The terms "pension plan" and "annuity" are often used interchangeably in casual conversation — even by some advisors — but they refer to structurally different products that suit different stages of retirement planning. Getting this distinction right is important for building a coherent retirement income strategy.

A pension plan (also called a deferred annuity plan) is an accumulation vehicle. You pay premiums over your working years — 15, 20, 25 years — and the plan builds a corpus. At a chosen vesting date (retirement), that corpus is either taken as a lump sum, converted into an annuity, or a combination of both. The Kotak Retirement Plan is a pension plan. It's the right product for someone who is still working and building their retirement corpus.

"A pension plan grows your money before retirement. An annuity distributes that money after retirement. You need the first product before the second becomes relevant."

An immediate annuity converts a lump sum into a guaranteed income stream — immediately, with the first payout typically beginning within a month of purchase. You hand over a corpus (either built through a pension plan, from savings, or from the proceeds of a property sale), and in return receive a fixed monthly income for life. The Kotak Lifetime Income Plan is an immediate annuity. It's the right product for someone who has already retired or is retiring imminently and needs to convert savings into income.

The natural sequence: pension plan during your working years, converting to an annuity at retirement. You can also hold both simultaneously — continuing to build through a deferred plan while drawing income from an annuity.

The critical planning consideration: annuity rates are fixed at the time of purchase. Locking in at current rates versus waiting for potentially better rates is a genuine decision. Most financial planners recommend staggered annuity purchases rather than converting your entire corpus at one moment.
