Which annuity payout option provides the largest periodic income for a given amount of money?

Straight life pays the highest periodic income because the insurer's obligation ends at the annuitant's death, with nothing guaranteed to a beneficiary, so there is no cost for a survivor or refund feature. Life with period certain, joint and survivor, and installment refund all add guarantees that protect a beneficiary, and each of those guarantees reduces the size of the payment. The trade-off is income size versus beneficiary protection.
