What Is a Joint-Life Annuity?
A joint-life annuity is an annuity that pays you a guaranteed income for life, and then continues to pay a proportion of that income to your spouse or partner after you die. It is the most common way for couples to ensure the surviving partner retains a meaningful pension income.
When you purchase a joint-life annuity, you choose the percentage of your income that your partner will receive. The standard options are 50%, 66%, or 100%. The higher the survivor's percentage, the lower your starting income, because the insurer is taking on a greater commitment.
Joint-Life vs Single-Life: The Cost Comparison
Choosing a joint-life annuity over a single-life annuity reduces your starting income. But how much does it actually cost? The table below shows the real pound-for-pound difference using a £200,000 pension pot for a 65-year-old with a partner aged 63.
| Annuity Type | Your Annual Income | Reduction vs Single-Life | Survivor's Annual Income |
|---|---|---|---|
| Single-life (no survivor) | ~£13,600 | — | £0 |
| Joint-life, 50% survivor | ~£12,000 | ~£1,600/yr (12%) | ~£6,000 |
| Joint-life, 66% survivor | ~£11,400 | ~£2,200/yr (16%) | ~£7,500 |
| Joint-life, 100% survivor | ~£10,400 | ~£3,200/yr (24%) | ~£10,400 |

The 50% survivor option is the most popular choice because the cost is relatively modest (roughly 12% of income) while still providing meaningful protection. Consider that a surviving partner living alone typically has lower living costs, so 50% of the original income — combined with their own State Pension — may be adequate.
How the Age Gap Affects Your Rate
The age difference between you and your partner significantly affects the cost of a joint-life annuity. A younger partner is expected to receive survivor payments for longer, which reduces your rate further.
| Your Age | Partner's Age | Age Gap | Annual Income (50% survivor, £200k) |
|---|---|---|---|
| 65 | 65 | Same age | ~£12,200 |
| 65 | 63 | 2 years younger | ~£12,000 |
| 65 | 60 | 5 years younger | ~£11,600 |
| 65 | 55 | 10 years younger | ~£10,800 |
| 65 | 50 | 15 years younger | ~£10,000 |
With a 15-year age gap, the cost of joint-life protection becomes substantial — roughly 26% less than a single-life annuity. In cases of large age gaps, other strategies such as term life insurance alongside a single-life annuity may be more cost-effective.
When a Single-Life Annuity Makes Sense
A single-life annuity is not just for single people. There are legitimate reasons a person in a couple might choose single-life:
- Your partner has their own substantial pension — if they have their own defined benefit pension or large pension pot, they may not need survivor income from yours
- Your partner is older and in poor health — if your partner is unlikely to survive you, the cost of joint-life protection may be wasted
- You have life insurance — a lump sum life insurance payout could provide for your partner more cost-effectively than ongoing joint-life payments
- You have significant other assets — ISAs, property, or other investments that would pass to your partner on death
Joint-Life Annuity with Escalation
You can combine a joint-life annuity with escalation (fixed percentage increases or RPI-linked). This provides both survivor protection and inflation protection, but the starting income is significantly reduced because you are paying for two features.
| Combination (Age 65, £200k pot) | Year 1 Income | Year 10 Income | Survivor Income (50%) |
|---|---|---|---|
| Single-life, level | ~£13,600 | ~£13,600 | £0 |
| Joint-life, level | ~£12,000 | ~£12,000 | ~£6,000 |
| Joint-life, 3% escalating | ~£8,400 | ~£11,290 | ~£4,200 rising |
| Joint-life, RPI-linked | ~£7,200 | Varies | ~£3,600 rising |
A joint-life escalating annuity starting at £8,400 per year is considerably less than a single-life level annuity at £13,600. With smaller pots, this starting income may be insufficient. However, with larger pots (£300,000+), the combination becomes more viable.
Adding a Guarantee Period
A guarantee period (typically 5 or 10 years) works alongside joint-life protection but serves a different purpose. The guarantee ensures payments continue for a minimum period regardless of when you die. On a joint-life annuity, the guarantee applies to the full annuity amount, not just the survivor's portion.
For example, with a 10-year guarantee on a joint-life annuity: if you die after 3 years, the full annuity continues for 7 more years, then drops to the survivor's percentage for the rest of your partner's life. If you die after 15 years, the guarantee is irrelevant and the survivor's percentage applies immediately.
Practical Considerations for Couples
Both Partners Have Pensions
If both you and your partner have pension pots, you could each buy a single-life annuity and rely on the surviving partner's own pension after the first death. This can sometimes provide more total income than two joint-life annuities. Run the numbers both ways before deciding.
State Pension Considerations
Remember that the State Pension does not pass to a surviving spouse (except in limited circumstances for those who reached State Pension age before 6 April 2016). Your partner will receive their own State Pension based on their National Insurance record, but they will not inherit yours. Factor this into your calculations when deciding how much survivor income your partner would need.
Tax Implications
The survivor's annuity income is taxable in their hands. If your partner has little other income, a large portion may fall within their personal allowance (£12,570). If they have other income sources, the annuity income could push them into a higher tax bracket. See our guide on tax on pensions for more.
Alternatives to Joint-Life Annuities
A joint-life annuity is not the only way to protect a partner. Consider these alternatives:
- Drawdown: Funds remaining in drawdown at death can pass to beneficiaries, potentially tax-free if you die before 75
- Partial annuity + drawdown: Use an annuity for guaranteed income and keep the rest in drawdown to pass on death. See our partial annuity strategy guide
- Life insurance: A decreasing term policy could provide a lump sum to your partner, which might be cheaper than the income reduction of a joint-life annuity
- Annuity with guarantee period: A single-life annuity with a long guarantee period (10-20 years) ensures payments continue to beneficiaries for that period
Next Steps
If you are in a couple, the joint-life vs single-life decision is one of the most consequential choices in retirement planning. Get quotes for both options from multiple providers using the Open Market Option, and compare the actual pound difference. Consider your partner's other income sources, their age, and their health. A financial adviser can model different scenarios and help you make the right decision for your specific circumstances.
