I asked ChatGPT what a pension pot would look like if instead of paying NI to the government it had been invested in a Stakeholder pension. See the results here: To estimate the potential pension pot after 35 years of investing National Insurance (NI) contributions into a private stakeholder pension, let’s break it down step by step.
1. National Insurance Contributions (NICs) Assumed Investment
The average UK salary (as of recent estimates) is around £34,000 per year.
The Class 1 NI rate for an employee is 10% on earnings above the primary threshold (currently about £12,570).
This means NI contributions on earnings above the threshold are roughly:
(£34,000−£12,570)×10%=£2,143 per year(£34,000 - £12,570) \times 10% = £2,143 \text{ per year}(£34,000−£12,570)×10%=£2,143 per year
Over 35 years, total contributions would be:
£2,143×35=£75,005£2,143 \times 35 = £75,005£2,143×35=£75,005
2. Investment Growth in a Stakeholder Pension
Stakeholder pensions typically invest in a mix of equities, bonds, and other assets.
A reasonable realistic annual return assumption is 5% per year, net of fees.
Using the future value of annuities formula:
FV=P×(1+r)n−1rFV = P \times \frac{(1 + r)^n - 1}{r}FV=P×r(1+r)n−1
where:
P=2,143P = 2,143P=2,143 (annual contribution),
r=5%r = 5%r=5% (investment return),
n=35n = 35n=35 (years),
we calculate:
FV=2,143×(1.05)35−10.05FV = 2,143 \times \frac{(1.05)^{35} - 1}{0.05}FV=2,143×0.05(1.05)35−1 FV=2,143×5.52−10.05FV = 2,143 \times \frac{5.52 - 1}{0.05}FV=2,143×0.055.52−1 FV=2,143×90.4FV = 2,143 \times 90.4FV=2,143×90.4 FV≈£193,700FV \approx £193,700FV≈£193,700
3. How Much Income Could This Provide in Retirement?
If the person purchases an annuity, at current rates, a £193,700 pension pot could provide around £9,500 per year for life (inflation-linked).
Alternatively, under flexible drawdown, withdrawing 4% per year (a common rule of thumb) would provide £7,750 per year.
Comparison with the State Pension
The UK full new State Pension (as of 2024) is £11,502 per year.
The private pension scenario falls short of this amount.
Conclusion
Investing NI contributions in a private pension could generate a pot of approximately £193,700 after 35 years.
This could provide £7,750 - £9,500 per year in retirement, which is less than the State Pension.
The State Pension remains valuable due to its inflation protection and lifetime guarantee.
If employer contributions were included (as with workplace pensions), the private pot could be significantly larger.
Would you like me to factor in additional scenarios, such as higher returns or employer-matched contributions?

After 50 years of investing the equivalent of National Insurance contributions into a private stakeholder pension:
The total pension pot could grow to approximately £448,633.
Using a 4% safe withdrawal rate, this could provide an annual retirement income of around £17,945.
This is higher than the current full UK State Pension (£11,502 per year), making it a more competitive alternative over a longer timeframe. Let me know if you’d like further refinements, such as different investment return rates or annuity options
