How to Use a SIP Calculator: Step-by-Step Guide

A Systematic Investment Plan (SIP) is one of the most effective strategies for retail investors to accumulate wealth over time. By investing a consistent sum at regular intervals, you avoid the hazards of market timing while taking advantage of dollar-cost averaging and compounding growth.

You can simulate different monthly deposit amounts, tenures, and expected returns with the free Burnjet SIP Calculator.


What Is a SIP and How Does It Work? #

Instead of requiring a large lump sum upfront, a SIP automates regular contributions (such as $500 or ₹5,000 per month) into an equity fund or portfolio.

  1. Disciplined Habit: Automates monthly savings directly from your earnings.
  2. Dollar-Cost Averaging: When prices drop, your fixed installment buys more units; when prices rise, it buys fewer units, averaging your unit cost down.
  3. Compound Compounding: Early installments have more years to compound than later ones.

The SIP Maturity Formula #

The mathematical equation used to determine the future maturity value of regular SIP contributions is:

M = P imes rac{(1 + i)^n - 1}{i} imes (1 + i)

Where:

  • MM: Final maturity value at the end of the duration
  • PP: Monthly installment amount
  • ii: Periodic monthly rate of return (i = rac{ ext{Annual Rate}}{12 imes 100})
  • nn: Total number of monthly installments (n=extYearsimes12n = ext{Years} imes 12)

Step-by-Step: Using the Burnjet SIP Calculator #

Step 1: Open the Calculator #

Visit Burnjet SIP Calculator.

Step 2: Set the Monthly Investment #

Enter your planned monthly commitment (e.g., ₹5,000 or $500).

Step 3: Enter Expected Return Rate (%) #

Provide an annualized return expectation (e.g., 1212% for broad-market equity index funds).

Step 4: Select Your Time Horizon #

Choose your investment timeline in years (e.g., $15$ years).

Step 5: Evaluate the Wealth Gained vs. Invested Amount #

The calculator dynamically computes your:

  • Total Amount Invested
  • Estimated Wealth Growth (Profit)
  • Total Maturity Value

Example: 15-Year SIP Calculation #

Consider a monthly SIP of ₹5,000 over 15 years with an expected return of 12% per year:

  • Total Months (nn): 15imes12=18015 imes 12 = 180 months
  • Total Capital Invested: ₹5,000 imesimes 180 = ₹9,00,000
  • Estimated Wealth Growth: ₹16,22,880
  • Total Maturity Value: ₹25,22,880

Notice that the earned gains (₹16.22 Lakhs) significantly exceed the original capital invested (₹9 Lakhs) due to continuous compounding over the 15-year horizon.
