SIP Calculator
Estimate the potential future value of your Systematic Investment Plan (SIP) or solve for required targets.
Unique Advantages of NumAtlas SIP Calculator
1. Dynamic Target Solver
Solve backwards for how much you need to invest, how long you should invest, or what returns are needed to reach a custom goal sum.
2. Multi-Option Annual Step-up
Increase your SIP monthly payment by a percentage or a flat currency amount every year. This simulates realistic salary raises.
3. Real-Value Inflation Discount
Understand your actual future purchasing power. Discount your maturity sum by CPI inflation rate to see what it translates to today.
Step-up SIP: Sum(y = 1 to Y) [ P_y * ((1 + i)^12 - 1) / i * (1 + i)^(12 * (Y - y) + 1) ]
- Assumes return rate remains static over the entire investment timeframe.
- No additional fee structures, mutual fund expense ratios, or exit loads are accounted for.
- Taxation (LTCG / STCG on capital gains) is not subtracted from maturity returns.
About the SIP Calculator
A Systematic Investment Plan (SIP) is a disciplined investment strategy that allows individuals to invest a fixed sum of money at regular intervals—typically monthly—into mutual funds or equity portfolios. Unlike lump-sum investments, which require timing the market, SIPs leverage the principles of dollar-cost averaging (or rupee-cost averaging) and compound interest to build long-term wealth. Historically popular in retail investment banking, SIPs reduce risk by purchasing more units when asset prices are low and fewer units when prices are high. This systematic discipline helps investors ignore short-term market volatility and focus on compounding returns. Over an extended duration, the compounding effect grows exponentially, turning small recurring contributions into substantial wealth portfolios. It is an ideal wealth-creation tool for retirement planning, education funding, and achieving long-term financial independence.
Mathematical Formula & Logic
Step-by-Step Example
Estimate the future value of a SIP investing $500 monthly at an expected annual return of 12% for 10 years: 1. Identify the variables: P = 500, Expected annual return = 12%, Tenure = 10 years 2. Compute monthly rate: i = 12 / 12 / 100 = 0.01 3. Compute total months: n = 10 × 12 = 120 months 4. Apply formula: FV = 500 × [ ( (1.01)^120 - 1 ) / 0.01 ] × 1.01 5. Calculate growth multiplier: (1.01)^120 ≈ 3.30039 6. Calculate annuity factor: (3.30039 - 1) / 0.01 = 230.039 7. Apply compounding adjustment: 230.039 × 1.01 ≈ 232.339 8. Calculate final value: FV = 500 × 232.339 ≈ $116,170 9. Estimated returns: $116,170 - ($500 × 120) = $116,170 - $60,000 = $56,170
