Planning for retirement
This calculator projects how large your retirement savings could grow by the time you retire, based on what you have saved today, how much you add each month, and the average return you expect. The longer your money has to compound, the larger the role investment growth plays compared with your own contributions.
The 4% rule
The estimated yearly income figure uses a well-known rule of thumb: that you can withdraw about 4% of your savings in your first year of retirement and adjust for inflation thereafter, with a reasonable chance the money lasts about 30 years. It is a simplification — real safe-withdrawal rates depend on market conditions, your lifespan, and how flexible your spending is.
Things this does not include
Government or state pensions, employer matching, taxes on withdrawals, and inflation are all left out to keep the projection simple. Treat the result as a directional guide to whether you are on track, and revisit it as your income and goals change.
