Retirement Calculator
Project your potential nest egg by combining today’s savings, monthly contributions, and an expected annual return based on risk tolerance.
Project your savings runway with monthly contributions and a risk-adjusted return.
Future value of recurring savings
FV = P(1 + r/12)^{12y} + PMT × [((1 + r/12)^{12y} − 1) ÷ (r/12)]P is your current balance, PMT is the monthly contribution, r is the annual rate tied to the selected risk profile, and y is years until retirement.
How to use
- Enter your current age and target retirement age to set the timeline.
- Provide current savings, planned monthly contribution, and choose a risk profile.
- Review the projection for total contributions, investment growth, and the estimated nest egg.
Example
Input: Current age = 32, Retirement age = 65, Savings = $40,000, Monthly contribution = $600, Risk profile = Balanced (≈7%)
Output: Projected nest egg ≈ $1,326,719.63 with $1,049,119.63 in growth over contributions

Deep dive & study plan
Retirement Calculator: Model retirement savings with monthly contributions and risk profiles. It's built around retirement, nest egg, future value, so you can go from a raw question to a checked answer without switching tools.
The math behind it: P is your current balance, PMT is the monthly contribution, r is the annual rate tied to the selected risk profile, and y is years until retirement. The core relationship is FV = P(1 + r/12)^{12y} + PMT × [((1 + r/12)^{12y} − 1) ÷ (r/12)], shown above the calculator so you can see exactly how your inputs turn into the result.
To use it well: (1) Enter your current age and target retirement age to set the timeline. (2) Provide current savings, planned monthly contribution, and choose a risk profile. (3) Review the projection for total contributions, investment growth, and the estimated nest egg. Keep your units consistent as you go, and re-run a case you already know the answer to — it's the fastest way to catch a typo before it throws off a result you're relying on.
Worked example: entering Current age = 32, Retirement age = 65, Savings = $40,000, Monthly contribution = $600, Risk profile = Balanced (≈7%) returns Projected nest egg ≈ $1,326,719.63 with $1,049,119.63 in growth over contributions. Try swapping in your own numbers next, especially a case you're unsure about, before you use this for something that matters.

FAQ & notes
Can I change the assumed return?
Yes. Switch the risk profile to conservative, balanced, or growth to adjust the underlying annual return assumption (5%, 7%, or 9%).
Does this include taxes or employer matches?
No. The projection is pre-tax and does not account for employer contributions. Add matching funds to the monthly contribution to include them.
