Retirement savings
Project a savings balance at your chosen retirement age.
How this works
Monthly compound-growth projection with end-of-month contributions and a constant user-assumed nominal return. Optional annual fee drag reduces the assumed nominal rate; yearly contribution growth and annual inflation adjust the projection. Beginning-of-month deposits receive one extra month of growth. Retirement target contribution solves the annuity formula with zero annual contribution growth.
Example
The illustration may use different inputs from the reproducible default inputs listed below.
With no starting savings, $100 saved monthly for 2 years at 0% grows to $2,400. A $4,800 target needs $200 each month.
- Current age
- 40 years
- Retirement age
- 65 years
- Current savings
- 50000 USD
- Monthly contribution
- 500 USD
- Assumed annual return
- 5 %
- Annual fee drag (%)
- 0
- Assumed annual inflation (%)
- 0
- Annual contribution increase (%)
- 0
- Monthly contribution timing
- End of month
- Target balance at retirement
- 1000000
- Projected savings at age 65
- $471,819.38
Contributions use your chosen beginning/end-of-month timing. The retirement target calculation solves a constant monthly contribution with no annual escalation. Annual fee drag is subtracted from the nominal return; contributions increase once each year. Returns and inflation are user assumptions, not forecasts.
Scope and assumptions
Illustrative accumulation only, not financial advice. No tax rules, contribution limits, employer matches, benefits or guaranteed returns. Fees use a simplified annual rate subtraction. Does not estimate sustainable withdrawals.
