Planning Assumptions
These planning assumptions form the mathematical basis for compounding, inflation drag, and depletion analysis. Modify them below to stress-test your plan.
The average annual investment return rate expected during your working years.
7.0%0.0%15.0%
%
Explanation: The average annual investment return rate expected during your working years.
Impact: Higher pre-retirement returns exponentially boost your nest egg before retirement.
The average annual investment return rate expected in retirement (typically more conservative).
5.0%0.0%15.0%
%
Explanation: The average annual investment return rate expected in retirement (typically more conservative).
Impact: Higher post-retirement returns reduce the size of the starting nest egg required to sustain spending.
The average long-term inflation rate (CPI). Historical average is ~2.5% - 3%.
2.5%0.0%10.0%
%
Explanation: The average long-term inflation rate (CPI). Historical average is ~2.5% - 3%.
Impact: Higher inflation increases future spending needs, forcing a much larger required nest egg.
Your expected average annual career raise rate.
3.0%0.0%15.0%
%
Explanation: Your expected average annual career raise rate.
Impact: Higher salary growth increases future monthly additions and employer 401(k) matching.
The initial percentage of the portfolio drawn down in year one of retirement (e.g. Bengen 4% Rule).
4.0%0.1%15.0%
%
Explanation: The initial percentage of the portfolio drawn down in year one of retirement (e.g. Bengen 4% Rule).
Impact: Lower rates (3% - 4%) protect against early depletion, while higher rates (>5%) raise depletion risk.
The age you want to ensure your portfolio lasts until.

Explanation: The age you want to ensure your portfolio lasts until.
Impact: Longer planning horizons require a significantly larger nest egg to support more years of drawdown.

Retirement Risk Framework
A dynamic risk analysis evaluated against your current timeline, inflation rates, and cash-flow specifications:
Inflation RiskModerate Severity
Inflation at 2.5% reduces purchasing power. A $60,000 budget will feel like $32,363.44 in 25 years.
Mitigation StrategyAllocate a portion of your portfolio to inflation-resistant assets such as equities, real estate, or TIPS.
Longevity RiskLow Severity
Your portfolio is projected to last past your life expectancy of 90.
Mitigation StrategyDelay Social Security benefits to age 70, consider a single-premium immediate annuity (SPIA), or lower withdrawal rate.
Sequence of Returns RiskModerate Severity
A pre-retirement return of 7% dropping to 5% post-retirement exposes you to cash-flow sensitivity if a market drop occurs early.
Mitigation StrategyMaintain a 1-2 year cash buffer or bond ladder at retirement to avoid liquidating equities in a bear market.
Spending RiskLow Severity
Your chosen withdrawal rate of 4% exceeds the historical 4% safe threshold, raising depletion risk.
Mitigation StrategyImplement dynamic spending rules, such as guardrails, to reduce withdrawals during poor market years.
Early Retirement RiskLow Severity
Retiring at age 65 provides a standard decumulation timeline.
Mitigation StrategyEstablish a bridge fund using taxable brokerage accounts or Roth IRA contributions to fund expenses pre-age 59.5.

Read Full Guide →What is a retirement shortfall?
A shortfall occurs when your projected savings at retirement age are lower than the target nest egg needed to sustain your desired annual withdrawals through your retirement years.
How does inflation affect my retirement plan?
Inflation increases the cost of goods over time. This tool adjusts your desired retirement spending upward by the inflation rate each year, so your estimated future withdrawals maintain the same purchasing power.
What is the standard safe withdrawal rate?
The historical benchmark is the 4% rule (derived from the Trinity Study), which suggests you can withdraw 4% of your initial retirement portfolio value in the first year and adjust for inflation thereafter with a very low risk of running out of money.
