EMI = [P × r × (1+r)^n] / [(1+r)^n – 1] — where P is principal, r is monthly rate, n is months.
SIP investing via mutual funds has averaged 12-15% annual returns in Indian equity markets (long-term).
FD rates vary from 5-8% across Indian banks — compare using our FD calculator before locking in.
GST has 5 slabs (0%, 5%, 12%, 18%, 28%) — knowing the correct rate prevents compliance issues.

India's financial landscape offers unique tools for wealth building — from SIPs and fixed deposits to tax-saving instruments under Section 80C. This guide covers EMI calculations, SIP growth projections, FD comparisons, and GST compliance using RBI and SEBI guidelines — paired with our free EMI calculator.

🏦

EMI Planning for Loans

EMI (Equated Monthly Installment) is the fixed monthly payment for loans — home, car, personal, or education. The EMI depends on principal amount, interest rate, and tenure. Longer tenure means lower EMI but more total interest paid. Compare options with our EMI calculator. Check current home loan rates from RBI's benchmark rates.

📈

SIP Investing in Mutual Funds

SIP is the most popular investment method in India, with over ₹20,000 crore monthly inflows (2025 data). Start with as little as ₹500/month. Choose from equity, debt, or hybrid funds registered with AMFI. Project your returns with our SIP calculator.

🏧

Fixed Deposits: Safe Returns

FDs offer guaranteed returns at a fixed rate for a set tenure (7 days to 10 years). Senior citizens get 0.25-0.50% extra. Tax-saving FDs (5-year lock-in) qualify under Section 80C (up to ₹1.5 lakh deduction). Compare FD rates across banks with our FD calculator.

🧾

GST Calculation & Compliance

Goods and Services Tax (GST) replaced multiple indirect taxes in India in 2017. Businesses above ₹20 lakh turnover must register. Input Tax Credit (ITC) allows claiming GST paid on purchases. Use our GST calculator for quick inclusive/exclusive calculations across all slabs.

Frequently Asked Questions

How is EMI calculated?

EMI (Equated Monthly Installment) uses the formula: EMI = [P × r × (1+r)^n] / [(1+r)^n – 1]. P is the loan principal, r is the monthly interest rate (annual rate / 12), and n is the number of monthly installments. Our EMI calculator handles this instantly.

What is SIP and how does it work?

SIP (Systematic Investment Plan) allows you to invest a fixed amount regularly in mutual funds. It leverages rupee cost averaging — buying more units when markets are low and fewer when high — reducing timing risk over time.

Are FD returns taxable in India?

Yes, FD interest income is fully taxable per your income tax slab. Banks deduct TDS at 10% if interest exceeds ₹40,000/year (₹50,000 for senior citizens). Declare FD interest under "Income from Other Sources" in ITR.

How do I calculate GST?

GST amount = Price × GST rate. For inclusive pricing: GST = Price – [Price × 100 / (100 + GST rate)]. India has 5 GST slabs: 0%, 5%, 12%, 18%, and 28%. Use our GST calculator to compute for any slab.
