The Net Worth Peak
Your net worth should peak between 45 and 60, after which you spend down deliberately toward zero.
The Net Worth Peak framework replaces the traditional retirement planning question of 'how much do I need to save?' with 'when should I stop saving and start spending?' The framework argues that your net worth peak should be treated as a date tied to your biological age, not a dollar amount, because focusing on a number creates an endlessly moving goalpost.
Perkins' simulations across dozens of hypothetical scenarios show that for most people, the optimal net worth peak occurs between ages 45 and 60. After this point, you should begin spending more than you earn, drawing down your savings while you still have the health to enjoy experiences. Continuing to accumulate wealth beyond this peak means you are trading health and free time (which are declining) for money (which is growing), a trade that produces diminishing returns on fulfillment.
The framework does not mean quitting your job at 45. You may love your work and choose to continue. But even if you keep earning, you must ramp up spending to match, ensuring that your net worth begins declining rather than continuing to grow. The key insight is that traditional retirement planning fixates on the accumulation phase while ignoring the decumulation challenge, leaving people psychologically unprepared to spend down the savings they worked decades to build.
- Your net worth peak is a date, not a dollar amount
- For most people, the optimal peak occurs between ages 45 and 60
- Continuing to accumulate wealth past the peak trades declining health for growing money, a bad deal
- A numerical target creates an endlessly moving goalpost
- After the peak, spending must exceed earning to reach zero by death
- Decumulation is psychologically difficult but essential for maximum life enjoyment
- Verify you have met the survival thresholdCalculate your survival threshold (0.7 x annual survival cost x years remaining). If you have met or exceeded this, you are ready to think about your peak. If not, continue saving with this target in mind.
- Assess your biological ageConsult your doctor for objective health assessments. Your biological age may differ significantly from your chronological age, and this determines when your peak should occur. Healthier people can peak later; those with health issues should peak earlier.
- Set your peak dateBased on your health, earnings trajectory, and life expectations, choose a specific age for your net worth peak. This is when you transition from accumulation to decumulation. For most people, this is between 45 and 60.
- Create a decumulation planWork with a fee-only financial adviser to create a year-by-year spending plan that draws down your wealth to zero by your estimated death date. Spend more in your golden years (45-65) and less in your slow-go and no-go years.
- Make the psychological shiftActively practice spending more than you earn after your peak. This requires overcoming decades of savings conditioning. Remind yourself that unspent money equals wasted life energy.
John Arnold planned to stop trading once he made $15 million. But his extraordinary success created an addictive habit of earning. He kept moving the goalpost past $25 million, $100 million, $150 million, until he finally retired at 38 with over $4 billion.
Perkins observed his friend John Arnold, a brilliant hedge fund trader who planned to stop at $15 million but could not break the habit of earning, eventually accumulating over $4 billion. Arnold admitted he worked past the point of optimal utility for his money, demonstrating how inertia and moving goalposts prevent people from ever reaching their peak.
