Pension

In The Sims 2, The Sims 3 and The Sims 4, Sims who retire from a career will receive a pension.

The Sims 2
In The Sims 2, an elder Sim who retires will receive a weekly pension that is half the weekly salary of the job he or she retired from. The Sim will receive one-seventh of that each day. This does not appear to be affected by the Skilled Negotiator aspiration benefit.

A retired Sim who takes a part-time job will keep his or her pension; the part-time job will be shown in a second tab on the job panel.

A Sim's pension stops when he or she dies, but will resume if he or she is resurrected.

The Sims 3
In The Sims 3, elder Sims have the option to retire from their careers at any time. Retiring can be done by phone, and when done, everyone in the room will cheer the newly retired Sim. When a retired Sim receives a pension payment appears to depend on when the Sim got paid while working. Sims retired from careers which pay a weekly stipend will get their pension on the same day as the stipend, while Sims retired from careers that pay every workday will receive a daily payment. For most careers, the amount of a Sim's pension is based on the Sim's career level at retirement. However, for stipend-based careers from Ambitions, it may depend on the Sim's average income from that career.

It has been reported that retired Sims continue to receive their pensions while on vacation.

A Sim's pension stops when he or she dies or takes another job.

The Sims 4
Like in previous games, elders may retire from their careers over the phone. Once retired, they will receive a pension daily at the time when they normally come home from work. I aint played the sims 4 how the hell am i supposed to know
