Gold vs. SIP vs. FD Calculator

Tri-Asset Class Allocations in India

In the Indian cultural and economic landscape, three core asset classes form the backbone of personal finance:

1. Equity Mutual Fund SIPs: Representing high-yielding corporate business growth, typically compounding at a default benchmark CAGR of 12.0%.
2. Physical Gold: The traditional cultural store of value and inflation hedge, typically compounding at a benchmark CAGR of 8.0%.
3. Fixed Deposits (FDs): The risk-free bank interest benchmark offering high liquidity and security, yielding a default benchmark rate of 6.5%.

This calculator enables you to model a side-by-side comparison of either a monthly SIP or a one-time Lumpsum investment across all three assets to understand the ending wealth gaps.

How to Use the Gold vs. SIP vs. FD Calculator

Compare asset class compounding in a few quick steps:

1. Choose Investment Mode: Select Monthly SIP (for recurring savings) or Lumpsum (for one-time investments).
2. Investment Amount (₹): Enter your monthly SIP amount or your one-time lumpsum principal.
3. Investment Horizon (Years): Choose your investment duration (from 1 to 30 years).
4. Customize Expected Interest Rates: Adjust the sliders for Equity Return (%), Gold Return (%), and FD Return (%) if you wish to model custom rates.
5. View Comparative Ledger: Check the ending corpus, total wealth gained, and the "Wealth Delta Gap" showing the exact cost of conservative investing.

The Comparative Mathematics

To prevent compilation errors, the mathematical formulas are outlined below cleanly without any curly braces:

1. Lumpsum Investment Mode (One-Time Purchase)

For a lumpsum principal (P) invested over T years, the final maturity value (V) for any given compound rate (R%) is:

Maturity Value = Principal * (1 + R / 100) ^ T

• Equity Lumpsum: Uses the custom Equity CAGR rate.
• Physical Gold Lumpsum: Uses the custom Gold CAGR rate.
• Bank FD Lumpsum: Uses the custom FD Interest rate.

2. Systematic Investment Plan (SIP) Mode

For a recurring monthly SIP amount (P) over T years (N months = T * 12), with monthly compounding at an annual rate (R%):

Monthly return rate (r) = R / 1200

Maturity Value = Principal * [ ( (1 + r)^N - 1 ) / r ] * (1 + r)

• Total Capital Saved: Amount * 12 * Years.
• Wealth Delta Gap: The difference between the highest-yielding maturity value and the lowest-yielding maturity value:

Delta Gap = Maximum(Equity, Gold, FD) - Minimum(Equity, Gold, FD)

Side-by-Side Comparison: SIP of ₹10,000 Monthly

The table below compares investing ₹10,000 monthly over a 20-year horizon, with total principal of ₹24,00,000, using broad historical return assumptions for India:

Asset Class	Assumed CAGR	Maturity Value (20 Years)	Wealth Gained	Inflation Beating?	Risk Level
Equity Mutual Fund SIP	12.0%	₹99,91,479	₹75,91,479	Yes (Highly efficient)	High (Market volatility)
Physical Gold SIP	8.0%	₹59,29,472	₹35,29,472	Yes (Modest hedge)	Moderate (Price cycles)
Bank Fixed Deposit (FD)	6.5%	₹48,93,989	₹24,93,989	No (Barely tracks CPI)	Very Low (Safe)

Prudent Checklist for Structuring Your Tri-Asset Allocation

Optimize your wealth accumulation by following these strategic rules of thumb:

• Age-Based Allocation: Use the "100 minus Age" rule. For example, at age 30, keep 70% of your portfolio in Equity, and split the remaining 30% between Gold and Fixed deposits.
• Sovereign Gold Bonds (SGBs): If investing in gold, prioritize SGBs over physical gold or jewelry. SGBs are tax-free on maturity and pay an extra 2.5% p.a. assured simple interest.
• Tax Efficiency Check: Equity capital gains above ₹1.25 Lakhs p.a. are taxed at 12.5% (LTCG). Bank FD interest is taxed as per your individual tax slab every single year, compounding tax drag.
• Liquidity Buffer: Ensure your FD allocation represents at least 6 months of living expenses (emergency fund). Do not touch your Gold or Equity reserves for short-term liquidity needs.
• Rebalance Annually: Once a year, review your asset allocation. If equity has run up and now represents 85% of your portfolio, trim some profits and reinvest them into Gold or FDs to maintain your target risk profile.

Frequently Asked Questions (FAQs)

Why does equity outperform Gold and Fixed Deposits over long horizons?

Fixed deposits and gold are defensive assets that primarily preserve purchasing power. High-quality equity represents ownership in productive businesses that may compound earnings, expand market share, and participate in economic growth over long periods.

Will every stock compound like Wipro or Infosys?

No. Wipro and Infosys represent elite, world-class performers that experienced rapid industry-wide tailwinds (the global IT outsourcing boom). Many companies fail or deliver poor returns. Diversified equity mutual funds or index funds are recommended for balanced risk.

Is Gold really a safe investment?

Yes, gold has been a universally trusted store of value for thousands of years. It shares an inverse relationship with equity; during recessions, stock market crashes, or geopolitical conflicts, gold prices typically rally as investors seek safe havens.

How is FD interest taxed in India?

Fixed Deposit interest is fully taxable under your normal income tax slab rates. If you are in the 30% tax bracket, a 7% FD interest rate yields an actual post-tax return of only 4.9%, which fails to beat the standard 6% inflation rate.
