Advanced RMD Calculator
Calculate Required Minimum Distributions (RMDs) across multiple retirement accounts. Analyze withdrawals, taxes, investment growth, and inflation impact to understand how your retirement funds evolve over time.
Formulas Used
- RMD Calculation:
- RMD = Account Balance / Life Expectancy Factor
- Investment Growth:
- Growth = Balance × Return Rate
- Balance Update:
- Balance = Previous Balance + Growth + Contributions − RMD
- Tax on RMD:
- Tax = RMD × Tax Rate
- Real Balance (Inflation Adjusted):
- Real Balance = Balance / (1 + Inflation)^Years
- Annual Percentage Yield (APY):
- APY = (1 + r/12)12 − 1
- Total RMDs:
- Sum of all yearly RMD withdrawals
- After-Tax RMDs:
- After-Tax = RMD × (1 − Tax Rate)
