1. What is Goal SIP with Inflation?

The Goal SIP Calculator with Inflation helps you determine how much you need to invest monthly (SIP) to reach a future financial goal, accounting for inflation that will increase the target amount over time.

2. How Does the Calculator Work?

The calculator uses two main formulas:

\[ \text{Adjusted Goal} = \text{Goal} \times (1 + \text{Inflation})^n \] \[ \text{PMT} = \text{Adjusted Goal} \times \frac{r}{(1 + r)^n - 1} \]

Where:

\( \text{Goal} \) — Current target amount (INR)
\( \text{Inflation} \) — Expected annual inflation rate (decimal)
\( n \) — Time period in years
\( r \) — Monthly expected return rate (decimal)
\( \text{PMT} \) — Monthly SIP amount needed

Explanation: First adjusts the goal for inflation, then calculates the monthly investment needed to reach that inflated amount.

3. Importance of Inflation Adjustment

Details: Inflation erodes purchasing power over time. A goal that seems sufficient today may fall short in the future. This calculator ensures your investments account for this.

4. Using the Calculator

Tips: Enter your current financial goal in INR, expected annual inflation rate (typically 5-7% or 0.05-0.07), time horizon in years, and expected annual return rate (converted to monthly automatically).

5. Frequently Asked Questions (FAQ)

Q1: Why account for inflation in SIP calculations?
A: Inflation reduces purchasing power over time. A ₹10 lakh goal today might require ₹20 lakh in 10 years to have equivalent value.

Q2: What's a reasonable inflation rate to use?
A: Historically 5-7% in India. For long-term goals, 6% is commonly used.

Q3: How does return rate affect the calculation?
A: Higher expected returns reduce required SIP amounts, but be realistic to avoid under-saving.

Q4: Should I adjust SIP amounts periodically?
A: Yes, review annually and adjust for changes in income, goals, and actual inflation/returns.

Q5: Can I use this for multiple goals?
A: Calculate separately for each goal with different time horizons and inflation assumptions.
