SIP Calculator

This SIP planning tool supports forward projection and reverse target planning with step-up contributions, inflation adjustment, and scenario sensitivity analysis. Results are estimates, not guaranteed investment outcomes.

Portfolio Insights

  • At a 10-year horizon, corpus formation is currently 51.6% contribution-driven and 48.4% return-driven. Over longer tenures, compounding typically becomes the dominant driver.
  • Return sensitivity: increasing expected return by 1% adds approximately ₹71,708 to projected corpus.
  • Tenure sensitivity: extending your horizon by 5 years (to 15 years total) increases projected corpus to ₹25,22,880— an incremental gain of ₹13,61,185 over the 10-year plan.
  • SIP increase sensitivity: increasing monthly SIP by 10% adds ₹1,16,170.
  • Rule of 72 estimate: at 12.0%, capital may double in 6.0 years.
  • Compounding crossover occurs in Year 7, when estimated annual returns exceed annual SIP contributions.

Asset TypeTypical Long-Term RangeVolatility Note
Savings2% to 4%Low volatility, limited real-return potential.
Debt Funds5% to 7%Moderate volatility; sensitive to interest-rate cycles.
Equity Funds10% to 12%High volatility; long horizon needed to absorb drawdowns.

Historical long-term equity returns vary by market cycle and are not guaranteed.

SIP Calculator Guide

Estimate long-term corpus from monthly investments and expected annual return.

How This Calculator Works

SIP Calculator converts your assumptions into step-by-step projections using standard financial math, helping you compare realistic scenarios before making decisions.

SIP Future Value Formula

FV = SIP × [((1 + i)^n - 1) / i] × (1 + i)

Formula Variables

  • FV: Future value of SIP investments
  • SIP: Monthly investment amount
  • i: Monthly return rate
  • n: Total number of months

Calculation Steps

  1. Enter monthly SIP amount, expected return, and investment tenure.
  2. Tool compounds each contribution for the remaining horizon.
  3. It aggregates all monthly contributions into final corpus projection.
  4. Adjust SIP amount and tenure to achieve target value.

In-Depth Guide

How SIP Compounding Works

A SIP compounds each installment for a different duration: earlier contributions stay invested longer and create a larger share of long-term corpus. This is why consistency and tenure matter as much as return assumptions. The calculator models monthly contribution flow, expected annual return, and tenure to estimate future corpus, contribution share, and return share with transparent math.

Strategic Use & Scenario Planning

Use scenario ranges instead of a single projection: conservative (lower return, higher inflation), base case, and optimistic case. Reverse planning can estimate required SIP for a target corpus, while step-up mode helps model income growth with annual SIP increases. Pair this output with the Compound Interest Calculator for long-horizon compounding validation, the Retirement Calculator for goal adequacy checks, and the Inflation Calculator for real purchasing-power analysis.

Risks & Limitations

SIP projections are estimates, not guaranteed returns. Market volatility, sequence risk, fund selection quality, costs, taxes, and behavioral interruptions can materially change outcomes. Inflation can also reduce real corpus value even when nominal growth appears strong. Use this tool for disciplined planning, periodic reviews, and risk-aware decision making rather than as a certainty forecast.

Summary

This SIP calculator is designed as a financial planning workflow: model expected corpus, stress test assumptions, and refine contributions based on risk tolerance and real-return targets. Better outcomes come from consistent investing, realistic assumptions, and regular course correction.

Frequently Asked Questions

Is SIP better than lump-sum investing?

Both have use cases. SIP is often preferred for regular income earners and helps average purchase cost across market cycles.

Can I increase SIP amount over time?

Yes. Step-up SIP strategies can improve corpus significantly as income grows.

Should I stop SIP during market falls?

Stopping may hurt long-term outcomes. Continuing disciplined contributions often improves unit accumulation during lower prices.

What return should I assume in SIP planning?

Use realistic long-term ranges based on asset mix and keep conservative assumptions for critical goals.

How long should I stay invested?

Longer horizons generally improve outcomes because compounding has more time to work.

Do SIPs guarantee returns?

No. SIPs are a disciplined investing method, but actual returns depend on market performance and fund selection.
