A fictional retirement-income model with spending gap, withdrawal scenarios, inflation, return-order comparison and dated rule questions.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • An income/spending map with an annual and monthly gap.
  • A one-year withdrawal roll-forward and conditional rate explanation.
  • An inflation-adjusted spending table with category limits.
  • A return-order stress table and sequence-risk explanation.
  • A gross/net withdrawal worksheet and dated rule-verification list.
  • A retirement scenario packet and spending-review policy.

Review and revise

Use these criteria to check your work and choose what to improve.

  • All supplied records reconcile and the decision uses the named case rules.
  • Calculations show units, intermediate values and a second check.
  • Changed-input practice revises the affected result and identifies uncertainty.
  • The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life

This is an original fictional practice case. No account, payment, personal record or outside participation is required. Fictional annual spending $30,000; supplied pension $12,000 and benefit estimate $10,000. Ignore tax and inflation initially.

The idea

Separate income that the case assumes continues from portfolio money that must be withdrawn; all future values are scenarios, not promised benefits.

Map retirement income and a spending gap — worked practice

Separate income that the case assumes continues from portfolio money that must be withdrawn; all future values are scenarios, not promised benefits.

Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Fictional annual spending $30,000; supplied pension $12,000 and benefit estimate $10,000. Ignore tax and inflation initially.

  1. 1. Step 1: List spending and each income source

    List spending and each income source.

    You should see: $30,000 spending; $22,000 combined assumed income.

    Separate income that the case assumes continues from portfolio money that must be withdrawn; all future values are scenarios, not promised benefits.

  2. 2. Step 2: Calculate the annual gap

    Calculate the annual gap.

    You should see: 30000−22000=$8,000.

    Keep this intermediate result so the final decision can be checked.

  3. 3. Step 3: Convert the gap to a monthly planning amount

    Convert the gap to a monthly planning amount.

    You should see: 8000/12≈$666.67.

    Keep this intermediate result so the final decision can be checked.

  4. 4. Step 4: Document source/estimate limits

    Document source/estimate limits.

    You should see: The case assumes both incomes; a real benefit requires current SSA/plan-specific verification, not this exercise.

    Keep this intermediate result so the final decision can be checked.

Now change one thing

Annual spending rises to $33,000. Annual gap?

Your work

What to finish

An income/spending map with an annual and monthly gap.

Common mistake

Watch for this

Treating the supplied pension or benefit amount as a guaranteed personal entitlement.

How can I tell I understand it?

Calculate an annual retirement spending gap from explicitly assumed income on the supplied changed case while preserving the stated rule and checking the final record.
