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.
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.

Who Uses These Calculators
Retail investors and salaried professionals use the fixed-income and SIP calculators for routine savings and mutual fund planning. Financial analysts and corporate finance professionals use the NPV, IRR, MIRR, and DCF calculators for capital budgeting and project appraisal - MIRR in particular is used whenever a project has irregular cash flows that make plain IRR unreliable or non-unique. Equity research analysts and value investors use the dividend discount model and DCF calculators to estimate intrinsic stock value against market price. CFOs and business owners use ROIC to check whether a business is creating or destroying economic value relative to its cost of capital. Active traders use the moving average, stock average, and forward premium calculators for technical analysis, cost-basis tracking, and FX hedging decisions.

Frequently Asked Questions
What return rate should I assume for the SIP calculator?
For equity mutual funds, 10–12% annualised return is a commonly used long-term assumption based on historical Nifty 50 CAGR. Debt funds typically use 6–8%. The SIP Calculator lets you try multiple scenarios.
Does the PPF calculator account for the 15-year lock-in?
Yes. The PPF Calculator enforces the 15-year minimum tenure, models the government-set interest rate (revised quarterly — verify the current rate at indiapost.gov.in or your bank), and supports the 5-year extension blocks available after maturity.
What is the difference between CAGR and absolute ROI?
Absolute ROI ignores time - a 50% return over 10 years and over 2 years look the same. CAGR normalises for time, giving the equivalent annual growth rate. Always use CAGR when comparing investments with different durations.
How does compounding frequency affect FD returns?
More frequent compounding increases effective yield. A 7% FD compounded quarterly yields an effective annual rate of 7.19%. Indian bank FDs are compounded quarterly per RBI guidelines - the FD Calculator handles this automatically.
What is the difference between IRR and MIRR?
IRR (Internal Rate of Return) finds the discount rate that makes a project's NPV exactly zero, but it implicitly assumes interim positive cash flows are reinvested at the IRR itself - an unrealistic assumption for high-IRR projects, and one that can also produce multiple or no valid IRR solutions when cash flows change sign more than once. MIRR (Modified IRR) fixes both problems by using a separate, realistic finance rate for negative cash flows and reinvestment rate for positive cash flows, always producing one unique, more conservative result. Use the IRR Calculator for a quick standard read and the MIRR Calculator when cash flows are irregular or the reinvestment assumption matters.
How is a stock's intrinsic value estimated with DCF and the dividend discount model?
Both methods discount a stream of future cash to today's value, but they use different cash flows: the DCF Calculator discounts a company's projected free cash flow (what the whole business generates), making it applicable to any company regardless of dividend policy. The Dividend Discount Model Calculator discounts expected future dividends specifically, using the Gordon Growth formula P0 = D1/(r−g) for a constant-growth dividend payer - it only works well for mature, stable dividend-paying companies, since it says nothing about the value of a non-dividend-paying growth stock.
