to finish your video game backlog based on your library size, average game length, and how much you play each week.

Number of Unplayed Games in Backlog

Average Hours to Complete One Game (Main Story)

Tip: Use HowLongToBeat.com to find averages for your genres.

Hours You Play Per Week

Completion Rate (% of started games you actually finish)

Be honest — many players finish only 50–80% of games they start.

New Games Added to Backlog Per Month

Set to 0 if you plan to stop buying games until backlog is cleared.

#### Formula

Effective Games = Backlog Games × (Completion Rate / 100) Total Backlog Hours = Effective Games × Average Hours per Game Net Hours Added/Week = (New Games/Month ÷ 4.345) × (Completion Rate / 100) × Avg Hours Net Hours Cleared/Week = Weekly Play Hours − Net Hours Added/Week Weeks to Finish = Total Backlog Hours ÷ Net Hours Cleared/Week Months to Finish = Weeks to Finish ÷ 4.345 Years to Finish = Weeks to Finish ÷ 52.18
