When to Start a Pension If You're Self-Employed
The Power of Starting Early
Compound growth is the most powerful force in pension saving. Money invested early has decades to grow, with returns generating their own returns. Starting even five years earlier can make a dramatic difference to your final pot.
Consider two self-employed people who both contribute £200 per month to a pension with 5% annual growth:
- Person A starts at 25: pot at age 67 = approximately £304,000
- Person B starts at 35: pot at age 67 = approximately £178,000
Person A contributes £24,000 more in total (10 extra years × £2,400), but their pot is £126,000 larger. That extra £102,000 comes entirely from compound growth on the earlier contributions.
Common Excuses (and Why They Do Not Hold Up)
"I can't afford it right now"
You do not need to start with large amounts. Even £50 per month is £600 per year, plus tax relief. With 5% growth, £50 per month from age 30 grows to approximately £76,000 by age 67. That is a meaningful sum, and you can increase contributions as your income grows.
"I'll start when my business is more established"
Your business may always feel like it needs more investment. Meanwhile, you lose years of compound growth. Start small now and increase later.
"I need the cash for my business"
There is a balance between investing in your business and investing in your future. A small pension contribution — even 5% of your profit — is unlikely to harm your business but will significantly help your retirement.
"I'll make it up later"
You can, but it costs much more. To have the same pot at 67, starting at 45 instead of 25 requires roughly three times the monthly contribution. The maths does not favour procrastination.
How to Start with Variable Income
Self-employed income is rarely consistent. Here is how to handle that:
Set a Minimum Contribution
Choose an amount you can afford even in your leanest months. This might be £50 or £100 per month. Set up a direct debit and treat it as a fixed expense.
Top Up in Good Months
After a profitable month or a large client payment, make a one-off additional contribution. Most pension providers accept lump sum payments at any time.
Annual Lump Sum Strategy
Some self-employed people prefer to make a single annual contribution at tax year end, once they know their final profit figure. This works, but you lose the benefit of having money invested throughout the year. A combination of small regular contributions plus a year-end top-up is often the best approach.
