What Is the 12-12-20 SIP Formula?
The 12-12-20 formula is an easy, structured investment rule that helps investors accumulate long-term wealth using mutual fund SIPs (Systematic Investment Plans). Here’s what it stands for:
12% of Monthly Income: Allocate 12% of your income towards SIP investments.
12% Annual Return: Aim to achieve a 12% annual return by choosing high-quality equity mutual funds.
20-Year Investment Horizon: Stick to this strategy for 20 years to see significant compounding growth.
This formula is ideal for salaried individuals and professionals who want a simple, disciplined method to build wealth without the need for complex investment strategies.
How the 12-12-20 SIP Formula Works in Real Life?
Example Scenario 1: ₹12,000 Monthly SIP
Let’s say you earn ₹1,00,000 per month and decide to invest 12% of your income (₹12,000) monthly into a SIP, choosing an equity mutual fund that offers an average 12% annual return.
Using a compound interest SIP calculator:
Monthly SIP: ₹12,000
Duration: 20 years (240 months)
Expected Annual Return: 12%
Final Corpus: ₹1.00–₹1.10 crore
Total Investment: ₹12,000 x 12 x 20 = ₹28.8 lakh
Gains: ₹70+ lakh (approx.)
This is the power of long-term SIP investing — your wealth grows not just from how much you invest, but from the time you stay invested and the compound returns generated over the years.
Why the 12% Annual Return is Achievable (But Not Guaranteed)?
While 12% annual returns may sound optimistic, historical data from Indian equity mutual funds shows that many large-cap, mid-cap, and multi-cap funds have delivered 10–15% CAGR (Compound Annual Growth Rate) over long periods.
For instance:
Nifty 50 TRI: Delivered ~11–12% returns over the past 20 years.
Top-performing equity mutual funds: Some have even outperformed, offering 14–16% returns for long-term SIP investors.
That said, mutual funds are market-linked products, so returns are not fixed or guaranteed. But by maintaining a long-term view and investing in quality funds, a 12% return is a reasonable assumption for projections.
Step-by-Step Guide to Using the 12-12-20 Formula?
Step 1: Know Your Income
Calculate your monthly income and allocate 12% towards SIP. For example, if your take-home salary is ₹50,000, invest ₹6,000/month.
Step 2: Choose the Right Mutual Funds
Pick funds with a strong long-term track record. Look for:
- Minimum 4-star rating from CRISIL or Morningstar
- Consistent 10–15% 5-year returns
- Diversified large-cap or flexi-cap funds
Step 3: Use a SIP Calculator
Visit AMFI India SIP Calculator or any trusted mutual fund app to project your returns.
Step 4: Stay Invested for 20 Years
Don’t panic with market ups and downs. SIP works best when you don’t stop it, especially during market corrections.
Step 5: Review Annually
While you don’t need to change your plan often, review once a year to ensure your fund is performing as expected.
What If You Increase Your SIP Amount Over Time?
If your income grows, you might increase your SIP investments. Let’s say you start at ₹12,000/month and increase your SIP by 10% annually:
Year 1: ₹12,000/month
Year 2: ₹13,200/month
Year 20: ₹74,579/month
Final corpus in this case? Nearly ₹2 crore, nearly double the base-case scenario.
This shows how even small annual increases can significantly boost your final wealth using SIPs and the 12-12-20 approach.
Benefits of the 12-12-20 SIP Rule
Simplicity
The formula is easy to remember — 12% income, 12% return, 20 years.
Encourages Saving Discipline
Allocating a fixed percentage builds good money habits.
Compound Interest at Its Best
You earn returns on both your capital and the gains you’ve already made.
Ideal for Long-Term Goals
Perfect for retirement planning, children’s education, or buying a house in 15–20 years.
Avoids Timing the Market
SIP removes the stress of market volatility — you buy more units when prices are low, and fewer when high.
What Happens If You Start Early vs Late?
Let’s compare two investors:
Investor A starts at age 25, invests ₹12,000/month for 20 years → Gets ₹1.1 crore
Investor B starts at 35, same investment → Gets only ₹36 lakh
Why such a big difference? Because time is the biggest multiplier in SIP. The earlier you start, the less you need to invest and the more wealth you accumulate.
