CFP retirement savings and income planning
Build retirement income from the spending need backward. Subtract reliable income, calculate the portfolio gap and then evaluate account tax treatment, liquidity and longevity risk. A gross withdrawal is not the same as spendable cash.
The decisions to learn first
Savings account
- What to compare
- Current deduction versus future distribution treatment
- Common mistake
- Assuming every traditional IRA contribution is deductible.
Income gap
- What to compare
- Spending less other stated income
- Common mistake
- Treating gross withdrawals as net spending.
Withdrawal plan
- What to compare
- Taxes, liquidity, timing and market risk
- Common mistake
- Using one universal withdrawal order.
Longevity
- What to compare
- How long resources must support spending
- Common mistake
- Planning only to average life expectancy.
Where this fits in the CFP exam
Retirement Savings and Income Planning is the largest domain at approximately 18%. Its scope includes needs analysis, Social Security and Medicare, retirement plans, distributions, business planning and special needs.
Selected official topic references: F.44, F.51 and F.52.
Practise here: Income gaps, simplified taxable withdrawals and account-treatment distinctions.
Continue your preparation: Social Security, Medicare, employer plan rules, business succession and special-needs planning require separate preparation.
Use consistent cash-flow assumptions
Decide whether the spending target includes taxes. If income sources are quoted gross, either convert them to after-tax values or explicitly model the tax payment as a separate outflow. Avoid mixing both approaches in the same gap.
Traditional and Roth accounts have different tax rules. A traditional IRA distribution is generally taxable except for applicable basis recovery; a qualified Roth distribution is tax-free. The word “qualified” matters. Neither account label by itself resolves every withdrawal restriction.
- 1
Spending
State the annual or monthly after-tax target.
- 2
Other income
Subtract income using the same period and tax basis.
- 3
Portfolio draw
Gross up only the portion assumed fully taxable.
Accumulation and retirement income ask different questions
During accumulation, the planner connects a future goal with current assets, ongoing saving and the assumptions used to project them. During retirement income planning, the focus also includes the amount, timing and tax treatment of distributions, available income sources and the consequences of market losses while spending continues.
A retirement need should identify the period and whether the stated amount is before or after tax and in today’s or future dollars. An inflation adjustment and a tax gross-up solve different problems. Applying one does not silently complete the other.
The wider domain includes employer plans, Social Security and Medicare planning, distribution rules and business succession. A household spending-gap example does not resolve eligibility or plan-specific requirements in those areas. Locate the relevant rule and the case’s dates before using a familiar formula.
Worked example: withdrawals make the order of returns matter
Assume a portfolio starts at $100, withdraws $10 at the end of each year and has no taxes or fees. With returns of +20% then -20%, it ends year one at $110 after the withdrawal and year two at $78. Reverse the returns: after -20% and the first withdrawal it has $70, then after +20% and the second withdrawal it has $74.
The returns and withdrawals are the same, but the ending balances differ. Assets removed after an early loss are no longer available for the later recovery. This simplified sequence illustrates a risk; it does not prescribe a universally safe withdrawal rate.
When solving a case, keep the withdrawal timing explicit. Beginning-of-year withdrawals would produce different numbers. Then connect the result to the actual planning question, such as near-term liquidity, spending flexibility or the resources available outside the portfolio.
Worked example: apply the rule
An original teaching example. All numerical assumptions are stated; this is not a released CFP Board question.
Original worked example
A retired client needs $60,000 after tax annually and has $42,000 of other after-tax income. Assume withdrawals are fully taxable at a flat 20% rate with no other effects. What gross withdrawal fills the gap?
Illustrative values · common scale from zero to $22,500
- Gross withdrawal
- $22,500
- Tax at the assumed 20%
- $4,500
- Net cash for spending
- $18,000
- 1After-tax gap = $60,000 - $42,000 = $18,000.
- 2Each withdrawn dollar supplies $0.80 after tax.
- 3Gross withdrawal = $18,000 ÷ 0.80 = $22,500.
$22,500 gross, leaving $18,000 after the assumed tax.
Watch for: Multiplying the gap by 1.20. That produces only $17,280 after tax, not $18,000.
Change one fact: can you still solve it?
Attempt this original variation before revealing the answer. Explain which assumption changed and why it matters.
Try it
The annual after-tax gap is $18,000. A fully taxable withdrawal of $21,600 is proposed at an assumed flat 20% tax rate. Does it cover the gap?
Reveal answer and reasoning
No. It provides $17,280 after tax, leaving a $720 shortfall.
Verify the proposal by multiplying $21,600 by 0.80. Grossing up requires division by 0.80, giving $22,500; adding 20% to the net need uses the wrong base.
Questions about this topic
Should a client always spend taxable accounts first?
No. Account restrictions, rates, benefit interactions, liquidity and estate goals can change the comparison. The correct sequence depends on the stated facts.

Notes
- * Gross cash and spendable cash differ: Original example: $22,500 less $4,500 leaves $18,000. This simplified flat tax assumption is not a forecast of an individual tax bill. ↩ Return to content
