Pension COLA and inflation risk
Measure how fixed or partially adjusted pension income may change in purchasing power across a long retirement.
A pension can be dependable in dollars while losing real purchasing power. Separate the essential expenses it covers now from the costs most exposed to inflation.

Build an income purchasing-power table
Show the pension at retirement, ten years later, and twenty years later under low, central, and high inflation assumptions, with the adjustment rule applied.
Read the actual adjustment rule
A pension may be fixed, tied to an index, capped, granted at discretion, or adjusted only under specific conditions. Record the formal rule and whether it applies to the full benefit. Do not describe a payment as inflation protected because it increased once.
Find out when the first adjustment can occur, which index or decision process is used, whether increases are capped, and whether missed inflation can be recovered later. Apply the rule to the actual starting benefit. A plan with a delayed or capped adjustment can behave very differently from inflation even when both rise over time.
Planning lens: Use the formal COLA rule.
Separate nominal and real income
Build a table showing the stated payment and its purchasing power under several inflation paths. Keep the same dollar basis when comparing spending and income. A fixed pension can still be valuable, but more of the inflation job may fall on Social Security, investments, or flexible spending.
Show results in today’s purchasing power and future dollars, but do not mix the two columns. Use the same inflation scenarios for expenses and benefits. The gap is the amount of spending that other income, investments, or adjustments must carry; it is not proof that the pension itself is a poor benefit.
Planning lens: Compare nominal and purchasing power.
Test essential spending first
Compare the pension and other dependable income with housing, food, insurance, healthcare, and taxes. If fixed income covers essentials today, show when higher costs could create a gap. Then decide which portfolio assets or spending adjustments are meant to respond.
Break essentials into categories because inflation does not affect every bill alike. Housing debt may be fixed while insurance, food, utilities, and healthcare change differently. This makes the response practical: a general portfolio reserve may cover broad inflation, while a housing or care decision addresses a concentrated cost.
Planning lens: Stress-test essential costs.
Review the survivor adjustment
Confirm whether the inflation feature continues after the participant's death and how it applies to the survivor percentage. A strong initial survivor amount can still weaken over a long period when the adjustment is limited. Keep the rule with the pension election documents.
Run the survivor calculation from the reduced pension amount, then apply the survivor adjustment rule. Also remove income that ends at the first death. This can reveal a later-life gap that is invisible in the participant’s projection and gives the household time to build a reserve or select a different pension option.

Give inflation risk a separate response
Document the COLA terms, spending covered by the pension, inflation-sensitive gaps, and the assets or adjustments intended to address them.
Connect this decision to your plan
A pension or annuity decision trades liquidity and flexibility for a stream of income, so the household must compare the contract with the full retirement plan. Use the full pensions and annuities in retirement framework to keep this choice connected to the rest of the topic.

Carry the real-income result into the full annuity evaluation framework before comparing a contract with investments.
