Accumulation-to-income rails
Contribution climb, retirement transition gate, nominal drawdown, and real-value rail
The projection changes cash-flow direction at retirement instead of extending one accumulation curve through the entire horizon.

How to use
Define both sides of the retirement transition
- Enter current invested assets.
- Use sustainable employee and employer contributions.
- Set a clear retirement date.
- Model withdrawals after contributions stop.
Calculation logic
Retirement is a cash-flow regime change
Accumulation adds two cash sources; retirement reverses the direction with withdrawals.
Real value deflates the final nominal balance across both phases.
Calculation method
Simulate accumulation and income phases with separate cash flows
Contributions and match enter before retirement; withdrawals replace them afterward. Fees reduce the assumed return in both phases.

- Return sequence near retirement.
- Withdrawal taxes and benefits.
- Inflation-sensitive spending.
Transition anatomy
What arrives at retirement and what remains later
Contribution, match, growth, and withdrawals are reported separately.
Retirement-date balance
—Capital available when the income phase begins.
Employer match
—Total modeled employer-funded saving.
Real ending balance
—Final capital expressed in today's money.
Decision takeaway: Use the transition balance to test withdrawal plans before focusing on distant ending value.
Practical applications
Decisions this calculator is designed to support
Mid-career accumulation
A worker contributes for twelve more years before withdrawals begin.
What the result clarifies: The transition gate shows the balance that actually funds retirement.
Employer match change
A worker evaluates the value of a monthly match.
What the result clarifies: Match contribution and market growth remain separate.

Important note
This deterministic model omits taxes, contribution limits, vesting, required distributions, benefit changes, and volatile return sequences.
Retirement Income Growth Projection Calculator FAQ
Do contributions continue after retirement?
No. They stop at the entered transition.
Does withdrawal grow with inflation?
This version keeps the entered nominal monthly withdrawal constant.
Why show real ending value?
It translates future nominal capital into today's purchasing power.
