Compare growing contributions with retirement withdrawals
Enter whole-number ages, current assets and a monthly contribution. Contributions can increase or decrease annually at the specified rate. Investment returns are effective annual assumptions converted to monthly rates. They are not historical averages or expected returns supplied by Pineify.
Use a consistent inflation basis
All spending and outside-income inputs are in today’s dollars. The gap is inflated to retirement, then once annually during retirement. Nominal account balances are shown in future USD. Calling these nominal balances “real” would be incorrect.
Required assets and funding use identical cash flows
The required amount is the present value, at retirement, of each planned month-end withdrawal. The same rate and inflation schedule drive the forward projection. The current balance is principal; only the difference after subtracting principal and new contributions is pre-retirement investment growth.
Interpret a shortfall carefully
The first month that cannot fund its scheduled withdrawal is reported as a shortfall. A zero balance with no required withdrawal is not a shortfall. A funded result means only that this deterministic scenario works through the selected horizon, not that retirement is secure under variable returns.
Review benefit and planning assumptions
Use a personalized estimate from Social Security. The model assumes outside income begins at retirement and tracks the same inflation rate as spending. It does not calculate claiming benefits, taxes, fees, RMDs or contribution limits. Salary-multiple milestones depend on their provider’s assumptions and are not substitutes for your cash-flow scenario.
