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.
Tip: Use HowLongToBeat.com to find averages for your genres.
Be honest — many players finish only 50–80% of games they start.
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
Assumptions & References
- Average game length data sourced from HowLongToBeat.com; typical main-story lengths range from ~8 hrs (short indie) to ~60+ hrs (RPGs).
- A month is approximated as 4.345 weeks (365 ÷ 12 ÷ 7) and a year as 52.18 weeks.
- Completion rate accounts for games you start but abandon — industry surveys suggest the average player completes 50–80% of games they begin (source: EEDAR / Nielsen game engagement studies).
- New games added per month are assumed to be purchased/acquired at a constant rate throughout the year (e.g., sales, subscriptions like Game Pass or PS Plus).
- The calculator uses "main story" hours as the baseline. Add 30–50% for completionist runs.
- If net hours cleared per week ≤ 0, the backlog grows indefinitely and no finish date can be calculated.
- This tool does not account for replays, multiplayer-only titles, or games with no defined endpoint.
