What is the 4% rule in retirement planning?

Monte Carlo simulation runs thousands of random market scenarios to show the probability your savings will last through retirement. Financial Toolset uses this method to model how different withdrawal rates affect portfolio survival odds under varying market conditions.

How does inflation affect retirement withdrawals?

Inflation erodes purchasing power over time, meaning a fixed dollar amount buys less each year. Both calculators adjust withdrawals for inflation, but Financial Toolset specifically models estimated inflation rates to provide a realistic view of long-term financial sustainability.

Can I use these calculators if I have irregular income sources in retirement?

These tools assume a fixed portfolio balance and regular withdrawals. Irregular income sources like part-time work or rental income would need to be accounted for separately, as the calculators don't model variable cash flows beyond the specified withdrawal amount.

What's the difference between beginning-of-period and end-of-period withdrawals?

Omni Calculator offers options for withdrawals at the beginning or end of each period, which affects how quickly the balance depletes. This timing difference can meaningfully impact the total number of withdrawals before funds run out.
