Are you on track to retire?
This calculator answers three questions: how much you'll have at retirement, how much you'll need for the lifestyle you want, and what to change if there's a gap.
How it works
- Savings phase: your current savings and monthly contributions grow at your pre-retirement return until you retire.
- Income needed: your desired income (in today's money) is increased by inflation until retirement, and keeps rising with inflation each year after.
- Nest egg needed: the amount that, invested at your post-retirement return, can pay that rising income until the age you plan to.
- The gap: the difference, and the extra monthly saving that would close it.
Example
Age 30, retiring at 65 and planning to 90, with 25,000 saved and 500 a month, 7% return before retirement, 5% after and 3% inflation, wanting 40,000 a year in today's money:
| Result | Amount |
|---|---|
| Projected savings at 65 | ≈ 1.19 million |
| First-year income needed (inflation-adjusted) | ≈ 112,600 |
| Nest egg needed | ≈ 2.21 million |
| Extra saving needed | ≈ 566 a month |
| Projected savings last until | age 76 |
Ways to close a retirement gap
- Save more, especially early: money invested in your 30s has decades to compound.
- Retire a few years later: you save for longer and draw down for fewer years.
- Use employer matching in full; it's an immediate return on your money.
- Reduce fees: a 1% lower annual fee can add up to tens of thousands over a career.
These projections are estimates based on constant returns and inflation. They are not financial advice.
