Stock market tools & calculators
Free, private tools that run entirely in your browser — nothing you type is sent anywhere. They do the arithmetic from your inputs and the published exchange schedule. They are educational utilities, not investment advice.

Open →NiftyLens provides general educational information and user-input mathematical utilities. It does not provide personalised investment advice, research recommendations, trade calls, price targets or suitability assessments. Market-calendar, settlement and transaction-cost information may change and should be verified against current official exchange, clearing, broker, depository and tax records. Trading and investing involve risk; you remain responsible for your own decisions and should seek appropriately qualified professional advice where needed.
