Understanding Retirement Sustainability
Retirement sustainability depends on three main factors:
1. Savings Amount
The more you save, the longer your money lasts.
2. Spending Habits
Lower monthly expenses significantly increase retirement duration.
3. Investment Returns
Higher returns help your savings grow while you withdraw money.
Safe Withdrawal Strategy
Financial experts often recommend withdrawing 3% to 4% annually from retirement savings.
This helps ensure:
- Long-term stability
- Protection against market downturns
- Sustainable income flow
This calculator helps you test whether your current plan aligns with safe withdrawal principles.
