2% rule for Retirement:

The 2% rule for retirement, or the safe withdrawal rate (SWR), prescribes taking no more than 2% of your retirement nest egg in any given first year, and thereafter increasing that by inflation each year. This extremely conservative strategy emphasizes the sustainability of your savings, with the goal of having them endure through your retirement years.
A more detailed description follows:
Initial Withdrawal:
In your initial year of retirement, find 2% of your overall retirement fund. This is how much you can withdraw safely.
Annual Adjustments:
Every year, raise your amount withdrawn by the inflation rate. This keeps your purchasing power equal as goods and services become more expensive.
The 2% rule is very conservative in nature, meaning that it seeks to avoid outliving your savings as much as possible. It’s a great choice for those who are most risk-averse or for whom retirement is far-off.
Other Things to Consider:
While the 2% rule is a good guideline, we should take your desired lifestyle, healthcare expenses, and other sources of income you might have into account when deciding on your withdrawal plan.
