Compare your expected return against RupeeCase systematic strategies (21% CAGR benchmark). ### What is SIP? A Systematic Investment Plan lets you invest a fixed amount monthly into mutual funds or stocks. Instead of timing the market, you invest consistently, this is called **rupee cost averaging**. When prices drop, you buy more units; when they rise, you buy fewer. Over time, this averages your cost basis. ### The Formula `FV = SIP × ((1+r)^n − 1) / r + Corpus × (1+r)^n` Where r = monthly return rate (annual rate converted), n = total months. The first term is the future value of your SIP stream; the second is your existing corpus compounding. Monthly SIP Existing Corpus Expected Return Investment Period ### Pro Tips * Start early, even ₹5,000/month grows to ₹1 Cr+ in 25 years at 15%. * Increase SIP with salary hikes (see Step-Up SIP below). * Don’t stop SIP during market dips, that’s when you buy cheap units.

A 10% step-up can generate 40 to 60% more wealth over 20 years. ### Why Step-Up? Most people’s income grows 8 to 15% annually. If your SIP stays flat, you’re investing a smaller percentage of income each year. Step-Up SIP increases your investment annually, matching income growth and accelerating wealth creation. ### The Impact Year 1: ₹10K/month. Year 2: ₹11K (at 10% step-up). Year 3: ₹12.1K. Over 20 years, the step-up version invests significantly more, and each extra rupee compounds for the remaining years. Monthly SIP Annual Step-Up Existing Corpus Expected Return Investment Period ### Pro Tips * Match step-up to expected salary growth (8 to 12% for most salaried Indians). * Even 5% step-up makes a massive difference over 15+ years. * Review and increase every April when increments come through.

Find the monthly SIP required starting today. ### Key Concepts Inflation erodes purchasing power, ₹50K/month today equals ₹1.6L/month in 20 years at 6% inflation. Post-retirement, a conservative 8% return (debt + equity mix) is assumed. The calculator uses the present value of annuity formula. ### The 4% Rule Withdraw 4% of your corpus annually. If your corpus is ₹3 Cr, you can spend ₹12L/year (₹1L/month). This rule originated from US research (the Trinity Study) but works as a conservative guide for India too. Current Age Retirement Age Monthly Expenses (today) Current Savings Inflation Expected Return (pre-retire) Life Expectancy ### Pro Tips * Start retirement planning in your 20s, compounding rewards the early bird. * Account for healthcare costs separately (healthcare inflation runs 10 to 12% in India). * NPS + PPF can complement equity returns for the retirement corpus.

Calculate your FIRE number using the 25x rule and compare three investment scenarios. ### The 25x Rule Your FIRE number = Annual Expenses × 25 (based on 4% safe withdrawal rate). If you spend ₹6L/year, you need ₹1.5 Cr. But don’t forget inflation, expenses at FIRE age will be much higher than today. ### Three Scenarios This calculator compares growth at **21%** (RupeeCase systematic), **14%** (Nifty 50 index), and **7%** (Fixed Deposit) to show how strategy choice dramatically affects your FIRE timeline and passive income. Monthly SIP Current Age FIRE Target Age Current Corpus Monthly Expenses Inflation ### Pro Tips * Cut expenses AND increase income for the fastest path to FIRE. * Healthcare is the biggest wildcard post-FIRE, budget for it separately. * Consider Lean FIRE (basic expenses only) vs Fat FIRE (comfortable lifestyle). * In India, rental income can serve as a passive income pillar alongside portfolio returns.

Includes an affordability check against your income. ### Goal-Based Investing Every financial goal needs a plan: a target amount, a timeline, and a monthly commitment. This calculator works backwards from your goal to find the SIP needed, accounting for existing savings that will compound. ### Affordability Check If the required SIP exceeds 30% of your income, consider extending the timeline or starting smaller. Under 20% is comfortable. The calculator shows SIP as a percentage of income and colour-codes it. Goal Amount Years to Goal Expected Return Existing Savings Monthly Income ### Pro Tips * Break large goals into smaller milestones for motivation. * Use separate SIPs for separate goals, don’t mix them. * Equity for 5+ year goals, debt/hybrid for shorter horizons.

