Investment Calculators

Investment Calculators - Project Your Wealth with Precision

Every investment decision benefits from clear numbers: How much will my SIP corpus be in 20 years? What is the effective yield on my FD? How does PPF compare to ELSS over 15 years? These calculators give exact projections so you can compare options, set realistic targets, and understand the compounding effect on your wealth.

Twenty-Four Investment Calculators

Investment Calculator - Projects future value of a lump sum or monthly contributions at any return rate. Choose compounding frequency, see year-by-year growth, and compare invested capital to total gains with an interactive pie chart.

Future Value Calculator - Full time-value-of-money (TVM) solver with four modes: Find Future Value (FV = PV x (1+r/n)^nt), Find Present Value, Find Rate (implied CAGR), and Find Time. Shows effective annual rate (EAR) and growth factor for every calculation.

Present Value Calculator - Three-mode PV calculator: Lump Sum (PV = FV/(1+r/n)^nt), Annuity (ordinary and annuity due), and Perpetuity (fixed and Gordon Growth Model growing perpetuity). Used for bond pricing, pension valuation, and equity DDM.

SIP Calculator - Projects the future value of a Systematic Investment Plan using the annuity formula FV = P × ((1+r)^n − 1) / r × (1+r). Shows invested amount, estimated returns, and total corpus.

Compound Interest Calculator - A = P(1 + r/n)^(nt) with selectable compounding frequency (annual, semi-annual, quarterly, monthly, daily). Demonstrates why monthly compounding beats annual compounding for the same stated rate.

FD Calculator - Fixed deposits with guaranteed returns. Supports both cumulative (reinvested) and non-cumulative (payout) FDs with quarterly compounding per RBI mandate.

RD Calculator - Recurring Deposit maturity value, total deposited, and total interest earned for monthly fixed-return savings schemes.

PPF Calculator - Public Provident Fund with EEE tax treatment and government-set rate (7.1% p.a. as of FY25). Models the annuity-due interest crediting structure over the 15-year lock-in, with optional 5-year extension blocks.

Simple Interest Calculator - SI = P × R × T / 100. Useful for short-term instruments and as a baseline comparison against compound growth.

CAGR Calculator - Compound Annual Growth Rate: (End Value / Begin Value)^(1/Years) - 1. The standard metric for comparing investment performance across different time periods.

CAGR Calculator: Compound Annual Growth Rate - Three-mode CAGR solver: Find CAGR (enter start value, end value, years), Find Ending Value (project future value at a given CAGR), Find Years Needed (how long to reach a goal). Shows total return, net gain, investment multiple, and Rule of 72 doubling time. Multi-currency support.

ROI Calculator - Return on Investment = (Gain - Cost) / Cost x 100. Evaluates any investment where you know total gain and total cost, regardless of time period.

ROI Calculator: Return on Investment - Two-mode ROI calculator: Investment Return (initial cost, final value, years held, outputs ROI%, annualized CAGR, net gain/loss, investment multiple) and Business/Marketing ROI (revenue vs. cost, outputs ROI%, profit, cost per revenue dollar, and break-even revenue). Multi-currency support.

Moving Average Calculator - Compute Simple Moving Average (SMA) and Exponential Moving Average (EMA) for any data series. Enter values as a comma or newline-separated list, set the window period, and see the latest MA, trend direction (rising/falling/flat), and all computed values. Works for stock prices, sales data, or any time series.

Stock Average Calculator - Calculate your weighted average cost per share across multiple purchases at different prices. Add unlimited buy lots, see total cost basis, total shares, and price range. Models averaging-down, dollar cost averaging, and any multi-tranche equity position.

IRR Calculator - Internal Rate of Return: find the discount rate that makes NPV = 0 for any project with up to 15 cash flows. Uses Newton-Raphson iteration. Compare IRR to your hurdle rate for instant Accept/Reject decisions. Also shows NPV at the hurdle rate as a cross-check. Essential for capital budgeting, project appraisal, and investment evaluation.

MIRR Calculator - Modified Internal Rate of Return: addresses IRR’s reinvestment assumption flaw by using separate finance rate (for negative cash flows) and reinvestment rate (for positive cash flows). Always produces a unique result even when cash flows change sign multiple times. Up to 10 years of cash flows, Accept or Reject vs hurdle rate, and side-by-side IRR comparison.

NPV Calculator - Net Present Value: discount future cash flows at your required rate of return and compare to the initial investment. Enter any number of annual cash flows, see NPV (green = positive = accept), present value of inflows, profitability index, and an Accept/Reject recommendation.

NPV Calculator — Net Present Value - Two-mode NPV calculator: Variable Cash Flows (enter individual annual cash flows and optional terminal value for any project) and Uniform Annuity (fixed cash flow every year using the PV of annuity formula). Shows NPV with Accept/Reject signal, PV of cash flows, total undiscounted cash flows, and Profitability Index. Multi-currency support.

Continuous Compound Interest Calculator - Four modes to solve A = Pe^(rt): find future value, principal, annual rate, or time. Also shows Effective Annual Rate (EAR = e^r − 1). Used in advanced finance, derivatives pricing, and comparing compounding frequencies.

Percentage Return Calculator - Two modes: (1) simple total return - (Final − Initial + Income) / Initial × 100; (2) annualized return (CAGR) over multiple years. Supports dividends in both modes. Used for evaluating mutual funds, stocks, real estate, and any investment with a start and end value.

Compound Interest Rate Calculator - Two modes: (1) Find Rate - solve r = n x ((A/P)^(1/nt) - 1) to find the annual interest rate from principal, final amount, and time; (2) Find Time - solve t = ln(A/P) / (n x ln(1 + r/n)) to find how long to reach a target amount. Also shows Effective Annual Rate (EAR) and growth factor.

Discount Rate Calculator - Two modes: (1) Find Discount Rate - given present value, future value, and years, compute r = (FV/PV)^(1/n) - 1 (equivalent to CAGR); (2) Find Present Value - given future value, discount rate, and years, compute PV = FV / (1+r)^n. Shows total return %, growth multiple, total gain, discount amount, and discount percentage. Used for DCF analysis, investment appraisal, and time-value-of-money calculations.

DCF Calculator — Discounted Cash Flow - Estimate the intrinsic value of a stock or business using two approaches: Cash Flows mode (enter projected annual cash flows and a terminal value directly) and Two-Stage Growth mode (Gordon Growth Model — enter current FCF, high-growth rate, projection years, terminal growth rate, and WACC). Shows PV of projected cash flows, PV of terminal value, total intrinsic value, and margin of safety versus current market price.
