## 先懂计息
- [什么是 IUL（指数型万能寿险）：结构、计息、费用与风险](/overview/): 指数型万能寿险（IUL）是一张终身寿险保单：身故保障之外，有一个按合同公式参考指数表现计息的账户价值。本文从定义出发，讲 IUL 的三层结构、保费如何变成账户价值、指数计息的四个参数、费用从哪里扣、哪些是保证哪些不是、与传统 UL/VUL/ILP/分红终身寿的区别，以及适合与不适合的人。
- [IUL 指数计息怎么算：分段、点对点、锁定日与归零](/crediting/): IUL 的指数利息不是直接持有指数，而是按合同公式在每个分段期（常见一年）比较起止两个指数点位，经参与率、封顶率、利差与下限处理后一次性计入。本文解释分段、锁定日、点对点、归零与“锁定不回撤”的真实含义，股息为何不计入，以及分段中途提款会怎样。
- [封顶率、参与率、利差与下限：四个参数如何互相抵消](/caps-floors/): 封顶率、参与率、利差与下限是决定 IUL 指数利息的四个参数：参与率决定参与多少涨幅，封顶率决定最多计入多少，利差先扣掉一段，下限决定最少计入多少。本文用同一组指数情景演示四个参数如何互相抵消，说明计算顺序为何重要、哪些值是保证的，以及比较产品时该核对什么。
- [IUL 的指数选项：S&P 500、波动率控制指数与多资产指数怎么比](/indices/): IUL 常见的指数选项分三类：传统价格指数（如 S&P 500）、波动率控制指数（如目标波动率 6% 的 Engle 系列）与多资产指数。本文解释波动率控制如何调整敞口、超额回报与价格回报的差别、回测与实盘数据为什么要分开看，以及美国 AG 49-A 对历史数据展示的限制。
- [保险公司怎么“买”出指数收益：期权预算、对冲与参数重设](/option-budget/): IUL 的指数利息来自保险公司用一般账户利息购买的期权，而不是账户里真的买了股票。本文解释期权预算如何由债券收益、违约成本、费用与利润目标决定，看涨期权价差如何复制“0% 下限 + 封顶”的形态，利率与波动率如何影响参数，以及参数重设与美国 AG 49-A 的监管视角。

## 看懂成本与数字
- [IUL 的 COI 与费用：保费费用、保单费、保险成本、退保费用与忠诚结算率](/charges/): IUL 的费用大致分四类：按保费收的保费费用、按保额或固定金额收的保单费、按净风险保额收的保险成本（COI），以及退保与提款费用；部分产品另有忠诚结算率。本文逐项解释计费基数、收取时间与是否保证，说明 COI 如何计算、为何随年龄上升，以及账户不足以扣费的后果。
- [怎么读 IUL 利益演示：两套数字、演示利率与失效年龄的 12 项核对](/illustration/): IUL 利益演示通常有保证列与演示列两套数字。本文给出 12 项核对：演示利率的含义、保证列失效年龄、退保价值与账户价值的差、费用表、指数参数与保证最低值、贷款提款假设，并说明新加坡 LIA 对非分红万能寿险演示的要求，以及与美国 AG 49-A 替代情景的异同。
- [IUL 保单贷款与提款：机制、利息、对保障的影响，以及与保费融资的区别](/policy-loans/): 保单贷款是向保险公司借出自己保单的一部分价值，债权人是保险公司；保费融资是向银行借外部资金缴保费。本文解释新加坡 IUL 保单贷款的条件、利率类型、利息资本化、对计息与身故赔偿的影响、提款与贷款的区别，以及两种杠杆叠加时风险如何放大，并附核对清单。
- [IUL 会不会“自己失效”：不失效保证、最低保费、宽限期与账户归零](/lapse/): IUL 不会因为指数下跌直接失效，但会因为账户价值扣不起费用而终止。本文解释失效的触发条件、不失效保证保什么与附带条件、灵活缴费的最低保费要求、宽限期与复效、保证列显示失效年龄的含义，以及贷款、提款等操作如何影响持续性，并附年度检视指标，适用于新加坡销售的 IUL。

## 判断与落地
- [IUL vs 传统 UL vs VUL vs 分红终身寿 vs ILP vs 定期寿险：同口径对比](/compare/): 同为寿险，IUL、传统 UL、VUL、分红终身寿、零售 ILP 与定期寿险在“谁决定增值、有没有下限与封顶、费用结构、保证程度、演示方式、流动性、能否融资、监管分类与 PPF 处理、适合谁”上差别很大。本文用一张十一维对比表与逐项解释，帮助读者先定位自己需要的是哪一类，再去 iul.sg 看具体产品参数。
- [IUL 适合谁：五个典型场景与不适合的情形](/scenarios/): IUL 不是给所有人的产品。本文用五个匿名化、假设化的场景说明它常被讨论的用途——企业主的传承流动性、持有美元资产的跨境家庭、把保障与长期配置放在同一张合同里的成熟投资者、多代持有与受益安排、把 IUL 作为保障组合一部分的家庭——并明确写出不适合的情形：短期要用钱、要求回报有保证、无法承受补缴与费用上升的人。
- [IUL 投保流程：从需求确认到年度检视的七个步骤](/process/): IUL 的投保比普通寿险多出两个环节：在统一口径下核对两套演示数字，以及为指数账户做配置。本文按七个步骤说明每一步的文件、责任方、时间与常见卡点，重点放在 IUL 独有的环节：锁定日与保费到账日的先后、分段起点、账户分配、参数重设通知与年度结单的读法。
- [IUL 在新加坡与美国分别受什么规则约束：LIA 两套演示、PPF、认可投资者与 AG 49-A](/rules/): 新加坡把 IUL 归为非分红万能寿险，利益演示须按 LIA 指引给出“保证结算利率 + 最高费用”与“当前结算利率 + 当前费用”两套数字，保单持有人保障计划只保保证利益。本文整理新加坡与美国 AG 49-A 的规则、认可投资者的角色，以及两地差异。
