Compare two retirement plans

Two versions of a retirement plan, side by side, each run through the calculator on the home page. The example is one person retiring at 62 or at 67. Change any number in either column.

Plan APlan B
Starting balance ($)
Spending a month ($) savings pay what Social Security does not
Annual return (%) −10 to 20
Inflation (%) −5 to 15
Tax on withdrawals (%) 0 to 50

Social Security from age

The example: retiring at 62 or at 67

Plan A retires at 62. It has $500,000 and spends $5,000 a month. Social Security starts at once, at $1,750 a month, and savings pay the rest.

Plan B keeps working to 67. The same $500,000 grows at 5% for five more years, to about $638,000, with nothing added.

Plan B's $2,500 a month is the full Social Security benefit at 67. Claimed at 62, the same record pays 70% of it, which is Plan A's $1,750. Those percentages hold for anyone born in 1960 or later.
