Start with the decision

How much may I want in cash, steadier investments, and long-term investments?

A retirement bucket strategy separates near-term withdrawals from money intended for later years. This calculator carries savings from your current age to retirement, creates opening cash, steadier, and long-term segments, and then shows every modeled withdrawal, refill, and ending balance through the age you select.

01

How to read it

  • The portfolio spending gap is the amount investments—not gross lifestyle spending—must fund each year.
  • A larger cash bucket may reduce near-term market dependence but also leaves less capital exposed to long-term growth.
  • The refill plan matters as much as the opening allocation; specify when gains are harvested and what happens after poor markets.
02

What could change the answer

  • Security-level investment recommendations or guaranteed returns
  • Account-by-account tax sequencing, required minimum distributions, or Roth conversions
  • Irregular expenses, long-term-care costs, and changes in pension or Social Security income unless entered
  • A complete probability-of-success or Monte Carlo retirement analysis
03

What to take forward

Ask which expenses are recurring, which are one-time, and how much must be withdrawn before tax to meet the after-tax spending need.

Transparent method

How the estimate works

See how the estimate is calculated

Grow today’s portfolio to the entered retirement age using the long-term return after fees, adding the entered savings at each pre-retirement year-end.

Subtract dependable income from retirement spending, adjust that gap for inflation, and reserve the selected opening years in cash and steadier investments before assigning the remainder to long-term investments.

Apply the three net return assumptions each year, withdraw from cash first, move steadier money forward, and use only modeled positive long-term gains to refill the steadier segment.

Common questions

Frequently asked questions

What does a 3 bucket strategy calculator show?

It shows how a near-term cash reserve, a steadier middle bucket, and longer-term growth assets may work together under the spending, return, inflation, and refill assumptions you enter. It is not a probability-of-success forecast.

What is a three-bucket retirement strategy?

It is a retirement-income framework that separates near-term spending reserves, intermediate stability assets, and longer-term growth assets. The labels do not determine the investments; the time horizon and refill rules do.

How many years should be held in the cash bucket?

There is no universal answer. The appropriate reserve depends on dependable income, withdrawal flexibility, taxes, market risk, large planned expenses, and how the other buckets will replenish cash.

Does a bucket strategy eliminate sequence-of-returns risk?

No. It can make near-term spending less dependent on selling growth assets during a decline, but the entire portfolio still faces return, inflation, longevity, and behavior risk.

Is the bucket strategy different from asset allocation?

Usually it is a way of organizing and communicating an asset allocation. The portfolio still needs a coherent overall risk level, tax location, rebalancing policy, and withdrawal process.
