Direct answer: How much do I need to retire?
The real retirement question is not one account balance. It is whether your income sources, withdrawal order, tax plan, Social Security timing, and stress tests can fund your spending through bad markets and a long life.
How Celestice helps
Celestice connects goals, accounts, cash-flow assumptions, tax context, and scenarios in one reviewed workflow. In practice, Celestice helps compare alternatives, preserve assumptions, surface next actions, and route high-impact recommendations through approval instead of leaving the answer in a static planning note.

Retirement planning is usually sold as a single figure: save this much and you are set. It is a comforting idea and a misleading one. A lump-sum target says nothing about how you will turn savings into income, when to claim Social Security, which accounts to draw from first, how taxes reshape every withdrawal, or what happens if markets disappoint early. Retirement is not a one-time report. It is a monitored program — a repeatable operating plan that connects your goals and portfolio to a set of annual actions, and gets reviewed as reality unfolds.
Readiness: the questions a number can't answer
A real retirement review starts with a cluster of linked diagnostics, not a single balance:
- Income gap. The difference between the income you will need and the income your defined sources (Social Security, pensions, annuities) are expected to provide. The portfolio's job is to fill that gap.
- Replacement ratio. What share of your pre-retirement income the plan actually replaces — a more honest readiness signal than a raw account total.
- Depletion risk. The probability your assets run out before you do. This is the number that should keep a plan honest, and it cannot be read off a balance.
Together these tell you not just whether you have "enough," but whether the plan survives a bad sequence of years.
Social Security claiming is a high-stakes decision
When you claim Social Security can swing lifetime benefits by a large margin. Claim early and you lock in a permanently reduced benefit; delay and each year of waiting increases it until age 70. The right answer depends on longevity expectations, other income, tax interaction, and — critically — spousal and survivor effects, because the higher earner's claiming decision sets the survivor benefit for the rest of a spouse's life. A good plan compares claiming ages side by side rather than defaulting to "take it as soon as I can."
Withdrawal sequencing: the order matters as much as the amount
Two retirees with identical balances can end up with very different after-tax outcomes purely from the order in which they draw accounts. Coordinating taxable, tax-deferred, and Roth withdrawals — and blending them to manage each year's taxable income — can extend the life of a portfolio and reduce lifetime taxes. This is where retirement planning connects directly to Roth conversions and tax planning: a low-income year early in retirement may be an opportunity to convert or realize gains at a lower rate, before required minimum distributions push income higher.
Testing the plan against bad luck
Because markets are uncertain, a retirement plan should be stress-tested, not just projected on average. That means running:
- Monte Carlo simulation to see the range of outcomes and the probability the plan holds, not just the median path;
- stress scenarios — a market crash in the first few years, when sequence-of- returns risk is most dangerous;
- expense shocks — a large medical or long-term-care cost late in the plan.
A plan that looks fine on an average-return spreadsheet can fail badly under a poor early sequence. Knowing the probability of success, and where the plan is fragile, is what turns a projection into a decision you can trust.
