- [Net Profit Margin - Glossary](https://calculations.tools/glossary/net-profit-margin): Net Profit Margin is Net Income as a percentage of revenue. It is the most comprehensive profitability ratio - the percentage of each revenue dollar that ultimately belongs to shareholders after all costs.
- [Operating Expenses (OpEx) - Glossary](https://calculations.tools/glossary/operating-expenses): Operating Expenses (OpEx) are the ongoing costs of running the business that are not directly tied to production. They include SG&A, R&D, and depreciation of operating assets - but not interest or tax.
- [Operating Profit - Glossary](https://calculations.tools/glossary/operating-profit): Operating Profit (also called EBIT) is the profit generated from core business operations after deducting COGS and all operating expenses, but before interest and tax. It isolates operational performance from financing and tax effects.
- [Operating Profit Margin - Glossary](https://calculations.tools/glossary/operating-profit-margin): Operating Profit Margin (also called EBIT Margin) is Operating Profit as a percentage of revenue. It shows how efficiently a business converts revenue into operating profit, excluding financing and tax effects.

- [Revenue - Glossary](https://calculations.tools/glossary/revenue): Revenue (also called "the top line" or "turnover") is the total income earned from selling goods or services before any costs are deducted. Every profitability metric - gross margin, EBITDA, net profit - is derived from revenue.
- [R&D (Research and Development) - Glossary](https://calculations.tools/glossary/rnd): R&D (Research and Development) expense is the cost of activities aimed at discovering new products, processes, or technologies. Under US GAAP, nearly all R&D costs are expensed immediately - reducing reported profit even though the spending may generate competitive advantages for years.
- [SG&A - Glossary](https://calculations.tools/glossary/sga): SG&A (Selling, General & Administrative expenses) are the overhead costs of running the business: sales force, marketing, executive salaries, rent, and back-office functions. SG&A is deducted from Gross Profit to arrive at Operating Profit.
- [Working Capital - Glossary](https://calculations.tools/glossary/working-capital): Working Capital is the difference between current assets (cash, receivables, inventory) and current liabilities (payables, short-term debt). It measures a company's short-term liquidity - its ability to meet obligations due within a year.
- [Break-Even Point - Glossary](https://calculations.tools/glossary/break-even-point): The break-even point is the level of sales at which total revenue exactly equals total costs - producing neither profit nor loss. It is the minimum volume a business must reach before generating operating profit.
- [CAGR (Compound Annual Growth Rate) - Glossary](https://calculations.tools/glossary/cagr): CAGR (Compound Annual Growth Rate) is the annualised rate at which an investment would have grown if it compounded at a steady pace each year. It smooths out year-to-year volatility to give a single comparable growth rate.
- [Compound Interest - Glossary](https://calculations.tools/glossary/compound-interest): Compound interest is interest calculated on both the original principal and all accumulated interest from prior periods. It causes wealth to grow exponentially over time - and debt to escalate at the same pace if left unpaid.
- [Contribution Margin - Glossary](https://calculations.tools/glossary/contribution-margin): Contribution Margin is revenue minus all variable costs - the amount each sale contributes toward covering fixed costs and then generating profit. It is the foundation of break-even analysis and per-product profitability decisions.
- [Current Ratio - Glossary](https://calculations.tools/glossary/current-ratio): The current ratio measures a company's ability to pay its short-term obligations using its short-term assets. A ratio above 1.0 means current assets exceed current liabilities; below 1.0 indicates potential liquidity risk.
- [Earnings Per Share (EPS) - Glossary](https://calculations.tools/glossary/eps): Earnings Per Share (EPS) is a company's net income divided by the number of shares outstanding. It converts total profit into a per-share figure that enables comparison across differently-sized companies and forms the denominator of the P/E ratio.
- [Pay Period - Glossary](https://calculations.tools/glossary/pay-period): A pay period is the recurring length of time for which an employer calculates and pays wages. Common types are weekly, bi-weekly (every two weeks), semi-monthly (twice a month), and monthly. Bi-weekly gives 26 pay cheques per year; semi-monthly gives 24.
- [Principal and Interest (P&I) - Glossary](https://calculations.tools/glossary/principal-and-interest): Principal and Interest (P&I) are the two components of a fixed-rate amortising loan payment. Principal reduces the outstanding balance; interest is the cost charged on that balance. Early payments are mostly interest; later payments are mostly principal - a shift called amortisation.
- [P/E Ratio (Price-to-Earnings) - Glossary](https://calculations.tools/glossary/pe-ratio): The P/E Ratio (Price-to-Earnings) is a stock's price divided by its annual earnings per share. It answers: how many dollars are investors paying for each dollar of profit? A higher P/E reflects higher growth expectations - or higher risk.
- [Return on Investment (ROI) - Glossary](https://calculations.tools/glossary/roi): Return on Investment (ROI) measures the net gain or loss on an investment relative to its cost, expressed as a percentage. It is the simplest and most universal metric for comparing the efficiency of different investments.

