How the SIP Calculator works
Estimate the future value, contributions and growth of a monthly systematic investment plan. Enter the requested values in the units shown. The result is an estimate where measurements, rounding, or local conventions can affect the outcome.
Formula
Future value = monthly contribution × (((1 + monthly return)^number of months − 1) ÷ monthly return); contributions are modeled at each month end.
Worked example
A ₹10,000 month-end SIP earning an assumed 12% annual nominal return for 10 years invests ₹12,00,000; the monthly compounding estimate is about ₹23.0 lakh.
Understanding Systematic Investment Plans (SIP)
A Systematic Investment Plan (SIP) is a disciplined investment approach allowing investors to contribute fixed sums regularly into mutual funds or investment portfolios. Rather than timing volatile markets, SIP harnesses the mathematical benefits of rupee-cost averaging and compounding over long horizons.
SIP Calculation Formula & Mathematics
The standard SIP maturity formula calculates future value assuming regular compounding at each payment interval:
Where:
- M = Future accumulated maturity amount
- P = Periodic monthly investment installment
- i = Monthly interest rate (annual return rate ÷ 12 ÷ 100)
- n = Total number of monthly installments (years × 12)
Step-by-Step Worked SIP Example
Suppose you commit ₹10,000 per month for 10 years (120 installments) with an expected annual return of 12%:
| Metric | Calculation Breakdown | Value |
|---|---|---|
| Total Invested | ₹10,000 × 120 months | ₹12,00,000 |
| Monthly Rate (i) | 12% ÷ 12 months | 1.0% (0.01) |
| Compounding Factor | (1.01)120 | 3.300387 |
| Estimated Wealth Gain | Future Value − Invested Principal | ₹11,00,386 |
| Total Maturity (M) | ₹10,000 × [(3.300387 − 1) ÷ 0.01] × 1.01 | ₹23,00,386 |
Step-up SIP vs Regular SIP
A step-up (top-up) SIP automatically increases monthly contributions by a chosen percentage or fixed amount each year, matching your annual salary increments. For instance, stepping up a ₹10,000 SIP by 10% annually over 10 years increases wealth accumulation from ~₹23 lakh to over ~₹35 lakh.
Practical Use Cases & Investment Goals
- Retirement Corpus: Accumulating retirement wealth over 20–30 years through index and diversified equity funds.
- Higher Education Funding: Funding college tuition fees due 10 to 15 years in the future.
- Home Down Payment: Building savings over 5 to 7 years with moderate risk balance.
Risks, Assumptions and Limitations
This calculator provides an illustration based on constant annualized compounding. Mutual fund returns are market-linked and fluctuate due to economic cycles, sector movements, and asset allocations. Returns are not guaranteed, and exit loads, expense ratios, and capital gains taxes (LTCG / STCG) will affect final net realized yields.
Investment calculator FAQs
Are projected returns guaranteed?
No. The result applies your assumed rate consistently for illustration; real investment values fluctuate, and charges, taxes and timing can change the outcome.
Does the estimate include taxes and fees?
Only when a field explicitly asks for a cost. Review current product terms and tax rules before investing.
Frequently Asked Questions
How accurate are the results provided by the SIP Calculator?
The calculation applies exact mathematical formulas to the inputs you submit. The precision of the resulting figure depends on the accuracy of your source measurements and the consistency of the chosen units.
Are my inputs saved or transmitted to a server?
No. BMICALCI operates 100% clientside within your web browser. Your figures, measurements, dates, or financial assumptions are never recorded, uploaded, or shared across any server.
Can I switch between metric and imperial measurement units?
Calculators that handle multiple dimensional systems provide dedicated unit dropdowns or label conversions beside the inputs. When units are fixed, simply convert your raw values into the designated units before computing.
Does this calculator replace certified professional guidance?
No. BMICALCI utilities provide instant reference calculations and educational estimations. For licensed financial planning, certified architectural construction, legal deadlines, or medical diagnoses, always verify figures with accredited domain professionals.
