Can cutting $500 a month make a retirement plan more resilient?
Linda is a fictional 62-year-old retiree whose original spending plan is vulnerable to weak markets. She wants to see whether reducing first-year spending from $58,000 to $52,000 materially changes the result.

Linda's starting plan
| Input | Fictional assumption |
|---|---|
| Projection ages | 62 through 95 |
| Traditional IRA | $450,000 |
| Roth IRA | $40,000 |
| Taxable savings | $35,000 |
| Original first-year spending | $58,000 |
| Alternative first-year spending | $52,000 |
| Social Security | $2,600 per month at 65, entered in 2026 dollars |
| Filing status and state | Head of Household, Oregon |
| Portfolio | Balanced |
| Market and inflation | Lower Long-Term Return; 2.5% inflation |
Both versions claim Social Security at 65, use no Roth conversion, include healthcare in planned spending, and hold every assumption except spending constant.
One lower-return projection
| Result | $58,000 spending | $52,000 spending |
|---|---|---|
| Inflation-adjusted balance at age 80 | $0 | $194,992 |
| First age with unfunded spending | 80 | 91 |
| Age-95 balance | $0 | $0 |
| Estimated taxes through age 95 | $99,544 | $99,119 |
On the deterministic path, a $6,000 reduction in first-year spending delays the first unfunded need by 11 years. Taxes barely change; the improvement comes primarily from withdrawing less money and leaving more invested.
Results across 1,000 modeled futures
| Modeled risk result | $58,000 spending | $52,000 spending |
|---|---|---|
| Spending covered through age 80 | 51.4% | 82.0% |
| Spending covered through age 95 | 14.8% | 44.4% |
| Middle age-80 balance, inflation-adjusted | $5,618 | $208,549 |
| Cautious age-80 balance | $0 | $43,843 |
| Middle first-shortfall age when one occurs | 79 | 84 |
The lower-spending plan covers spending through age 80 in 82.0% of modeled futures, compared with 51.4% for the original plan. Success through age 95 rises from 14.8% to 44.4%. That is a large improvement, but more than half of modeled futures still experience a shortfall by 95.
These are modeled probabilities of success, not real-world odds or guarantees. They apply only to these fictional inputs and the planner's selected historical-sequence, return, and inflation assumptions.
What Linda could test next
- Separate essential spending from travel, gifts, and other flexible expenses.
- Test a smaller reduction that may be easier to maintain and a larger reduction for difficult years.
- Compare claiming Social Security earlier with the larger age-65 benefit.
- Model part-time income or a later retirement with an explicitly estimated starting balance.
- Test a longer lifetime and higher inflation rather than relying on one endpoint.
- Review housing and healthcare assumptions, which may not rise at the same rate as general spending.
The current planner treats each spending level as a separate inflation-adjusted plan. It does not automatically detect a market decline and apply guardrail spending rules. Users should model a lower spending policy explicitly and decide which expenses could realistically change.
Recreate the study
- Open the planner and enter the fictional starting assumptions shown above.
- Enter the age-specific Social Security estimates, including $2,600 per month at age 65.
- Select the 65 · No Roth row and record the deterministic results.
- Run Retirement Risk Analysis and record success through ages 80 and 95.
- Change Annual Spending from $58,000 to $52,000, then compare the same row and rerun Risk Analysis.
