About this app
ProCalc.app brings professional business calculators into one fast, focused app: margin rate, break-even point, fees/commissions and Mini Business Plan. Price products, services and offers with a clearer view of costs, VAT/sales tax, discounts, payment fees, marketplace commissions, freelance platform fees, margins and profitability. Whether you sell online, run a shop, freelance, consult or test a new offer, ProCalc.app helps you answer the question that matters: is this price actually profitable? ■ MINI BUSINESS PLAN Turn saved calculations into a monthly profitability snapshot. Import a fee, margin or break-even scenario, add expected monthly sales and a profit target, then get a clear summary: monthly revenue, cost of goods, total fees, profit, break-even sales, required price and gap to target. ■ SAVED SCENARIOS AND COMPARISONS Save a calculation for a product, client, offer or sales channel. Compare two scenarios side by side, see which one wins on the key metric, and update a loaded scenario after changes instead of creating duplicates. ■ CHARTS AND EXPORTS Visualize costs, margins, fees, fixed costs and profit with simple business charts. Export a clean PDF report and CSV file to share with a partner, accountant, client or team. ■ MARGIN CALCULATOR Enter purchase cost, target margin, markup, coefficient, sale price, tax or discount. ProCalc.app instantly calculates sale prices before/after tax, discounted price, margin rate, markup rate and coefficient. ■ BREAK-EVEN CALCULATOR Estimate when an activity becomes profitable. Add units sold, sale price, variable costs, fixed costs and period to calculate break-even value, break-even units, result and time to profitability. ■ FEES, MARKETPLACES AND FREELANCE Know your real profit after fees. Calculate payment fees, shipping, taxes, platform commissions and profit after costs. Use adjustable templates for PayPal, Stripe, Amazon, Etsy, eBay, Shopify, WooCommerce, Square, SumUp, Mercado Pago, Klarna, TikTok Shop, ComeUp, Fiverr, Malt, Upwork and more. ■ TARGET DIAGNOSTICS A margin number is useful; knowing whether it is healthy is better. ProCalc.app highlights whether a scenario is healthy, needs attention or is risky based on your target. ProCalc.app is built for entrepreneurs, shop owners, freelancers, makers, consultants and small teams who need professional pricing decisions without rebuilding spreadsheets. Download ProCalc.app and make better pricing decisions in seconds.
