Calculating your final value is straightforward once you know the SWP formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the SWP Calculator.

What is SWP?

The SWP calculation tells you your final value from a few simple inputs. The figure you are solving for here is the final value, expressed in INR.

The SWP formula

This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:

  • Total investment — a money amount. Example: ₹10,00,000.
  • Monthly withdrawal — a money amount. Example: ₹10,000.
  • Expected return (p.a.) — a percentage, such as an annual rate. Example: 8%.
  • Time period — a value you set on the slider. Example: 5 years.

How to calculate it step by step

  • Write down the total investment (for example, ₹10,00,000).
  • Write down the monthly withdrawal (for example, ₹10,000).
  • Write down the expected return (p.a.) (for example, 8%).
  • Note the time period (for example, 5 years).
  • Apply the formula above to get your final value.
  • Double-check the result with the SWP Calculator.

Worked examples

Example 1

Input / OutputValue
Total investment₹10,00,000
Monthly withdrawal₹10,000
Expected return (p.a.)8%
Time period5 years
Final value₹7,55,077
Total withdrawn₹6,00,000
Amount invested₹10,00,000

With total investment of ₹10,00,000, monthly withdrawal of ₹10,000, expected return (p.a.) of 8% and time period of 5 years, the final value works out to ₹7,55,077.

Example 2

With total investment of ₹20,00,000, monthly withdrawal of ₹10,000, expected return (p.a.) of 8% and time period of 5 years, the final value works out to ₹22,44,923.

ResultValue
Final value₹22,44,923
Total withdrawn₹6,00,000
Amount invested₹20,00,000

Example 3

With total investment of ₹5,00,000, monthly withdrawal of ₹10,000, expected return (p.a.) of 8% and time period of 5 years, the final value works out to ₹10,154.

ResultValue
Final value₹10,154
Total withdrawn₹6,00,000
Amount invested₹5,00,000

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.
  • Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).

Prefer not to do the maths by hand? — the SWP Calculator does it instantly, for free, with the formula and a worked example built in.
