How to Use SIP Calculator for Mutual Fund Investments
A Systematic Investment Plan (SIP) calculator projects mutual fund growth from monthly investments. In 2025, SIPs grew 25%, with Rs. 500 starting points, per AMFI.
How to use:
1.    Enter Monthly Investment: Say Rs. 5,000.
2.    Set Tenure: E.g., 10 years.
3.    Input Expected Return: Equity funds average 12-15%, per BSE. Use 15% for mid-caps.
4.    Calculate: Formula—Future Value = P × [(1 + r/n)^(n×t) - 1] ÷ (r/n), where P is monthly SIP, r is annual return, n is compounding frequency (12), t is years.
5.    Result: Rs. 5,000 monthly at 15% for 10 years grows to Rs. 13.7 lakh.

Understanding BMI Calculator for Health Awareness
Body Mass Index (BMI) calculators assess health risks by measuring weight relative to height, impacting insurance premiums. Formula: BMI = weight (kg) ÷ height (m²). In 2025, insurers like HDFC ERGO use BMI for health policy pricing—high BMI raises costs 10-15%, per IRDAI.
How to use:
1.    Input Weight: E.g., 70 kg.
2.    Enter Height: E.g., 1.7 m.
3.    Calculate: BMI = 70 ÷ (1.7 × 1.7) = 24.2 (healthy, 18.5-24.9).
4.    Interpret: Below 18.5 (underweight), 25-29.9 (overweight), 30+ (obese).

Retirement Corpus Calculator: Using Inputs Effectively
A retirement corpus calculator estimates savings needed for post-work life. With India’s life expectancy at 75 years and 5.5% inflation (RBI 2025), planning is crucial.
Steps:
1.    Current Monthly Expenses: Say Rs. 40,000 (rent, food, healthcare).
2.    Inflation Rate: 6% (RBI average).
3.    Retirement Age: E.g., 60, current age 35.
4.    Life Expectancy: 85 (25 years post-retirement).
5.    Expected Returns: 6% post-retirement (debt funds).
6.    Calculate: Future expense = Rs. 40,000 × (1 + 0.06)^25 = Rs. 1.72 lakh/month. Annual need = Rs. 20.64 lakh. Corpus = Rs. 20.64 lakh ÷ [(1 – (1 + 0.06)^-25) / 0.06] ≈ Rs. 2.5 crore.
7.    Add Buffer: 10% for emergencies—Rs. 2.75 crore.
A retiree planned Rs. 2 crore, adjusted for inflation. Many underestimate—Rs. 1 crore lasts 12 years. It’s like packing for a long trip—plan for extras. Use niveshkaro.com/calculator for precision. Consult advisor for inputs.

Compound Interest Calculator: Growth Projections Explained
Compound interest calculators show how investments grow with reinvested earnings. Formula: A = P × (1 + r/n)^(n×t), where A is final amount, P is principal, r is annual rate, n is compounding frequency, t is years.
How to use:
1.    Principal: Rs. 1 lakh.
2.    Rate: 12% (equity fund average).
3.    Tenure: 10 years.
4.    Compounding: Annual (n=1).
5.    Result: Rs. 1 lakh × (1 + 0.12)^10 = Rs. 3.1 lakh.
A small-town earner’s Rs. 50,000 grew to Rs. 1.4 lakh in 7 years at 15%. Many expect linear growth—wrong, compounding accelerates. It’s like a snowball rolling—grows bigger over time. Try niveshkaro.com/calculator for projections. Consult advisor for realistic rates.
