Estimate how a pension-style retirement balance may grow from your current age to retirement if you and your employer keep contributing monthly and the account earns a steady average annual return. Results are estimates only.
What This Calculator Estimates
This calculator estimates the future value of a pension-style savings balance by combining the current balance, monthly personal contributions, employer monthly contributions, and a steady annual return assumption until retirement age.
Formula / Method Used
The estimate uses monthly compound growth until retirement:
- Monthly rate = annual return / 12
- Each month, the balance grows by the monthly rate
- Then the monthly personal and employer contributions are added
- Investment growth = projected retirement balance - current balance - all contributions
Worked Example
If you are 40, plan to retire at 65, already have $120,000 saved, contribute $500 per month, receive $300 per month from your employer, and assume a 6% annual return, the calculator compounds that balance monthly for 25 years while adding both contribution streams each month.
What the Result Means
The projected balance shows the estimated account value at retirement age. Personal and employer contribution totals show how much was directly added over time. Investment growth shows the portion of the final balance that comes from compounded returns rather than direct contributions.
Common Mistakes
- Confusing a pension balance estimate with a guaranteed monthly pension payout.
- Using a return assumption that is too optimistic.
- Ignoring changes in contribution rates over time.
- Forgetting that real accounts can include fees and taxes.
