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. Opening $100,000; withdraw $10,000 at each year start. Path A returns −20%, then +25%; path B +25%, then −20%. Ignore fees/tax.

The idea

Without withdrawals, multiplication is order-independent; with fixed draws, early losses can leave less capital for later recovery.

Compare the order of returns during withdrawals — worked practice

Without withdrawals, multiplication is order-independent; with fixed draws, early losses can leave less capital for later recovery.

Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Opening $100,000; withdraw $10,000 at each year start. Path A returns −20%, then +25%; path B +25%, then −20%. Ignore fees/tax.

Copy as plain text
  1. 1. Step 1: Calculate A after year 1

    Calculate A after year 1.

    You should see: (100000−10000)×0.8=$72,000.

    Without withdrawals, multiplication is order-independent; with fixed draws, early losses can leave less capital for later recovery.

  2. 2. Step 2: Calculate A after year 2

    Calculate A after year 2.

    You should see: (72000−10000)×1.25=$77,500.

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

  3. 3. Step 3: Calculate B in the opposite order

    Calculate B in the opposite order.

    You should see: Year1 $112,500; year2 (112500−10000)×0.8=$82,000.

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

  4. 4. Step 4: Explain the $4,500 difference

    Explain the $4,500 difference.

    You should see: Same two returns, different order under withdrawals; without withdrawals both paths end $100,000.

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

Now change one thing

Use $5,000 annual start-year withdrawals on path A. End of year 2?

Your work

What to finish

A return-order stress table and sequence-risk explanation.

Common mistake

Watch for this

Assuming identical average returns imply identical balances during withdrawals.

How can I tell I understand it?

Compare two specified return sequences with identical start-year withdrawals on the supplied changed case while preserving the stated rule and checking the final record.
