title: Gearing_Bonus
---
::: mw-parser-output
When producing units for your nation, you will receive a **Gearing
Bonus** for each unit you produce in
[serial](/wiki/index.php?title=Serial_Production&action=edit&redlink=1 "Serial Production (page does not exist)"){.new}
. This represents the specialization and tooling of factories to produce
large production runs of a given type. As you produce more units of the
same type, the amount of time required to produce each consecutive unit
is reduced. Anything that can be built in a long run can benefit greatly
from the gearing bonus. You might even want to start all unit production
in a very long series and then cancel the series when it\'s no longer
needed; this will ensure that you have the option to keep on getting the
gearing bonus.

The gearing bonus only affects time to producing units, not the
[Industrial Capacity](/wiki/Industrial_Capacity "Industrial Capacity")
cost associated with the unit. It also does not apply to non deployable
[province

produced in serial. [Province
improvements](/wiki/Province_improvements "Province improvements"){.mw-redirect}
than can be deployed such as province AA benefit from the gearing bonus;
improvements like factories than can not be moved do NOT benefit from
the gearing bonus.

A little more info about the effect of gearing.

For comparison here is a short tab of a serial production of BB ships;
first column is with full drafted army, second with full standing army
setting:

Drafted Army Standing Army Days for Days for # Days for Days for series ship series ship 1 584 584 1 584 584 2 1139 525 2 1139 525 3 1664 497 3 1664 497 4 2161 467 4 2161 467 5 2628 438 5 2628 438 6 3066 409 6 3066 438 7 3475 379 7 3504 438 8 3854 351 8 3942 438 9 4205 321 9 4380 438 10 4526 321 10 4818 438 11 4847 321 11 5256 438 12 5168 321 12 5694 438

For the first 5 ships the bonus is the same, the gearing bonus maxes out
at the 9th ship (with slider setting for army in the middle this is the
same, at the 9th ship bonus is maxed).

While having the drafted army slider maximized is great for gearing,
there are other benefits that make the standing army preferable in most
circumstances. Standing army gives more organization and less upgrade
time and cost. The last 4 standing army positions also give newly
produced units experience.
