05Break-even point
Minimum sales to cover fixed costs. Indivisible units round up; do not count allocated fixed costs twice.
Open calculatorSelling price and margin
Margin uses sales after commissions; markup uses cost. Price rounds up to preserve the target margin.
Open calculatorTrue product cost
Batch cost divided by sellable units, plus packaging and delivery. Overhead allocations are shown separately.
Open calculatorDiscounts and promotions
Compare normal and promotional contribution at constant cost. A discount does not automatically imply greater demand.
Open calculatorProfitability by product or customer
Revenue less direct costs and service time. Allocated overhead is not necessarily avoidable.
Open calculatorCash and financing
05Cash flow forecast
Expected cash receipts and payments, not accounting revenue. A positive month-end balance does not prove daily liquidity. One-off payments occur at the start.
Open calculatorBusiness cash runway
Free cash divided by constant monthly net burn. Fractional months assume uniform burn.
Open calculatorStartup capital required
Initial payments, maximum cumulative startup deficit and reserve. Available funds reduce the outstanding amount, not total need.
Open calculatorLoan cost
Monthly installments at month-end; annual nominal rate divided by twelve. Final installment adjusts rounding. Effective rate is a financial estimate without regulatory validation.
Open calculatorCash needed to grow
Thirty-day months and purchases equal to merchandise cost. Negative working capital is not automatically available cash.
Open calculatorSales and marketing
05Campaign profitability
Attributed result after variable cost and advertising. ROAS measures revenue, not profit; attribution does not prove incremental sales.
Open calculatorCustomer acquisition cost
Costs aligned with a cohort of new customers; exclude repeat purchases. Paid-channel CAC requires identified customers from that channel.
Open calculatorCustomer value
Expected twelve-month contribution, with extra support and year-end discounting. Not observed value or necessarily lifetime value.
Open calculatorConversion funnel
Each stage rate multiplies the previous volume. Fractional results are forecasts, not observed counts.
Open calculatorBudget to reach a target
Required orders and visits round up. Organic visits are deducted first. Conversion and traffic cost stay constant.
Open calculatorSubscriptions and startups
05Subscription growth
Churn affects starting customers; additions occur at close and bill from next month. Normalized MRR is not cash receipts; annual prices divide by twelve.
Open calculatorChurn impact
Cohort without new additions. Monthly revenue uses opening customers; churn occurs at close. Final MRR loss and cumulative loss are separate.
Open calculatorAcquisition cost payback
Monthly contribution with churn at close; free months yield no contribution. Retention-adjusted payback is shown only if reached within the horizon.
Open calculatorFunding rounds and dilution
Primary ordinary-share round; excludes convertibles, preferences and secondary sales. Pre-round pool uses previous equity; post-round pool uses final total.
Open calculatorFunding to the next milestone
Monthly burn, one-off initial payments and reserve against existing cash. Calculates maximum cash deficit, not only final balance.
Open calculatorTeam and operations
05Hiring cost
Manual mode: annual gross salary, employer charges and recurring costs. Onboarding only in year one; employee withholding is not extra employer cost.
Open calculatorHourly or project rate
Costs include personal remuneration; billable hours, not all worked hours. Contingency applies to project hours; external costs before margin.
Open calculatorHire, outsource or automate
Same volume and horizon for three options. Automation investment counted once. Capacity checked separately; lower cost does not guarantee equal quality.
Open calculatorAutomation return
Released hours valued economically; cash savings only for avoidable cost share, less maintenance. Released time does not imply avoided payments.
Open calculatorInventory and replenishment
Constant demand and lead times. Position includes usable stock plus incoming orders minus backorders. Orders only at reorder point; applies minimums and multiples.
Open calculatorInvestment and planning
05Business investment return
Investment at time zero, flows at year-end and residual in final year. Payback indicates collection year; no payment interpolation. IRR only for conventional flows with a unique root.
Open calculatorBuy, rent or finance
Same asset and use. Financing: down payment plus installments, without adding purchase price again. Resale at end; annual effective discount converted monthly. Rental without extra maintenance.
Open calculatorProfit targets
Sales to cover fixed costs and operating profit before tax. Margin after variable costs and before those fixed costs; not after-tax net profit.
Open calculatorInflation, energy and currencies
Manual changes at constant volume. Additional foreign purchase separate from other costs; exchange rate in selected currency per foreign unit.
Open calculatorBusiness scenarios
Approximate cash assumes immediate receipts and payments, no tax, debt or delays. Use flow schedule for real cash differences. Scenarios are not probabilities.
Open calculatorNo calculators match those filters.
