Retirement Planning
Most people are surprised by their State Pension forecast. Not because it is dramatically wrong, but because it is different from what they expected.
Two people with similar careers often end up with very different numbers. This article explains why, what you can do about it, and how to decide whether taking action is worth it before it is too late.
Key facts at a glance

| Years usually needed for the full amount | 35 years, sometimes more |
| Current State Pension age | 66, rising to 67 between 2026 and 2028 |
| Cost to buy one missing year, Class 3, 2025/26 | Approximately £924 |

What is the State Pension — and how does it actually work?
The State Pension is a regular government payment made to people who have reached State Pension age and have a sufficient National Insurance record.
Under the new State Pension system, which applies to anyone reaching pension age after 6 April 2016, the amount you receive is based almost entirely on the number of qualifying years in your National Insurance record.
You build qualifying years by working and paying National Insurance contributions, receiving National Insurance credits, or making voluntary contributions.
The State Pension is paid every four weeks directly into your bank account. It is taxable income, although many people do not pay tax on it because their total income stays below the personal allowance.
Heathcote Financial Planning observation:
The number people quote is rarely the number they receive.
One of the most common misunderstandings is the idea that the State Pension is a standard, predictable amount for everyone.
In reality, contracted-out history, gaps caused by career breaks, and transitional rules can all mean the difference between the headline figure and a person’s actual forecast is significant. That is why checking your forecast is always better than assuming.
What will you personally receive?
The full new State Pension for 2025/26 is £230.25 a week, or £11,973 a year. But “full” is conditional.
Your personal forecast depends on three things:
- Your qualifying years — how many tax years have enough National Insurance contributions or credits to count
- Contracted-out history — if you were contracted out of the Additional State Pension before 2016, this can reduce your starting amount
- Transitional arrangements — if you had a National Insurance record before April 2016, your entitlement may be calculated under both the old and new rules
The single most useful thing you can do right now is check your personal forecast through GOV.UK. That replaces guesswork with a real number and shows whether there may be opportunities to improve it.
A simple way to think about your forecast
At Heathcote Financial Planning, we think this is easiest to understand through three questions:
- What are you on track to receive?
- Why is it that number — and is anything reducing it?
- Is there a cost-effective action worth taking now?
Your forecast answers the first question. Your National Insurance record answers the second. Advice can help with the third.
Who is most likely to have gaps — and why it matters
National Insurance gaps are more common than many people realise. They often affect:
- people who took career breaks for childcare
- self-employed people with fluctuating or low profits
- workers who spent time abroad
- people who worked part-time on low earnings
- those who had periods of unemployment without claiming credits
- people who were contracted out through an employer or pension scheme before 2016
Having a gap does not automatically mean you should fill it.
What matters is whether filling that gap would actually improve your pension entitlement, and whether the cost is a good use of your money.
Can you increase your State Pension — and should you?
There are two main ways to build more qualifying years.
First, if you are still working or receiving eligible credits, you may continue building qualifying years naturally before you reach State Pension age. In many cases, that is enough.
Second, you may be able to pay voluntary Class 3 National Insurance contributions to fill past gaps. For 2025/26, the rate is £17.75 a week, or around £924 for one missing year.
The breakeven calculation most people use
One extra qualifying year adds approximately £6.84 a week to your State Pension, based on the full rate divided by 35.
If you pay around £924 to buy that year, the breakeven point is roughly 2.6 years of drawing the pension.
For many people, that sounds attractive.
But there is an important catch.
What the breakeven calculation misses
The breakeven only works if that missing year actually improves your entitlement.
If you already qualify for the full amount, or if your contracted-out history means the missing year changes nothing, you could pay £924 and gain no benefit at all.
That is why the decision should never be based on cost alone.
When topping up is likely to be worth it
Topping up is more likely to be worth it if:
- you are below the full State Pension amount
- your forecast confirms those specific missing years would improve your entitlement
- you are unlikely to build enough qualifying years before retirement through work or credits
- the cost is manageable relative to the long-term income gain
- no free National Insurance credits are available to fill the same gap
When topping up is likely not worth it
Topping up is less likely to be worth it if:
- you already qualify for the full new State Pension
- your contracted-out history means the gap does not increase your entitlement
- you may be entitled to National Insurance credits instead
- the same money would deliver better value elsewhere
- you are close to State Pension age and may not recoup the cost
- you have not verified whether the gap actually affects your forecast
The deadline most people do not know about
In most cases, you can only go back six tax years to fill National Insurance gaps.
