SWP CALCULATOR

 Planning retirement income is just as important as building retirement wealth. While SIPs help you accumulate money during your working years, a Systematic Withdrawal Plan (SWP) helps you convert that accumulated corpus into a steady, tax-efficient income stream after retirement.

This SWP Calculator is a comprehensive retirement income planning tool that accounts for investment returns, inflation, income tax, withdrawal sustainability, and long-term portfolio health. This detailed guide explains how the calculator works, how to use every input, how to read the results, and how to apply the insights to real-life retirement planning decisions.

A Systematic Withdrawal Plan (SWP) is an investment strategy that allows you to withdraw a fixed amount of money at regular intervals (monthly or annually) from an invested corpus.

Instead of withdrawing your entire investment at once, SWP lets:

• Your remaining corpus stay invested
• Withdrawals happen periodically
• Returns continue compounding on the remaining balance
   

SWPs are commonly used for:

• Retirement income
• Early financial independence (FIRE)
• Passive income generation
• Pension-like cash flow from investments 
• 
  

Retirement is not about accumulating money—it’s about making your money last.

Without proper withdrawal planning, retirees risk:

• Outliving their savings
• Losing purchasing power due to inflation 
• Paying unnecessary taxes
• Running out of money late in life

This SWP calculator helps you answer the most critical retirement question:

“Can my investment sustain my lifestyle for the rest of my life?”

This calculator is more advanced than basic SWP tools and includes real-world retirement variables.

• Monthly withdrawal planning
• Inflation-adjusted income simulation
• Income tax impact calculation
• Retirement age–based planning horizon 
• Sustainability & risk indicator 
• Year-by-year withdrawal table
• Visual portfolio balance chart
• SIP vs SWP comparison built-in
• Multi-currency support 

It is suitable for both beginners and advanced retirement planners.

The SWP Calculator estimates your retirement withdrawals by simulating investment growth, taxes, inflation adjustments, and withdrawal patterns. The calculator uses:

1. Compound growth formula for investment returns
2. Monthly withdrawal calculations with optional annual step-ups
3. Inflation adjustments if you choose real returns
4. Monte Carlo stress testing to evaluate risk in volatile markets
5. Safe withdrawal rate alerts to prevent over-withdrawing
    

By combining these calculations, the calculator shows you year-wise withdrawal tables, final balances, and risk indicators, giving a realistic overview of your retirement sustainability.

1. Select Your Currency
   Choose your preferred currency (INR, USD, EUR, GBP) for all calculations.
2. Enter Your Current Age
   Input your present age to calculate the timeline until retirement.
3. Enter Planned Retirement Age
   Specify when you want to start withdrawals.
4. Set Withdrawal End Age
   This determines the duration of your SWP. For example, if retirement age is 60 and end age is 85, the SWP duration is 25 years.
5. Input Initial Investment
   Enter your retirement corpus or investment fund from which withdrawals will be made.
6. Set Expected Annual Return (%)
   Enter the expected growth rate of your investments. This can be based on historical returns of your portfolio.
7. Step-up Withdrawal (% per year)
   Specify an annual increase in withdrawals to account for inflation or rising living costs. 
8. Monthly Withdrawal (Year 1)
   Enter the amount you wish to withdraw in the first year. The calculator adjusts subsequent withdrawals based on step-up percentage and risk factors.
9. Income Tax on Withdrawal (%)
   Include applicable taxes to calculate net withdrawals and balance.
10. Safe Withdrawal Rate (%)
    The calculator alerts you if the initial withdrawal exceeds this rate to protect your corpus. 
11. Select Real vs Nominal Returns
    • Nominal Returns: Do not adjust for inflation
    • Real Returns: Adjust for inflation to maintain purchasing power 

1. Enter Inflation Rate (%)
   Required if you select real returns to ensure accurate real value calculations.
    

The calculator provides:

1. Final Balance – Estimated corpus left after the withdrawal period
2. Total Withdrawn – Total withdrawals during retirement 
3. Total Tax Paid – Taxes paid on withdrawals 
4. Risk Status – Indicates whether your withdrawals are sustainable or high-risk
    

Year-wise Table:
Shows annual withdrawals, taxes, and end-of-year balances.

Chart:
Visualizes your corpus over the withdrawal period.

Gradually increase withdrawals each year to account for rising living costs. For example, a 5% step-up increases a ₹30,000 monthly withdrawal in Year 1 to ₹31,500 in Year 2.

The SWP Calculator warns if your withdrawal exceeds the recommended SWR to avoid prematurely depleting your funds.

• Nominal: Shows withdrawals without inflation adjustment
• Real: Maintains purchasing power by adjusting withdrawals for inflation 

Simulates multiple market scenarios to show potential worst-case outcomes. Helps you evaluate risk of portfolio depletion over the withdrawal period.

If the balance drops below zero in any scenario, the calculator automatically adjusts withdrawals, showing a realistic safe withdrawal plan.

• Avoid starting with withdrawals above 4–5% of corpus for long-term sustainability 
• Factor in inflation to maintain purchasing power 
• Use step-up withdrawals to keep pace with rising expenses
• Monitor risk status with Monte Carlo simulations 
• Reassess investment returns and withdrawal plans annually

The calculator includes a built-in comparison table.

• Used during earning years 
• Focused on wealth creation
• Money flows into investments
   

• Used after retirement 
• Focused on income generation
• Money flows out of investments

They are two sides of the same financial lifecycle.

• Corpus: ₹1 crore
• Return: 8%
• Withdrawal: ₹30,000/month
• Inflation: 6%
• Tax: 10% 

Result:

• Sustainable income 
• Portfolio survives full retirement
   

• Same corpus
• Withdrawal: ₹50,000/month
• Inflation ON
   

Result:

• Early depletion
• High-risk status
   

Lower withdrawal + lower tax:

• Improved longevity
• Better sustainability
   

This calculator allows you to experiment safely.

Even small reductions dramatically improve longevity.

Some expenses don’t rise equally—plan realistically.

Use tax-efficient funds and strategies.

Avoid overly conservative or aggressive assumptions.

This tool is ideal for:

• Retirees 
• Pre-retirees
• FIRE planners
• Financial advisors
• Long-term investors
• Pension planners

• Ignoring inflation
• Over-withdrawing early 
• Underestimating taxes
• Assuming guaranteed returns 
• Not stress-testing scenarios

This calculator helps expose these risks early.

The SWP Calculator is a powerful tool for retirees and pre-retirees, offering a comprehensive view of withdrawals, taxes, inflation, and risk. By inputting your personal data and using advanced features like step-up withdrawals, safe withdrawal rate warnings, and Monte Carlo stress tests, you can plan a secure and sustainable retirement income strategy.