- [关于 IUL 的 12 个常见误区](/misconceptions/): 围绕 IUL 的说法里有不少似是而非的表述：0% 下限等于不会亏、演示利率就是每年的收益、融资利率低于演示回报就是套利、IUL 的收益不用交税、参与率越高越好。本文逐条拆解 12 个常见误区，说明错在哪一步，以及在合同和利益演示的哪一栏核对。

## EN edition
- [Caps, participation rates, spreads and floors: how the four parameters offset one another](/en/caps-floors/): Cap, participation rate, spread and floor are the four parameters that set IUL index interest. Using one set of index scenarios, this guide shows how they offset one another, why the order of calculation matters, which values are guaranteed and what to check when comparing products.
- [IUL cost of insurance and charges: premium charge, policy charge, COI, surrender charge and loyalty crediting rate](/en/charges/): IUL charges fall into four broad groups: the premium charge, the policy charge, the cost of insurance (COI) on the net amount at risk, and surrender and withdrawal charges; some products add a loyalty crediting rate. This guide explains each charge's basis, timing and guarantee status, how COI is calculated and why it rises with age.
- [IUL vs traditional UL vs VUL vs participating whole life vs ILP vs term life: a like-for-like comparison](/en/compare/): IUL, traditional UL, VUL, participating whole life, retail ILPs and term life differ on who sets the growth, floors and caps, charges, guarantees, illustrations, liquidity, financing, regulatory class and PPF treatment. An eleven-row table and notes help you place your need before comparing products on iul.sg.
- [How IUL index crediting works: segments, point-to-point, lock-in dates and zero years](/en/crediting/): An IUL does not hold the index. Each segment, commonly one year, compares the index at its start and end, applies participation rate, cap, spread and floor, and credits the result once. Covers segments, lock-in dates, zero years, dividends and mid-segment withdrawals.
- [Indexed universal life (IUL): frequently asked questions](/en/faq/): Twenty-eight answers on how indexed universal life works: index crediting, caps and floors, charges, illustrations, loans, lapse, Singapore rules and tax.
- [IUL glossary (100+ terms, English and Chinese)](/en/glossary/): More than 100 terms on indexed universal life (IUL), given in English and Chinese and arranged in eight groups: basic concepts, accounts and crediting, crediting parameters, indices and options, charges, illustrations and guarantees, loans and persistency, and regulation, protection and tax. Each entry is a neutral definition covering segments, cap rates, participation rates, the option budget, no-lapse guarantees, the PPF and AG 49-A.
