About Investment
Financial calculators are essential tools for making informed investment, borrowing, and tax decisions. Whether you're planning a Systematic Investment Plan (SIP) in mutual funds, calculating a home loan EMI, estimating your income tax liability, or planning for retirement, having accurate projections helps you make better financial choices.
A SIP (Systematic Investment Plan) lets you invest a fixed amount in mutual funds at regular intervals. The power of compounding means even small monthly investments can grow into significant wealth over time. EMI (Equated Monthly Installment) calculators help you understand your loan repayment schedule before committing to a home or car loan.
ForgeKit's Investment & Financial Calculators suite includes 35+ calculators covering investments (SIP, lumpsum, SWP, step-up SIP, CAGR, XIRR), savings (FD, RD, PPF, EPF, SSY, NSC, SCSS), loans (EMI, home loan, car loan, flat vs reducing rate), taxes (income tax, HRA, TDS, GST, gratuity), and planning (NPS, retirement, inflation). Each calculator features interactive sliders, donut charts, and year-by-year breakdowns. All calculations run in your browser — your financial data stays private.
Frequently Asked Questions
A SIP (Systematic Investment Plan) calculator estimates the future value of regular monthly investments in mutual funds, assuming a given annual return rate and investment period. It shows the power of compounding over time.
The EMI formula used is the standard reducing balance method: EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P is principal, r is monthly interest rate, and n is number of months. This is the same formula used by banks.
No. All calculations run entirely in your browser using JavaScript. No data is sent to any server, stored in any database, or shared with any third party.
Yes. The income tax calculator supports both the old regime (with exemptions and deductions) and the new regime (lower rates, fewer deductions) so you can compare which is more beneficial for you.
XIRR (Extended Internal Rate of Return) calculates the annualized return on investments with irregular cash flows. Unlike CAGR which assumes a single lump sum, XIRR handles multiple investments made on different dates.
