What is the State Pension Forecast Calculator?
The State Pension Forecast Calculator helps you estimate when you are likely to receive the UK State Pension and how much it could be worth over time. It projects future payments using triple lock assumptions and shows how changes to State Pension Age could affect your retirement income.
How the Calculator Works?
This calculator starts by estimating your State Pension Age based on your date of birth and the current GOV.UK timetable, including known transitions from age 66 to 67 and the planned move to 68. You can also test potential future increases to see how policy changes might affect you.
From State Pension Age onwards, the calculator projects payments year by year using the triple lock, applying the highest of inflation, earnings growth or the 2.5% minimum. You can view results either in future cash amounts or adjusted to today’s money to reflect real purchasing power.
The tool supports partial entitlements, allowing you to model different National Insurance histories or percentages of the full pension. All projections can be exported for further planning.
Step One: Enter Your Personal and Policy Assumptions
Add your date of birth, expected entitlement level and assumptions for inflation and earnings growth. Choose whether to test potential increases to State Pension Age.
Step Two: Review Your State Pension Forecast
See your estimated State Pension Age, the projected pension at that point and a year-by-year forecast through later life.
Step Three: Compare Real and Nominal Outcomes
Switch between today’s money and future cash values to understand how inflation affects the pension’s real spending power.
State Pension Forecast Calculator
Forecast your UK State Pension using triple lock assumptions (inflation, earnings or 2.5% floor) and test State Pension Age increases.
Step 1: 📋 Inputs
Enter your personal details, entitlement information, and assumptions about future inflation and earnings growth. The calculator will estimate your State Pension Age and project your pension from that point onwards.

What if the government increases the State Pension Age? Use this section to see how a later retirement age would affect when you can claim your pension. This is just a “what if” scenario – it doesn’t predict what will actually happen.
Step 2: 📊 Results
View your estimated State Pension Age, forecast amounts, and a year-by-year projection showing how your pension will grow from State Pension Age until age 90 (or your chosen projection length).
💰 Year-by-year forecast
This table shows your State Pension from your State Pension Age onwards, year by year. Each year, your pension increases by the triple lock (the highest of CPI inflation, earnings growth, or 2.5%). The amounts shown depend on whether you’ve selected “Future cash amounts” or “Today’s money” above.
| Tax year | Your age | Triple lock uplift used | Full pension (£/week) | Your pension (£/week) | Your pension (£/year) |

What is the State Pension Forecast Calculator?
It is a UK-specific planning tool that estimates your State Pension Age and projects future payments using triple lock assumptions, allowing you to explore real and nominal outcomes.
How is my State Pension Age calculated?
It is estimated using the current GOV.UK timetable based on your date of birth, including known phased increases.
What is the triple lock?
The triple lock increases the State Pension each year by the highest of inflation, earnings growth or 2.5%.
Can I change the triple lock assumptions?
Yes. You can adjust inflation and earnings growth assumptions to test different scenarios.
What does “today’s money” mean?
It means values are adjusted for inflation so they reflect current purchasing power rather than future cash amounts.
Does this calculate my exact entitlement?
No. It provides an estimate based on assumed entitlement levels. Your actual entitlement depends on your National Insurance record.
Can I model changes to State Pension Age?
Yes. You can add extra years to test the impact of potential future policy changes.
How far into the future does the projection run?
By default, projections run from State Pension Age through to age 90, but you can extend this.
Is the UK State Pension guaranteed to keep the triple lock?
No. The triple lock is a policy choice and may change in the future. This calculator shows projections under current assumptions only.
Why should I use my official forecast instead of the full rate?
Your amount depends on your National Insurance record and can be affected by pre-2016 history, including contracting out. The full new State Pension is not an automatic entitlement for everybody with the same age. Use the GOV.UK forecast as the starting amount, then use this calculator to explore timing and uprating.
Can I take the State Pension early?
No. Unlike many private pensions, the UK State Pension cannot normally be claimed before State Pension age. You can defer it after that age, which may increase later payments under the rules then in force. Any years before State Pension age need to be funded from other income or assets.
Is State Pension taxable?
Yes, it is taxable income, although it is normally paid without tax deducted. HMRC may collect tax through another pension or Self Assessment when your total taxable income exceeds your allowances. Add it to defined benefit pensions and taxable drawdown when planning net income.
What if State Pension age changes after I plan?
Run the current State Pension age and another version where it starts a year later. The rise from 66 to 67 is being phased between 2026 and 2028, and later timetables can be reviewed. Accessible savings give you far more room than a plan that runs out if the date moves by one year.
Can I export the results?
Yes. You can download a CSV file containing the full year-by-year forecast.
Is my data stored?
No. All calculations run locally in your browser and no data is saved or transmitted.

Behind Retirement Calculators
Built from the questions I was asking myself
I'm Ryan, the person behind Retirement Calculators. I started the site after selling an online business and trying to understand what our pensions, ISAs, investments and property actually meant for the way we wanted to live.
The calculators are built around those real decisions: whether you could work less, retire earlier, spend more now or use your money differently. They will not give you a perfect answer, but they can make the trade-offs much easier to see.
Have an idea for a calculator, spotted something that could be clearer, or want to ask me about the site?