Applies to listed equities and equity-oriented mutual funds. ### Tax-Loss Harvesting You can book losses to offset gains. If you have ₹2L LTCG and ₹75K LTCL, net taxable LTCG = ₹1.25L, which falls within the exemption. Zero tax. Review your portfolio in March for harvesting opportunities. Buy Price (per unit) Sell Price (per unit) Quantity Holding Period ### Pro Tips * Hold winners past 12 months when possible to get LTCG rates. * Use the ₹1.25L LTCG exemption every year, don’t let it lapse. * Surcharge and cess are additional (not included here), consult a CA for exact liability.

The annual fee charged by mutual funds, expressed as a % of assets. A 1.5% ER means ₹1,500/year for every ₹1L invested. Direct plans have 0.5 to 1% lower ERs than regular plans. ### The Compounding Drag A fund earning 12% gross with 1.5% ER gives 10.5% net. Over 20 years, ₹10L at 12% = ₹96.5L, but at 10.5% = ₹73.7L. That’s **₹22.8L lost to fees alone**. Investment Amount Fund A Expense Ratio Fund B Expense Ratio Gross Return (both funds) Investment Period ### Pro Tips * Always choose Direct plans (available on AMC websites, Coin, Kuvera, MFCentral). * Index funds have the lowest ERs: 0.1 to 0.3%. * Compare ERs before investing, even 0.3% difference matters over decades.

Compare both approaches over your chosen holding period. ### When Lump Sum Wins In consistently rising markets, investing everything immediately gives maximum time in the market. Academic research (Vanguard, 2012) shows lump sum outperforms SIP ~67% of the time. “Time in market beats timing the market.” ### When SIP Wins In volatile or declining markets, SIP averages your cost basis. If markets drop 20% then recover, SIP buys more units at lower prices. For uncertain times, a 50/50 split (half lump sum + half SIP) can be a pragmatic compromise. Total Amount Expected Return SIP Spread Period Total Holding Period ### Pro Tips * For inheritance or bonus: consider 50% lump sum + 50% via 6 to 12 month SIP. * For regular salary income, SIP is the natural choice. * Don’t let perfect be the enemy of good, invest, don’t wait.

A wake-up call for anyone keeping money in savings accounts. ### What is Inflation? The gradual increase in prices over time. India’s long-term CPI inflation averages 5 to 7%. This means ₹1L today buys only ₹31K worth of goods in 20 years at 6% inflation. ### India-Specific Food inflation can be higher than headline CPI. Healthcare inflation runs at 10 to 12%. Education inflation is 8 to 10%. Real estate varies by city. Plan for **category-specific inflation**, not just the CPI number. Amount Today Inflation Rate Years Ahead ### Pro Tips * Never keep large sums in savings accounts (3.5% < inflation = guaranteed loss). * Equity is the only asset class that consistently beats inflation over long periods. * Real estate rent typically grows with inflation, factor that into retirement planning. Related: [Path 7: Inflation →](/learn/path-7/module-7-3-inflation-types-measurement-investment-impact.html) Quick Tool ## Rule of 72 The quickest mental math trick in investing: divide 72 by the annual return to estimate doubling time. Works for returns, inflation, and debt. ### How It Works 72 ÷ Annual Return = Years to Double. At 12%, money doubles in ~6 years. At 8%, in ~9 years. It’s an approximation of `ln(2)/ln(1+r)`, most accurate for rates between 6 to 20%. ### Beyond Investing Works for inflation too: at 6% inflation, prices double every 12 years. For debt: at 18% credit card interest, your debt doubles in 4 years. Use **Rule of 114** for tripling, **Rule of 144** for quadrupling. Annual Return Starting Amount ### Pro Tips * FD at 7% doubles in 10.3 yrs. Nifty at 14% in 5.1 yrs. RupeeCase at 21% in 3.4 yrs. * Over 30 years: that’s 3 doublings vs 6 vs 9, the difference is astronomical. * Use it at dinner parties to impress people (or not).
