About PercentLab: Percent Calculator
Calculate percentages, discounts, increases and tax on one screen. Core calculations and comparisons are free with PercentLab. A 20% discount on 1,000 means a final price of 800. See the discount amount and the final price together, without repeating the calculation. FREE CALCULATION TOOLS • Find any percentage of an amount. • Add or subtract a percentage to see the final value. • Calculate prices including and excluding tax at your chosen rate (shown as VAT in the app). • Compare two values: find the percentage change or what percent one is of the other. • Customize your quick percentage buttons in Settings. • Copy or share a result and revisit recent calculations. ENGLISH AND TURKISH PercentLab follows your phone’s supported language when you first open it. Switch between English and Turkish using the flag button in Settings. Number formats, calculation history and reports adapt to your selected language. DO MORE WITH PERCENTLAB PREMIUM • Sequential calculations: Apply up to 10 steps to one amount. A 20% discount followed by 10% is a total discount of 28%—see each step clearly. • Batch calculations: Paste up to 200 amounts, apply the same percentage operation to every line and see the grand total. • Currency tools: Convert between TRY, USD, EUR, GBP and JPY and view exchange rates. • Unlimited calculation history. • Export calculations as PDF or CSV. Core calculations are free. Premium tools require a one-time in-app purchase. Your local price is shown on the purchase screen. Restore a previous purchase using Restore Purchases in Settings. Refreshing exchange rates requires an internet connection. Currency conversions are for reference and are not bank or transaction quotes. You set the VAT rate yourself. Enter an amount. Choose a rate. Get your answer. Support: [email protected]
