Plan 721 follows the same structure as Plan 720 but stretched to 25 years, with four SB instalments at 15% of BSA each instead of three at 20%. The longer term has two material effects on economics: the SRB accumulates for 25 years on the full original BSA, which can add meaningfully to total value received; but the FAB rate also rises sharply with duration (LIC's FAB ladder rewards longer terms disproportionately). For a policyholder with a 25-year financial horizon — say, buying a policy at 30 to fund retirement at 55 — Plan 721 can deliver a slightly better XIRR than Plan 720 at the same BSA, because the FAB at 25 years is substantially higher. The four SB windows also provide more granular liquidity anchors than the three in Plan 720.

• Four survival benefit windows (years 5, 10, 15, 20) provide quarterly-decade liquidity milestones — useful for progressively larger anticipated needs (education, wedding, down payment, etc.).
• SRB accumulates for 25 years on the full original BSA — the bonus pool at maturity is materially larger than in Plan 720, partly offsetting the longer lock-in.
• FAB at 25 years is typically 2–4× the FAB at 20 years per the LIC ladder — the 'bonus on staying long' is real and quantifiable.
• The death benefit (max of 125% BSA or 7× annualised premium + vested bonuses) is unaffected by any of the four SBs paid — full protection throughout the 25-year term.
• The 20-year PPT means you stop paying premiums 5 years before maturity — years 21–25 are premium-free, a concrete advantage for pre-retirement savers whose incomes may plateau or decline.
• At 25 years, the XIRR is slightly sensitive to mid-term SRB compression — each 0.25% drop in the effective SRB rate moves the XIRR by roughly 15–20 basis points. Use the optimistic / pessimistic scenario toggle to sense-check your assumptions.
