What Is an SWP Calculator?

An SWP Calculator calculates how much money you can withdraw periodically (monthly, quarterly, or annually) from your investment while keeping the fund invested. It is designed to:

  • Plan retirement withdrawals
  • Maintain portfolio balance over time
  • Avoid depleting funds prematurely
  • Estimate tax impact on withdrawals

The calculator ensures you have a clear understanding of fund sustainability, making retirement and investment planning easier.

Key Factors Considered

  1. Initial Investment Amount – The total amount in your fund or portfolio.
  2. Expected Rate of Return – Annual growth rate of your investments.
  3. Withdrawal Amount – The sum you intend to withdraw periodically.
  4. Withdrawal Frequency – Monthly, quarterly, or yearly.
  5. Investment Horizon – Number of years you plan to continue withdrawals.

SWP Formulas (Plain Text)

1. Future Value of Withdrawals

FV = P × [(1 + r)ⁿ − 1] ÷ r
Where:

  • P = periodic withdrawal amount
  • r = periodic interest rate (annual rate ÷ frequency)
  • n = total number of periods

2. Remaining Portfolio After Withdrawals

Remaining Value = Initial Investment × (1 + r)ⁿ − FV

3. Withdrawal Amount for Fixed Period

P = [Investment × r × (1 + r)ⁿ] ÷ [(1 + r)ⁿ − 1]

  • Helps calculate fixed withdrawal amounts to exhaust funds over a set period.

4. Adjust for Frequency

  • Monthly withdrawal → r = annual rate ÷ 12, n = years × 12
  • Quarterly withdrawal → r = annual rate ÷ 4, n = years × 4
  • Annual withdrawal → r = annual rate ÷ 1, n = years

How to Use the SWP Calculator

Step 1: Enter Initial Investment

  • Input the total amount currently invested in your portfolio or mutual fund.

Step 2: Set Expected Rate of Return

  • Enter the anticipated annual return on investment.

Step 3: Enter Withdrawal Amount or Duration

  • Specify either:
    • Desired periodic withdrawal amount
    • Duration of withdrawals to deplete the fund

Step 4: Select Withdrawal Frequency

  • Choose monthly, quarterly, or annual withdrawals.

Step 5: Calculate

  • Click calculate to get:
    • Withdrawal amount or duration
    • Remaining portfolio value
    • Estimated total withdrawals over the period

Step 6: Analyze Results

  • Adjust withdrawal amount or period for sustainability.
  • Compare scenarios with different return rates for risk assessment.

Example Calculations

Example 1: Monthly Withdrawal

  • Initial Investment = $100,000
  • Expected Annual Return = 6%
  • Period = 10 years
  • Monthly Withdrawal: r = 0.06 ÷ 12 = 0.005, n = 10 × 12 = 120

Withdrawal Amount (P) = [100,000 × 0.005 × (1 + 0.005)¹²⁰] ÷ [(1 + 0.005)¹²⁰ − 1] ≈ $1,110

Example 2: Fixed Withdrawal for 5 Years

  • Initial Investment = $50,000
  • Annual Return = 8%
  • Period = 5 years
  • Annual Withdrawal: r = 0.08 ÷ 1 = 0.08, n = 5

Withdrawal Amount P = [50,000 × 0.08 × (1 + 0.08)⁵] ÷ [(1 + 0.08)⁵ − 1] ≈ $12,634 per year

Example 3: Remaining Portfolio After Withdrawals

  • Investment = $75,000
  • Monthly Withdrawal = $600
  • Annual Return = 5%
  • Period = 10 years
  • Calculate remaining value using Remaining Value = Initial × (1+r)ⁿ − FV