- [Return on Capital Employed (ROCE) - Glossary](https://calculations.tools/glossary/roce): ROCE measures how much operating profit (EBIT) a business generates per dollar of long-term capital deployed - both equity and long-term debt. Unlike ROE, it is unaffected by capital structure, making it the standard comparison metric for capital-intensive industries.
- [Return on Assets (ROA) - Glossary](https://calculations.tools/glossary/roa): Return on Assets (ROA) measures how much net income a company generates for each dollar of total assets - both debt-funded and equity-funded.

- [Free Cash Flow (FCF) - Glossary](https://calculations.tools/glossary/free-cash-flow): Free Cash Flow (FCF) is the cash generated by a business after funding its capital expenditure. It is the amount available to pay dividends, repay debt, buy back shares, or reinvest - the truest measure of a company's cash-generating ability.
- [Sales Tax - Glossary](https://calculations.tools/glossary/sales-tax): Sales tax is a government-imposed percentage added to the price of taxable goods and services at the point of sale. The seller collects it from the buyer and remits it to the state or local tax authority. In the US, 45 states levy a statewide sales tax; Alaska, Delaware, Montana, New Hampshire, and Oregon do not.
- [Value Added Tax (VAT) - Glossary](https://calculations.tools/glossary/value-added-tax): Value Added Tax (VAT) is a multi-stage consumption tax collected at each step of production and distribution.

- [Percentage Decrease - Glossary](https://calculations.tools/glossary/percentage-decrease): Percentage decrease measures how much a value has fallen relative to its original value. The result is always positive - the direction is implied. A value cannot decrease by more than 100% of itself.
- [Percentage Difference - Glossary](https://calculations.tools/glossary/percentage-difference): Percentage difference measures the relative gap between two values using their average as the base. Unlike percentage change, it is symmetric - the result is the same regardless of which value comes first.
- [Percentage Increase - Glossary](https://calculations.tools/glossary/percentage-increase): Percentage increase measures how much a value has grown relative to its original value. It is the standard way to express growth - revenue growth, price increases, population growth.
- [Percentage Point - Glossary](https://calculations.tools/glossary/percentage-point): A percentage point (pp) is the arithmetic difference between two percentage values. Rising from 3% to 5% is a 2 pp increase - and also a 66.7% relative increase. These describe the same event in very different ways.
- [Proportion - Glossary](https://calculations.tools/glossary/proportion): A proportion is a statement that two ratios are equal: a/b = c/d. It is solved using cross-multiplication and underlies scaling, unit conversion, recipe adjustment, and similar-triangle geometry.
- [Ratio - Glossary](https://calculations.tools/glossary/ratio): A ratio compares two or more quantities, showing their relative sizes. Written as a:b or a/b, it is the foundation for fractions, percentages, rates, and proportions - the core language of proportional reasoning.
- [Unit Rate - Glossary](https://calculations.tools/glossary/unit-rate): A unit rate is a ratio with a denominator of exactly 1, expressing how much of one quantity corresponds to a single unit of another. Speed in km/h, price per kg, and words per minute are all unit rates.

