Your projected state pension of £10187.84/year covers 50.9% of a £20,000 modest retirement income, or 25.5% of a £40,000 comfortable retirement. The rest must come from private pensions, ISAs, or other savings.
Private savings gap by retirement lifestyle
| Target retirement income | Gap vs state pension | Pot needed (4% rule) | Monthly save (20yr, 5% real) |
|---|---|---|---|
| £20,000 (PLSA minimum) | £9,812.16/yr | £245,304 | £597/mo |
| £40,000 (PLSA moderate) | £29,812.16/yr | £745,304 | £1,813/mo |
| £60,000 (PLSA comfortable) | £49,812.16/yr | £1,245,304 | £3,030/mo |
Monthly figures assume 20 years to retirement, 5% real return (after inflation), and a 4% safe withdrawal rate. Every £1 contributed to a pension gets at least 25% tax relief (more for higher-rate taxpayers), making pensions the most efficient vehicle for closing this gap.

State pension with 31 NI years — explained
With 31 qualifying National Insurance years, your new state pension in 2025-26 is £195.92 per week (£10187.84/year or £849/month). This represents 88.6% of the maximum new state pension of £221.20/week.
To boost your pension to the full £221.20/week, you need 4 more qualifying years. You can achieve this through continued employment, NI credits (for example, through Child Benefit or carer status), or by purchasing voluntary Class 3 contributions at £3,297 in total.
Your qualifying NI years include any year where you paid (or were credited with) NI contributions above the Lower Earnings Limit (£6,396 in 2025-26). Years of employment, self-employment, and certain benefit claims all count.
Building your private pension on top of 31 NI years
At 31 qualifying years, the state pays you £10187.84/year — but the PLSA's retirement living standards suggest a single person needs roughly £15k–£20k for a minimum lifestyle, £31k for moderate, and £43k+ for comfortable. For a £40,000 target on 31 NI years, you need to close a gap of £29,812.16/year, requiring a pension/ISA pot of about £745,304. Saving £1,813/month for 20 years at a 5% real return would get you there. Pension tax relief means a basic-rate taxpayer contributing £100 only costs £80 net; for higher-rate earners, it's just £60 — so the real out-of-pocket cost is much lower than the headline figure. Combine pensions with salary sacrifice to save NI too.