- [How to read an IUL benefit illustration: two scales, the illustrated rate and 12 checks including lapse age](/en/illustration/): An IUL benefit illustration usually carries two sets of numbers, a guaranteed column and an illustrated column. This guide gives 12 checks covering the illustrated rate, lapse age in the guaranteed column, surrender value versus account value, the charges table, index parameters, loan and withdrawal assumptions, LIA requirements and how U.S. AG 49-A differs.
- [IUL index options: how S&P 500, volatility-controlled and multi-asset indices compare](/en/indices/): IUL index options fall into three types: traditional price indices such as the S&P 500, volatility-controlled indices such as the Engle 6% series, and multi-asset indices. This guide explains exposure control, excess versus price return, why backtests and live data differ, and the U.S. AG 49-A limits on historical data.
- [Will an IUL lapse on its own: no-lapse guarantees, minimum premiums, the grace period and a zero account value](/en/lapse/): An IUL does not lapse simply because the index falls, but it ends when the account value cannot cover charges. This guide explains what triggers lapse, what a no-lapse guarantee covers and its conditions, minimum premiums on flexible-premium plans, the grace period and reinstatement, what a lapse age in the guaranteed column means and how loans and withdrawals affect sustainability, with annual review indicators. It applies to IULs sold in Singapore.
- [Twelve common misconceptions about IUL](/en/misconceptions/): Many statements about IUL are only partly true: that a 0% floor means you cannot lose money, that the illustrated rate is what you earn each year, that borrowing at a rate below the illustrated return is arbitrage, that IUL returns are not taxed, that a higher participation rate is always better. This article takes apart twelve common misconceptions, shows where each goes wrong and where in the contract or benefit illustration to check.
- [How insurers 'buy' index returns: the option budget, hedging and parameter resets](/en/option-budget/): IUL index interest comes from options bought with interest earned on the insurer's general account, not from shares held in the policy. This guide explains how the option budget is set by bond yield, default cost, expenses and profit target, how a call spread replicates a floor-plus-cap payoff, and how parameter resets and U.S. AG 49-A work.
- [What is indexed universal life (IUL)? Structure, crediting, charges and risks](/en/): Indexed universal life (IUL) credits its account value by a contract formula tied to an index. How it works, what it costs, and what is and is not guaranteed.
- [IUL policy loans and withdrawals: mechanics, interest, effect on cover and how they differ from premium financing](/en/policy-loans/): A policy loan borrows part of your own policy's value from the insurer; premium financing borrows outside money from a bank to pay premiums. This guide explains the conditions and interest types of IUL policy loans in Singapore, interest capitalisation, the effect on crediting and the death benefit, loans versus withdrawals, and how layering two forms of leverage magnifies risk, with a checklist.
- [How to apply for an IUL: seven steps from confirming the need to the annual review](/en/process/): Applying for an IUL involves two stages that ordinary life cover does not: checking the two illustration scales on a common basis, and allocating the index account. This guide sets out seven steps with the documents, responsible parties, timing and common sticking points, concentrating on what is specific to IUL: lock-in date versus premium receipt date, segment start, account allocation, reset notices and how to read the annual statement.
- [Rules governing IUL in Singapore and the United States: the two LIA illustration scales, the PPF, accredited investors and AG 49-A](/en/rules/): Singapore classes IUL as non-participating universal life. Benefit illustrations must follow LIA guidelines and show both a guaranteed crediting rate with maximum charges and a current crediting rate with current charges, while the Policy Owners' Protection Scheme covers guaranteed benefits only. This article sets out the Singapore rules, US AG 49-A, the role of accredited investors and the differences between the two.
- [Who is IUL for? Five typical scenarios and when it does not fit](/en/scenarios/): IUL is not for everyone. Five anonymised, hypothetical scenarios show where it is usually discussed: liquidity for a business owner's estate, a cross-border family holding USD assets, an experienced investor, multi-generation ownership and nomination, and a family adding IUL to a cover portfolio. The article also states who it does not suit: money needed soon, anyone who needs returns to be guaranteed, and anyone who cannot meet top-ups or rising charges.
- [Register of sources](/en/sources/): The register of official documents and public pages cited by the IUL Academy, grouped into Singapore regulation and industry guidelines, insurers' public materials, index providers, overseas regulation and research, tax and reporting, and market data. It lists publisher, title, date, link, where each is used and verification status, with a separate list of items still to be verified or with restricted access, so readers can check and cite each one.
