Retirement savings calculator
Saving into a pension over decades makes compounding the main character, and this projects where that ends up. Enter your current pot, the amount you contribute each month, any employer match, and the annual return you expect, then set how many years until you retire. It grows the pot month by month and shows the projected balance at retirement, separating what you and your employer paid in from what investment growth added. Use it to gauge whether your current saving rate is on track, or to see what an extra contribution could be worth in the long run.
A projection, not a promise. Real returns vary and inflation reduces future spending power. Not financial advice.
How it works
- Enter your current pot value and your regular monthly contribution.
- Add an employer match if you receive one, as a percentage of what you pay in, plus an expected annual return.
- Each month the pot earns one month of growth, then your contribution and any match are added.
- This repeats until your retirement age, with growth compounding on a steadily larger balance.
- The result splits the final pot into total contributions and the portion that came from growth.
each month: pot = pot x (1 + r/12) + contribution + employer match
The pot grows one month at a time. It first earns a month of return at the annual rate divided by twelve, then your contribution and any employer match are paid in. Repeating this to retirement lets growth compound on a steadily larger balance. The final pot is then split into the money paid in, by you and your employer, and the part that came purely from investment growth.
- r
- annual investment return as a decimal
- contribution
- your own monthly payment in
- employer match
- employer payment, a share of yours
Retirement saving reference points
| UK auto-enrolment minimum | 8% of qualifying pay | 3% employer, 5% you |
| Long-run global equity return | ≈ 5 to 7% a year | before inflation, not guaranteed |
| Rule-of-72 doubling at 6% | ≈ 12 years | for a pot to double |
| Common UK access age | 57 from 2028 | rising from 55 |
Worked example
10,000 already saved, 500 a month, 6 percent return over 30 years: a projected pot of roughly 562,000. Of that, about 190,000 is money paid in and the remaining 372,000 is investment growth, which shows how much the long time horizon does the heavy lifting.
Key facts
- Over a long horizon most of a pension pot tends to come from growth, not from the cash paid in.
- An employer match is effectively extra pay, so missing out on it leaves money on the table.
- The earliest contributions compound the longest, which is why starting young matters so much.
- These figures are nominal, so inflation will reduce what the final pot actually buys.
Tips
- Contribute at least enough to capture the full employer match before saving anywhere else.
- Use a cautious return as well as an optimistic one, since markets fall as well as rise.
- Nudge the monthly contribution up after a pay rise, while the higher figure still feels new.
- Mentally discount the headline pot for inflation, or assume a lower real return, to gauge its true worth.
Frequently asked questions
What return should I assume?+
Long-run global stock market returns have averaged around 5 to 7 percent a year before inflation, but nothing is guaranteed and values fall as well as rise. Running a lower figure gives a more cautious, arguably safer, projection.
What is an employer match?+
Many workplace schemes, such as a US 401(k) or a UK workplace pension, pay in on top of your own contribution up to a set limit. It is effectively free money, so including it shows the fuller picture.
Does it account for inflation?+
No, the figures are nominal. A pot of 562,000 in 30 years will buy less than the same sum today, so mentally discount the headline, or assume a lower real return to approximate it.
Can I see the effect of saving more?+
Yes. Nudge the monthly contribution up and re-run it. Because the extra compounds for the full term, even a modest increase early on can add a surprising amount by retirement.
Things to watch
- This is general information, not financial advice, and not a guaranteed outcome.
- Investment values rise and fall, and a run of poor years near retirement can dent the final pot.
- The projection is nominal and ignores charges, so real spending power and net returns will be lower.
