About This Retirement Savings Calculator
This retirement savings calculator focuses on the accumulation phase: how your savings could grow before retirement.
Enter your current savings, monthly contribution, years until retirement, and expected annual return. The calculator estimates your projected balance, total contributions, and investment growth.
This is separate from a full retirement calculator because it does not model withdrawals, income needs, tax, or pension rules.
How to Use This Calculator
- 1
Enter current savings
Add the amount already saved for retirement.
- 2
Add monthly contributions
Enter how much you expect to add each month.
- 3
Set the time period and return
Choose the number of years until retirement and expected annual return.
- 4
Review the projection
Check projected balance, total contributions, investment growth, and yearly results.
Retirement Savings Example
Suppose you already have £25,000 saved and add £400 per month for 25 years. If the account grows at an average 6% per year before inflation and tax, the projected balance would be much higher than contributions alone because each year's growth can also earn growth later.
The important split is between money you contribute and money generated by investment growth. If the projection depends mostly on a very high assumed return, it may be worth testing a lower return to see whether your plan still works.
Ways to Improve the Projection
The highest-impact levers are usually starting earlier, increasing contributions, reducing investment costs, and making sure employer matches or pension contributions are not missed.
Run the calculator with small contribution increases, such as £50 or £100 more per month. Over a long time period, modest changes can produce a surprisingly large difference because compounding has more years to work.
Frequently Asked Questions
What does this calculator estimate?v
It estimates how retirement savings could grow before retirement using regular contributions and compound returns.
Does this include inflation?v
No. The result is shown in nominal terms and does not adjust for inflation unless you manually lower the expected return.
Does this include tax or pension rules?v
No. It does not include pension allowances, tax relief, withdrawals, or scheme-specific rules.
Is this the same as a retirement calculator?v
No. This calculator focuses on savings growth before retirement. A broader retirement calculator may also estimate income needs and withdrawals.
