Calculating How Long Your Funds Will Last
Our Drawdown Calculator allows you to estimate how long your portfolio will last based on a specified annual drawdown amount. By inputting your desired yearly withdrawal, investment assets, assumed return, and indexation rate, the calculator projects how many years your funds can sustain you.
You can also set an altered drawdown at a specific age to reflect changing financial needs, such as increased healthcare costs or reduced expenses later in life. This feature ensures a more tailored approach to managing your retirement funds and helps you plan confidently for the future.
Calculating a Sustainable Drawdown Rate
The calculator can also determine the annual drawdown needed to ensure your portfolio lasts until a specific target age. By factoring in your starting assets, assumed returns, target age, and inflation indexation, it calculates a sustainable withdrawal amount that grows annually to maintain its purchasing power.
This feature helps you plan a balanced retirement income strategy, providing financial security for the duration of your retirement while supporting your current lifestyle needs.
