Production - Hearts of Iron 4 Wiki

As the in-game modifier describes, the retention bonus is applied as a percentage of the loss in production efficiency (e.g. 10% retention incurs a 90% loss, so a 10% bonus would reduce the loss by 10% of 90% or 9%. This would give you a new retention of 19%.) The new Production Efficiency can be calculated in three steps.
