How retirement savings are projected
Combining lump sum and monthly contributions
This tool projects two growth streams: your current savings compounding monthly, plus a future value of monthly contributions (an annuity), using the formula Future Value = Savings × (1+r)^n + Monthly × [((1+r)^n − 1) / r], where r is the monthly return rate and n is the number of months until retirement.
When to use this tool
Useful for checking whether you’re on track for retirement, testing different contribution levels, or comparing scenarios with different retirement ages.

Accuracy & limitations
This calculator is built for speed and accuracy, but it's worth understanding what it does and doesn't account for:
- No inflation adjustment. The projected amount is in today’s currency value terms — inflation will reduce its real purchasing power by retirement.
- Constant rate assumption. Real investment returns vary year to year — this projects a smooth, constant-rate outcome for simplicity.
- No taxes or fees. Account fees, taxes on withdrawals, and management costs are not factored into this projection.
Retirement Calculator FAQ
Yes, the Retirement Calculator is completely free with no sign-up required.
No — all calculations happen locally in your browser, and nothing is saved.
No, the projected amount is in today’s value — consider using a lower "real" return rate to roughly account for inflation.
Many long-term investors use a conservative estimate like 6–8% for diversified portfolios, but this varies by risk tolerance and asset mix.
Not directly — this tool assumes continuous monthly contributions until your retirement age.
No. All calculations run entirely in your browser, and nothing you enter is ever sent to a server or stored.