Once that window has passed, those years are usually lost.
If you are in your late fifties or early sixties and have not yet reviewed your National Insurance record, the time to act is now, not after retirement when your options are much more limited.
Heathcote Financial Planning observation:
The clients who regret this most are often not the ones who topped up unnecessarily.
They are the ones who assumed everything was fine, waited too long, and later discovered gaps they could no longer fill.
A short check today can prevent years of lower retirement income.
How the State Pension fits into a realistic retirement income
The full State Pension of £11,973 a year is a valuable foundation, but it is rarely the whole picture.
For context, the Pensions and Lifetime Savings Association (PLSA) Retirement Living Standards for 2024/25 suggest that a single person may need approximately:
| Standard of living | Approximate annual income |
|---|---|
| Minimum | £14,400 |
| Moderate | £31,300 |
| Comfortable | £43,100 |
At the full State Pension level, you may cover a minimum standard, but not much more.
For most people, the State Pension needs to sit alongside private pensions, savings, investments, or other assets.
That is why the State Pension conversation is really part of a broader retirement planning conversation.
Five persistent myths about the State Pension
| Myth | Fact |
|---|---|
| “If I’ve worked for decades, I’ll automatically get the full State Pension.” | Not necessarily. Entitlement depends on your National Insurance record, and contracted-out history before 2016 can reduce what you receive. |
| “35 years always means the full amount.” | Often, but not always. Some people need more than 35 qualifying years because of how older rules interact with the new system. |
| “Buying missing years is always good value.” | No. Voluntary contributions do not always increase your pension. In some cases, they make no difference at all. |
| “The State Pension should cover my retirement.” | For most people, it is a foundation, not a full retirement income. |
| “I can check my forecast any time — there’s no rush.” | There is a deadline. In most cases, you can only go back six tax years to fill gaps. |
The Heathcote Financial Planning six-step decision framework
Before paying voluntary contributions or making any related decision, this is the process we recommend:
| Step | Action | Why it matters |
|---|---|---|
| Step 1 | Check your State Pension forecast | This replaces guesswork with a real number. |
| Step 2 | Review your National Insurance record | This shows where gaps are and which years may matter. |
| Step 3 | Check for free credits first | Carer’s Credit, Child Benefit, and other credits may fill gaps at no cost. |
| Step 4 | Model the cost versus the gain | One missing year may cost around £924 and add around £6.84 a week. |
| Step 5 | Consider opportunity cost | The money may be better used elsewhere depending on your wider plan. |
| Step 6 | Get advice before paying | Once paid, voluntary contributions are generally not refundable. |
Why Step 6 matters most
If you pay for years that do not improve your pension, the money is gone.
That is the step people most often skip, and it can be the costliest mistake.
Frequently Asked Questions
How many National Insurance years do I actually need?
Usually 10 qualifying years to receive any State Pension, and 35 qualifying years for the full amount. However, some people need more than 35 because of contracted-out history before 2016.
I was contracted out — how does this affect me?
If you were contracted out, your starting amount under the new State Pension may be reduced. That can mean you need more than 35 years to reach the full amount.
Can I check my National Insurance record online?
Yes. You can view your record online through your personal tax account.
What if I am approaching retirement now?
The urgency is higher. Check your forecast immediately, identify any gaps, and understand your options before paying anything.
What happens to the State Pension if I defer it?
If you defer claiming beyond State Pension age, your weekly amount increases. Whether that is sensible depends on your health, other income, and tax position.
Does the State Pension count as taxable income?
Yes. It is taxable, although it is paid gross. If your total income exceeds the personal allowance, income tax may apply.
Can I get National Insurance credits instead of paying?
Potentially, yes. Credits may be available for caring responsibilities, unemployment, and other circumstances. They are always worth checking before spending money on voluntary contributions.
What we see in practice
These are patterns we regularly see when helping people with retirement planning:
- contracted-out history is often the most misunderstood factor
- people often check their forecast later than they should
- breakeven calculations are often done before confirming whether the missing year helps
- State Pension timing can affect how private pensions and other income are drawn
That is why this is rarely just a State Pension issue.
It is a broader planning decision about retirement income, tax, timing, and financial flexibility.
