A sample of what is live

• Stock Total Return & CAGR Calculator — Calculate total return on a stock or index fund holding, factoring in capital appreciation, cash or reinvested dividends (DRIP), and compound annual growth rate (CAGR).
• Price-to-Book Calculator — The full price tag for price-to-book: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Intrinsic Value (DCF) Calculator — A transparent linear conversion for intrinsic value (dcf): the factor is visible, the arithmetic is shown, and the inverse direction comes free.
• Tobin's Q Calculator — The share one quantity represents of another — the core reading behind tobin's q — with a second value folded in for direct comparison.
• Short Squeeze Potential Calculator — The share one quantity represents of another — the core reading behind short squeeze potential — with a second value folded in for direct comparison.
• Cyclically Adjusted P/E Calculator — A transparent linear conversion for cyclically adjusted p/e: the factor is visible, the arithmetic is shown, and the inverse direction comes free.
• Portfolio Return Calculator — The one-period weighted blend of asset returns — arithmetic is all it takes. The real lesson is attribution: which slice of the pie actually produced (or destroyed) the number.
• Omega Ratio Calculator — The size and shape of the move between two figures — total percent, absolute delta and the annualised rate — for omega ratio.
• Beta Calculator — Fisher Black called it "the most misused statistic in finance," and he was right to be careful: beta is the slope of an asset's historical response to the market — sensitivity, not risk by itself, and not causal.
• Drift Calculator Calculator — The share one quantity represents of another — the core reading behind drift calculator — with a second value folded in for direct comparison.
• Market Cap Weight Calculator — The share one quantity represents of another — the core reading behind market cap weight — with a second value folded in for direct comparison.
• ESG Score Impact Calculator — Attainment of esg score impact against a target, with the absolute gap and the weighted contribution for scorecard roll-ups.
• Black-Scholes Option Pricing & Greeks Calculator — Calculate fair theoretical European Call and Put option prices using the Black-Scholes-Merton formula, with all 5 Greeks (Delta, Gamma, Theta, Vega, Rho) and an interactive expiration payoff diagram.
• Theta Calculator — The daily rent on an option — how much value evaporates if the market does nothing. It is the counterparty of gamma: the price paid for holding convexity, and the income of every premium-selling strategy.
• Zomma Calculator — Bridges vol and convexity: how much gamma you gain or lose as the vol regime shifts. In a crisis it decides whether your hedges get sharper exactly when you need them to — or duller.
• Options Breakeven Calculator — The price the market must reach for the trade to be flat at expiry — the honesty check every long-premium idea must pass, because options do not merely need direction, they need direction faster than the clock.
• Bear Put Spread Calculator — A transparent linear conversion for bear put spread: the factor is visible, the arithmetic is shown, and the inverse direction comes free.
• Back Spread Calculator — The share one quantity represents of another — the core reading behind back spread — with a second value folded in for direct comparison.
• Bond Valuation, Clean/Dirty Price & Convexity Curve Calculator — Calculate bond fair present value, clean and dirty price with accrued interest, Macaulay duration, and plot the non-linear price-yield convexity curve.
• Dirty Price Calculator — The real money that changes hands. Quotations are clean for comparability across coupons, but settlement is dirty — accrued interest goes to the seller.
• Option-Adjusted Spread Calculator — The bottom line for option-adjusted spread and the margin it represents — the two numbers every owner checks before anything else.
• Expected Loss Calculator — The Basel and IFRS 9 workhorse: what a credit portfolio statistically loses per year, as the product of who might fail (PD), how much the failure costs (LGD) and how much is at stake (EAD). Pricing must clear EL; capital exists for everything above it.
• Taxable Equivalent Yield Calculator — Income relative to price — the taxable equivalent yield number investors quote first — plus the expense-adjusted net figure that actually matters.
• Barbell Strategy Calculator — The bottom line for barbell strategy and the margin it represents — the two numbers every owner checks before anything else.

How the Investing & Markets engines are built

Three things hold every tool in this category together. The calculation is a real formula rather than a lookup of someone else's rounded answer, so unusual inputs behave sensibly. The result comes with interpretation — verdict bands, the gap against a target, or the range a reasonable change in assumptions moves it. And the guide on each page is generated from that engine's own numbers, which is why two adjacent tools in the same sub-topic do not hand you the same paragraph with a different noun pasted in.

Where this sits in the library

Investing & Markets is one of 21 categories among the 3,602 engines The Online Calculator 24 serves today. The full index is at all categories, and the General workbench covers ROI, payback, margin, break-even and cost-per-unit for figures that do not fit a dedicated tool.
