SWR Calculator


What Is a Safe Withdrawal Rate Calculator?

A Safe Withdrawal Rate (SWR) Calculator helps investors estimate how much money they can withdraw from their retirement portfolio every year without significantly increasing the risk of running out of money.

The calculator helps answer questions such as:

  • How much monthly income can my investments generate?
  • Is my retirement corpus sufficient?
  • How much can I withdraw safely?
  • How long will my money last?

It is one of the most widely used retirement planning tools globally.


What Is Safe Withdrawal Rate (SWR)?

Safe Withdrawal Rate refers to the percentage of a retirement portfolio that can be withdrawn annually while aiming to preserve the portfolio for the long term.

The most commonly discussed guideline is:

4% Rule

Under this approach:

A retiree withdraws approximately 4% of their portfolio annually.

Example:

Retirement Corpus:
₹5 Crore

Safe Withdrawal Rate:
4%

Annual Income:
₹20 Lakh

Monthly Income:
₹1.67 Lakh


SWR Formula

The basic calculation is:

Example:

Portfolio:
₹3 Crore

Withdrawal Rate:
4%

Annual Withdrawal:
₹12 Lakh

Monthly Withdrawal:
₹1 Lakh


Example SWR Calculation

Retirement Corpus:
₹2 Crore

Withdrawal Rate:
4%

Results:

Annual Withdrawal:
₹8 Lakh

Monthly Withdrawal:
₹66,667

This provides an estimate of sustainable retirement income.
