When to use it
Use it to test how retirement age, annual contributions, spending, pension or Social Security income, investment return, and inflation interact. It is useful for identifying which assumption most changes the projected funding gap.

Estimate whether your savings, contributions, and other income can support your desired retirement spending through a target planning age. Adjust assumptions and review a year-by-year portfolio path.
Before retirement, savings grow with your contribution and return assumptions. At retirement, spending, pension, and Social Security are inflated to that year’s dollars. Each retirement year applies growth, then withdraws what other income does not cover.
Returns and inflation are held constant for the entire projection. Contributions are modeled at the end of each pre-retirement year. Pension and Social Security amounts are entered in today’s dollars and inflated annually.
This is a simplified, deterministic model. It does not account for taxes, required minimum distributions, variable spending, market volatility, fees, or changes in government benefits. Results are educational projections, not financial, tax, or investment advice.

Practical guidance
The planner makes a fixed set of assumptions visible and applies them consistently across accumulation and retirement years. Its value is comparing scenarios, not predicting a single future balance.
Use it to test how retirement age, annual contributions, spending, pension or Social Security income, investment return, and inflation interact. It is useful for identifying which assumption most changes the projected funding gap.
Suppose a household has $500,000 saved, contributes $20,000 annually for 10 years, assumes 5% return and 2.5% inflation, then plans $60,000 of today’s annual spending with $30,000 of other income. The model inflates spending and income to retirement dollars and withdraws only the uncovered amount each year.
During accumulation, the balance grows by the assumed return and receives the modeled contribution. During retirement, the prior balance grows, inflation adjusts spending and other income, and the net income gap is withdrawn. The yearly table exposes that sequence.
Constant returns hide sequence-of-returns risk; constant inflation hides spending shocks. The model excludes taxes, fees, required distributions, benefit rule changes, healthcare shocks, and asset allocation. Test conservative cases and consult qualified financial and tax professionals before acting.
