Generational Wealth Retirement Calculator — Fund Income Without Touching Principal
When the inheritance toggle is enabled, the retirement engine shifts from a total-depletion model to a principal-preservation model: your portfolio must generate the target income purely from investment returns, leaving the full starting principal intact at death. With $500,000 in current savings and a $90,000/year income target, the projection shows how much total capital is required by retirement so that returns alone—at your assumed 8.5% nominal rate net of 2.5% inflation—cover withdrawals without eroding the base. In practice, this is equivalent to a 6% real withdrawal rate ceiling: the required terminal balance at retirement equals targetAnnualIncome ÷ (annualReturn − inflation). Adjust the return and inflation assumptions to see how sensitive the inheritance floor is to market conditions.
Expert tip: Principal preservation is mechanically achievable but brittle under sequence-of-returns risk. A 25% market decline in the first two years of retirement forces either a drawdown of principal or a withdrawal rate reduction—both of which violate the inheritance constraint. Model a 6% return scenario (pessimistic) alongside the 8.5% base case. If the pessimistic case still preserves principal, your plan is robust. If it does not, a higher retirement savings target or a lower income draw is required before the preservation guarantee holds.

You can safely stop contributing completely today. Your current portfolio will grow on its own to fully fund your retirement by age 65. In fact, you could retire as early as age 50, or age 51 to preserve your principal indefinitely.Portfolio Trajectory
Retirement Planning — Common Questions
Standard retirement advice focuses on reaching a specific age. That is the wrong framework. Financial independence is a state of leverage, not an age, and planning ahead is simply the act of buying back your future time.
The Cost of Delay
Time is the most powerful variable in the compound interest formula. Capital deployed today does the heavy lifting so you don't have to break your back later. Every year you wait forces you to save exponentially more of your active income just to catch up.
Outpacing the Silent Tax
Inflation aggressively steals your purchasing power every year. If historical inflation averages 3 %, a $100,000 cash savings account loses roughly $3,000 of buying power in year one. Over 24 years, that same $100,000 will buy exactly half as much as it does today. This is why this calculator uses Real Return (Growth minus Inflation).
Building Optionality
You aren't just saving to quit working at 65. Reaching financial milestones early gives you absolute leverage to start a business, take a sabbatical, or downshift your career on your own terms.