- [Body Composition - Glossary](https://calculations.tools/glossary/body-composition): Body composition is the proportional breakdown of the body into fat mass and lean mass (muscle, bone, water, organs). It is a more complete health indicator than body weight or BMI alone.
- [Body Fat Percentage - Glossary](https://calculations.tools/glossary/body-fat-percentage): Body fat percentage is the proportion of total body weight that consists of fat tissue. It is a more accurate health marker than BMI because it distinguishes fat mass from lean mass.
- [FFMI (Fat-Free Mass Index) - Glossary](https://calculations.tools/glossary/ffmi): FFMI (Fat-Free Mass Index) is lean body mass divided by height squared - the muscle-equivalent of BMI. It measures muscularity relative to frame size, independent of body fat percentage.
- [Ideal Body Weight (IBW) - Glossary](https://calculations.tools/glossary/ideal-body-weight): Ideal Body Weight (IBW) is a clinical estimate of target weight based on height and sex, derived from the Devine, Robinson, Miller, and Hamwi formulas. It was originally developed for drug dosing, not fitness targets.
- [Lean Body Mass (LBM) - Glossary](https://calculations.tools/glossary/lean-body-mass): Lean Body Mass (LBM) is total body weight minus fat mass - everything that is not fat: muscle, bone, organs, blood, skin, and water. LBM drives basal metabolic rate and is the basis for drug dosing calculations.
- [Bioelectrical Impedance Analysis (BIA) - Glossary](https://calculations.tools/glossary/bioelectrical-impedance-analysis): Bioelectrical Impedance Analysis (BIA) estimates body fat and lean mass by passing a small electrical current through the body. Fat tissue resists the current more than muscle and water; the measured resistance is fed into prediction equations to derive body fat percentage.
- [GST (Goods and Services Tax) - Glossary](https://calculations.tools/glossary/gst): GST (Goods and Services Tax) is the name used in Australia, Canada, India, New Zealand, and Singapore for a tax that works identically to VAT - collected at each stage of production with businesses reclaiming input tax. The math and mechanics are the same; only the name differs.
- [Gross Pay - Glossary](https://calculations.tools/glossary/gross-pay): Gross pay is the total amount earned before any deductions - income tax, Social Security, Medicare, health insurance premiums, or retirement contributions. It is the figure quoted in salary offers and used to calculate hourly rates.
- [Net Pay - Glossary](https://calculations.tools/glossary/net-pay): Net pay is take-home pay - the amount deposited into your bank account after all mandatory and voluntary deductions are removed from gross pay. For most US workers, net pay is 65-75% of gross pay depending on tax bracket and benefit elections.
- [RPM (Revenue Per Mille) - Glossary](https://calculations.tools/glossary/rpm): RPM (Revenue Per Mille) is the estimated earnings per 1,000 page views on an ad-supported website.

It is calculated as (total clicks / total impressions) x 100. A CTR of 1-3% is typical for content sites using Google AdSense banner ads.
- [Waist Circumference - Glossary](https://calculations.tools/glossary/waist-circumference): Waist circumference measures abdominal girth at the natural waist. It is a direct indicator of visceral fat - the most metabolically harmful fat depot - and predicts cardiometabolic risk independently of BMI.
- [Merit Increase - Glossary](https://calculations.tools/glossary/merit-increase): A merit increase is a salary raise awarded based on individual job performance, distinct from cost-of-living adjustments. U.S. employers typically budget separate merit pools of 3-5%, distributed according to performance ratings, with high performers receiving a larger share.
- [Cost-of-Living Adjustment (COLA) - Glossary](https://calculations.tools/glossary/cost-of-living-adjustment): A cost-of-living adjustment (COLA) is an automatic salary or benefit increase tied to a price index - usually the Consumer Price Index (CPI) - to preserve purchasing power as prices rise. Social Security applies an annual COLA; many employers issue a COLA separately from merit increases.
- [Overtime Pay - Glossary](https://calculations.tools/glossary/overtime-pay): Overtime pay is the additional compensation earned for hours worked beyond a set threshold - typically 40 hours per week in the US. Under the FLSA, non-exempt employees must receive at least 1.5 times their regular rate for overtime hours.
