An EMI (Equated Monthly Installment) Calculator is a free online tool that helps you calculate the fixed monthly amount you need to pay to repay a loan. It takes into account the loan amount, interest rate, and loan tenure to give you your exact monthly payment.

EMI is calculated using the formula: EMI = P × r × (1+r)^n / ((1+r)^n – 1). Where P = Principal loan amount, r = Monthly interest rate (annual rate divided by 12), n = Number of monthly installments. Our EMI calculator does this calculation instantly for you!

Three main factors affect your EMI: (1) Loan Amount — higher loan means higher EMI, (2) Interest Rate — higher rate means higher EMI, (3) Loan Tenure — longer tenure means lower EMI but more total interest paid. Use our EMI calculator to see how changing each factor affects your monthly payment.

You can reduce your EMI by: (1) Increasing your loan tenure, (2) Making a larger down payment, (3) Negotiating a lower interest rate with your bank, (4) Prepaying part of the loan principal. Use our EMI calculator to compare different scenarios.

GST (Goods and Services Tax) is an indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes and has four main slabs: 5%, 12%, 18%, and 28%. Our GST calculator helps you instantly calculate GST on any amount.

CGST (Central GST) is collected by the Central Government, SGST (State GST) is collected by the State Government — both apply on intra-state transactions. IGST (Integrated GST) applies on inter-state transactions and is collected by the Central Government. Our GST calculator automatically splits the tax for you.

To calculate GST: GST Amount = (Original Price × GST Rate) / 100. Final Price = Original Price + GST Amount. For example, if a product costs ₹1000 with 18% GST: GST = ₹180, Final Price = ₹1180. Use our free GST calculator to do this instantly!

A Percentage Calculator is a free online tool that helps you calculate percentages instantly. You can find what percentage one number is of another, calculate percentage increase or decrease, or find a percentage of any number.

To calculate percentage of a number: Result = (Percentage × Number) / 100. For example, 20% of 500 = (20 × 500) / 100 = 100. Use our free Percentage Calculator to do this instantly without any manual calculation!

Percentage Change = ((New Value – Old Value) / Old Value) × 100. If the result is positive it’s an increase, if negative it’s a decrease. For example, price increased from ₹100 to ₹120: Change = ((120-100)/100) × 100 = 20% increase.

Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, compound interest grows exponentially over time — making it very powerful for long-term investments.

Simple Interest is calculated only on the principal amount. Compound Interest is calculated on principal plus accumulated interest. For example, ₹10,000 at 10% for 3 years: Simple Interest = ₹3,000. Compound Interest = ₹3,310. The difference grows bigger over longer periods.

The more frequently interest compounds, the more you earn. Monthly compounding gives more returns than annual compounding. Our Compound Interest Calculator lets you choose daily, monthly, quarterly or annual compounding so you can compare the difference easily.

A SIP (Systematic Investment Plan) Calculator helps you estimate the returns on your mutual fund investments. It calculates how much wealth you can accumulate by investing a fixed amount every month over a period of time at an expected rate of return.

The amount depends on your financial goals, income and risk appetite. A common rule is to invest at least 20% of your monthly income. Use our SIP calculator to work backwards — enter your target amount and see how much you need to invest monthly to reach it.

SIP in mutual funds historically gives higher returns (10-15% annually) compared to Fixed Deposits (5-7%). However, SIP carries market risk while FD is guaranteed. Use our Compound Interest Calculator to compare FD returns with our SIP Calculator to see the difference over time.

Our Age Calculator works by calculating the difference between your date of birth and today’s date (or any date you choose). It gives you your exact age in years, months and days, plus tells you how many days until your next birthday!

Discount Amount = (Original Price × Discount %) / 100. Final Price = Original Price – Discount Amount. For example, ₹2000 product with 25% discount: Discount = ₹500, Final Price = ₹1500. Use our free Discount Calculator to get instant results!
