Business & Entrepreneurship calculators

304 live business & entrepreneurship tools on The Online Calculator 24, grouped into 6 sub-topics — startup metrics, sales & revenue, marketing & growth, operations, hr & compensation, financial analysis. Each one publishes the formula it uses, works the arithmetic step by step from its own starting figures, and names the standard, regulation or dataset the math traces back to, so you can check an answer instead of trusting it.

A sample of what is live

• Startup Valuation, Funding Round & Dilution Calculator — Calculate Post-Money Valuation, new investor equity percentage, founder dilution, and price per share across priced financing rounds.
• Priced Round Impact Calculator — One round's full ownership shift: the new-money shares plus any pool expansion priced at the same valuation, so founders see the total movement, not the headline percentage.
• VC IRR Calculator — The time-corrected multiple: the compound annual rate that turns the invested dollar into the exit dollar.
• Carried Interest Calculator — The GP's share of profits: 20% of gains above an 8% preferred return — whether the hurdle compounds and how the waterfall tests it decide how much carry truly arrives.
• AUM Calculator — Working the fee schedule backwards: from revenue and tiered basis points, recover the assets that must be producing it — and the blended rate that really describes the book.
• Cohort LTV Calculator — The per-customer gross-profit sum, capped at a modeling horizon because no exponential churn curve deserves infinity.
• Sales Pipeline Revenue Forecast & Probability Weighting Calculator — Calculate expected revenue using the industry-standard probability-weighted sales pipeline methodology across Discovery, Qualification, Proposal, and Negotiation stages.
• Win Rate Calculator — The share of decided opportunities that close — the single most leverage-heavy number in a sales model because it multiplies pipeline, headcount and forecast alike.
• Opportunity to Close Calculator — The closing stage proper: of everything qualified into the pipeline, how much actually signs. It is the number win-rate hawks watch and the one forecast committees argue over.
• Upsell Rate Calculator — Share of eligible customers moving to a richer tier — the purest test of whether the product keeps earning value as customers grow.
• Revenue per Sales Rep Calculator — The productivity line of the GTM engine — booked new business divided by the quota-carrying headcount that produced it.
• Discount Impact Calculator — See how a discount really affects profit margin — and how many extra units you must sell to break even on the price cut.
• Customer Acquisition Cost (CAC) & Blended Efficiency Calculator — Calculate your fully-loaded Customer Acquisition Cost (CAC), separating Paid CAC from Blended CAC by accounting for ad spend, sales commissions, marketing salaries, and software overhead.
• LTV:CAC Benchmark Calculator — Builds the ratio from primitives — unit price, margin, churn, CAC — so the benchmark test can be run on the real inputs instead of a quoted LTV.
• CPAC Calculator — Cost per acquired customer — order metrics deduped down to first-time buyers, the acquisition truth that order-based numbers hide.
• Click-Through Rate Calculator — Share of impressions that become clicks — the creative-quality gate of every paid and owned channel, and the CTR that ad platforms price on.
• Split Test Sample Size Calculator — The pre-flight calculation for an A/B test: visitors per arm needed to detect a stated relative lift at chosen confidence and power.
• Backlink Value Calculator — Prices a link by the visitors it actually sends over its expected life — before any algorithmic ranking benefit, which is the volatile half.
• Overall Equipment Effectiveness (OEE) & Six Big Losses Calculator — Calculate Overall Equipment Effectiveness (OEE) for manufacturing and operations, multiplying Availability, Performance, and Quality against the World-Class 85% TPM standard.
• Fulfillment Time Calculator — The clock from order acceptance to delivered — split into your warehouse’s processing hours and the carrier’s transit hours, because each is fixed differently.
• Six Sigma DPMO Calculator — Defects normalised per million opportunities and converted to the sigma scale — the shared language that compares a form process to a PCB line.
• Lean Savings Calculator — Stacks the three savings currencies of lean work — released hours, released space and reduced material loss — into one annual figure.
• Economic Order Quantity Calculator — The order size that trades ordering cost against carrying cost at their intersection — inventory theory’s founding formula.
• Disruption Cost Calculator — The event ledger: lost contribution plus the fixed-cost burn that continues regardless, plus recovery spend, per day and in total.
• Salary Benchmarking Calculator — Where one salary sits against the market for the same role — expressed as a ratio to median and an approximate percentile band.
• Incentive Pay Calculator — What a variable-pay plan actually delivers at a given attainment, including the common shape: straight pro-rata below target, accelerated above, capped at the top.
• Total Rewards Value Calculator — The complete employer-cost picture of one job: cash, benefits, equity, development and quality-of-life value, summed into a single number for the conversation.
• Paid Leave Cost Calculator — What paid absence genuinely costs: wage continuation, the premium of covering the seat, and payroll taxes on it all.
• Certification Value Calculator — Whether a professional credential pays: the wage premium it commands, discounted, against exam, training and time costs.
• Engagement ROI Calculator — Converting survey-point movement into dollars: payroll multiplied by points gained and the productivity elasticity engagement research reports.
• Revenue Growth Rate Calculator — How fast the top line is moving between two periods, annualized when the span covers more than a year — the single number growth investors check first.
• Levered FCF Calculator — Cash available to shareholders after reinvestment and after debt flows — the equity-owner version of free cash, the right discount quantity for cost of equity.
• Days Inventory Outstanding Calculator — How many days of cost flow sit frozen on the shelf — inventory speed expressed in days instead of turns.
• Enterprise Value Calculator — The price of the whole business — equity plus the debt you inherit minus the cash you receive. The correct denominator for every EV multiple.
• DCF Valuation Calculator — The present value of every future free cash flow a business will generate, split into an explicit forecast window and a terminal tail — valuation from first principles.
• IRR Calculator — The discount rate at which a project’s cash flows net to zero — the investment’s intrinsic compound rate, the number capital committees quote.

How the Business & Entrepreneurship 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

Business & Entrepreneurship 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.
