Turn retirement into arithmetic
The usual benchmark at 40 is about three times your salary saved. The better exercise works backward from spending. Estimate what a year of retirement would cost in today's dollars and multiply by 25. That figure, from the long-standing guideline of withdrawing about 4 percent a year, is a rough target for your investments. Then read your Social Security statement, available through an account on the agency's website, which estimates your benefit at different claiming ages. For anyone born in 1960 or later, full retirement age is 67. Claiming at 62 permanently cuts the monthly check by about 30 percent, and each year of delay past 67 raises it 8 percent until 70.
If the numbers fall short, you have three levers: save more, work longer or spend less later. Higher catch-up contribution limits open at 50. A fee-only financial planner who charges by the hour and sells no products is worth a session at this stage.
What the law adds at 40
The federal Age Discrimination in Employment Act protects workers 40 and older at employers with 20 or more employees, and many state laws reach smaller ones. The practical defense is older than the statute: keep your skills current, keep your network warm and keep a record of your results.
The screening calendar
- Blood pressure should be checked at least once a year, with cholesterol and blood sugar on the schedule your doctor sets.
- Breast cancer screening by mammogram is recommended every two years starting at 40.
- Colorectal cancer screening starts at 45 for people at average risk.
- Eye exams matter more now, because difficulty focusing up close typically arrives in the early to middle forties.
Muscle mass declines with each decade unless you resist it, so the strength training twice a week that federal activity guidelines recommend stops being optional.
Documents and direction
Your will, powers of attorney and beneficiary forms may be a decade old and may name the wrong people. If you have children nearing college and parents nearing frailty, you are in the most expensive stretch of life, and retirement saving is the item to defend, since it is the only one that cannot be financed with a loan. Then write down how you would want to spend a typical week at 50 and compare it with how you spend one now. The gap is the agenda.
Note Surveys across many countries find life satisfaction dipping in the forties and climbing again afterward. If the decade feels heavy, that is common and usually temporary.
