How to Use This Calculator
Copy the current timer and speed values from your account. Enter speedups as total hours. Use the help field only as a clearly understood planning assumption.
Formula & Methodology
Adjusted time equals base hours divided by one plus research speed. Help reduction is applied next, then speedup hours are subtracted. Remaining time is capped at zero.
Example: 120 hours at +50% research speed
A 120-hour timer at +50% speed becomes 80 hours before help and speedups. Eight speedup hours leave 72 hours.
This manual calculator does not import account data, technology tables, VIP bonuses, temporary buffs, event rules, or alliance state.

Frequently Asked Questions
- How does research speed reduce time?
- A +50% bonus divides base time by 1.5. It does not simply subtract 50% from the timer.
- Should temporary buffs be included?
- Only include bonuses that the game will apply when the research begins.
- Does this know each technology cost?
- No. It is a timer and speedup planner using values entered from the game.
- Can remaining time be negative?
- No. The result is capped at zero.
