EMI, compound interest, SIP, loan amortization — smart money math, zero cost.
CalcHub's financial calculator suite covers the four most important personal finance calculations: EMI (Equated Monthly Installment) for loans, compound interest for savings and investments, SIP (Systematic Investment Plan) for mutual fund planning, and savings goal tracking. Whether you're planning a home loan, estimating retirement corpus, or deciding how much to invest monthly, these tools give you instant, accurate answers.
All calculations follow industry-standard formulas used by banks, financial advisors, and investment platforms. Results include full breakdowns showing principal vs interest components, helping you understand exactly where your money goes or grows.
The EMI formula calculates a fixed monthly payment that covers both principal and interest over the loan tenure. For a loan of principal P at monthly interest rate r over n months, EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1). The amortization schedule generated by our tool shows month-by-month breakdown of how much of each payment goes toward interest versus principal. In early months, the interest component dominates; over time, the principal share grows — this is the nature of reducing-balance loans.
Compound interest is widely called the "eighth wonder of the world" because returns generate their own returns. Our calculator uses A = P(1 + r/n)^(nt), where P is principal, r is annual interest rate, n is compounding frequency per year, and t is time in years. The difference between quarterly and annual compounding over long periods can amount to hundreds of thousands of rupees — which is why understanding compounding frequency matters.
A Systematic Investment Plan involves investing a fixed amount every month into a mutual fund. The future value of SIP uses FV = PMT × ((1 + r)ⁿ − 1) / r × (1 + r), where PMT is the monthly payment, r is the monthly rate, and n is total months. SIPs leverage rupee cost averaging — you buy more units when markets are low and fewer when high, reducing the impact of volatility over long periods.
