Retirement Calculator

Planning for retirement can feel overwhelming, but breaking it down into clear numbers makes it manageable. Our retirement calculator is designed to help you visualise your financial future by estimating how your current savings and monthly contributions will grow over time through the power of compound interest.

Whether you are just starting your career and want to see the long-term impact of small monthly contributions, or you are nearing retirement and need to verify if your nest egg will support your desired lifestyle, this tool provides the clarity you need to make informed financial decisions.

Three modes cover every scenario: Savings Projection for a full year-by-year growth chart, How Much? to calculate the exact portfolio size your retirement income requires, and Am I On Track? to compare your projected balance directly against your goal.

The calculator now also shows an inflation-adjusted estimate in projection modes. This helps separate the future account balance from its likely buying power, which is especially important when your retirement date is decades away.

Imagine a 35-year-old with GBP 40,000 already saved who contributes GBP 500 per month until age 67. At a 5% annual return, the final pot may look substantial, but the inflation-adjusted figure can feel much smaller in today's spending power.

That difference is the reason retirement planning should focus on income, not only the final balance. A large future number is only useful if it can support housing, food, healthcare, travel, family help, and unexpected costs after work ends.

Retirement shortfalls are easier to fix early. A gap at age 35 may be addressed by a modest monthly increase, while the same gap at age 60 may require delayed retirement, lower spending, part-time work, or a more aggressive savings plan.

The calculator is also useful for stress testing. Try lower returns, higher inflation, or a shorter contribution period to see how sensitive your plan is to conditions outside your control.

Start by checking whether you are capturing any employer pension match, then review your monthly contribution rate, investment fees, and retirement age assumption. Even a one percentage point increase in savings rate can compound meaningfully over decades.

Keep retirement projections realistic. Include inflation, avoid assuming unusually high returns, and revisit the plan after major life changes such as buying a home, changing jobs, becoming self-employed, or reducing working hours.
