How to choose business calculators
Match the calculator to the decision and the figures you have. Business Profit Calculator groups several profit measures, Marketing Metrics Calculator compares campaign ratios, SaaS Metrics Calculator combines recurring-revenue measures, and Inventory Planning Calculator puts stock formulas in one scenario.
Profit calculators for margin, pricing, and break-even
Use Business Profit Calculator when one scenario needs COGS, gross and net profit margin, markup, break-even units and revenue, projected profit, or billable hourly rate. Choose a focused calculator when one result needs a narrower set of inputs.
- Gross Margin Calculator uses revenue and direct cost to calculate gross profit and gross margin.
- Net Profit Margin Calculator uses revenue, operating expenses, interest, and tax.
- Markup Calculator finds markup or margin from cost and selling price, or calculates a target selling price or cost.
- Break-Even Revenue Calculator uses fixed costs, price per unit, and variable cost per unit.
- Project Profit Calculator uses project revenue, labor, materials, overhead, and an optional estimated tax rate.
- Billable Hourly Rate Calculator uses an income target, business expenses, working hours, and utilization rate.
Gross Margin Calculator uses direct cost. Net Profit Margin Calculator also uses operating expenses, interest, and tax. Markup Calculator uses cost and selling price, or a target markup or margin, so it answers a different pricing question.
Marketing metrics calculators for campaign ratios
Marketing Metrics Calculator compares ROAS, CPM, CPC, CTR, and conversion rate across campaign rows. Enter the figures yourself, and the calculator shows each metric's numerator and denominator. It has no live ad data and does not assign attribution automatically.
- ROAS Calculator compares attributed revenue with advertising spend.
- CPM Calculator uses advertising spend and impressions.
- CPC Calculator uses advertising spend and clicks.
- CTR Calculator uses clicks and impressions.
- Conversion Rate Calculator uses conversions and a matching visitor, lead, session, click, or custom total.
- Customer Acquisition Cost (CAC) Calculator uses sales and marketing spend plus new customers.
Use Marketing Metrics Calculator when several campaign rows belong in one review. Open CPC Calculator, CTR Calculator, or another focused page when one ratio needs separate inputs. Keep the campaign scope and attribution basis consistent across rows.
SaaS calculators for revenue, retention, and growth
SaaS Metrics Calculator combines MRR, ARR, CAC, LTV, customer and revenue churn, expansion and contraction, gross and net burn, cash runway, and Rule of 40 in one period of SaaS data.
- ARR Calculator uses recurring revenue and the billing period to calculate ARR.
- MRR Calculator reports starting MRR plus new, expansion, contraction, and churned MRR.
- Churn Rate Calculator calculates customer or revenue churn rate from starting, lost, gained, and ending customers or revenue.
- Customer Lifetime Value (LTV) Calculator uses average revenue per customer, gross margin, and churn or retention rate.
- SaaS Rule of 40 Calculator uses a revenue growth rate and a supplied profit margin.
Keep monthly figures with monthly figures and annual figures with annual figures. LTV depends on the churn or retention rate and gross margin you enter. Rule of 40 depends on the growth rate and profit margin you enter.
Cash runway and inventory planning
Burn Rate Calculator uses cash balance, revenue, and expenses to calculate gross burn, net burn, and cash runway. Cash Runway Calculator uses cash balance, revenue, and burn assumptions for a runway estimate and month-by-month projection. Both use entered figures, not live financial records.
Inventory Planning Calculator puts reorder point, safety stock, EOQ, and inventory turnover in one scenario. Its inputs cover demand, demand variability, lead time, service level, ordering cost, holding cost, COGS, and average inventory.
- Cost of Goods Sold Calculator uses starting inventory, purchases, and ending inventory.
- Economic Order Quantity (EOQ) Calculator uses demand, ordering cost, and holding cost.
- Reorder Point Calculator uses average daily demand, maximum daily demand, and lead time.
- Safety Stock Calculator uses demand variability, lead-time variability, and a target service level with a statistical Z-score method.
- Inventory Turnover Calculator uses COGS and average inventory to report turnover and days of inventory on hand.
Use Economic Order Quantity (EOQ) Calculator for order quantity, Reorder Point Calculator for the replenishment trigger, and Safety Stock Calculator when demand or lead-time variability and a target service level set the buffer. Keep units and time periods aligned in each inventory calculation.
Typical business calculator jobs
For a recurring-revenue review, enter starting MRR, new MRR, expansion, contraction, and churned MRR in MRR Calculator. Then use ARR Calculator with the relevant billing period.
For campaign review, enter spend, impressions, clicks, conversions, and revenue for each campaign in Marketing Metrics Calculator. Open a focused calculator when CPC or conversion rate needs a separate denominator.
For stock planning, compare demand and lead-time assumptions in Inventory Planning Calculator. Switch to Safety Stock Calculator when the service-level assumption needs its own result.
Choose by the question you need answered
Write down the output before entering values. Use an all-in-one calculator when the same inputs support several related measures. Use a focused page when one formula or one output is the point. For work outside business planning, choose the relevant section in Calculators.
Frequently asked questions
Which business calculator should I start with?
Match the inputs to the decision. Choose Business Profit Calculator, Marketing Metrics Calculator, SaaS Metrics Calculator, or Inventory Planning Calculator when one scenario needs several related measures.
What is the difference between gross margin and net profit margin?
Gross margin uses revenue and direct cost. Net profit margin also includes operating expenses, interest, and tax. Use Gross Margin Calculator for the direct-cost view and Net Profit Margin Calculator for the broader profit result.
Which calculator compares marketing metrics?
Marketing Metrics Calculator compares ROAS, CPM, CPC, CTR, and conversion rate across campaign rows. It uses entered figures, has no live advertising data, and does not assign attribution automatically.
Do these business calculators use live business data?
They use the figures and assumptions you enter. Individual pages state limits such as no live data, no live rates, no billing-system connection, or no automatic advertising attribution where those limits apply.
