Used only to express the nest egg in today's purchasing power.
How to use this tool
Enter current USD balance, end-of-month contribution, annual return, years and inflation. Return is constant and compounds monthly, unlike an investment path with fluctuating market outcomes.
Results and examples
Contributions combine starting balance and deposits; growth is the projected balance minus that sum. Inflation-adjusted value is another view of the same balance, not a second amount to add.
Worked example
USD 10,000 plus USD 100 monthly for ten years at 0% gives USD 22,000; at zero inflation its purchasing-power value is unchanged.
Limitations
- Pensions, employer matching, tax, fees and withdrawals are excluded.
- Sequence risk and investment-loss paths are not modelled.
