About

Rahmi Multi Calculator is a modern all-in-one calculator extension for Google Chrome, designed to make everyday calculations faster, easier, and more organized. Instead of opening different websites, searching for formulas, or switching between multiple apps, you can use one clean browser extension for many useful calculation tasks directly inside Chrome.

Rahmi Multi Calculator is built for users who want a simple but powerful calculator tool for daily work, shopping, business planning, study, finance, online selling, app development, and general productivity. The extension includes a normal calculator as well as several smart calculation tools such as VAT calculation, percentage calculation, currency conversion with manual exchange rates, unit conversion, finance calculation, discount calculation, tip calculation, and app revenue estimation.

The extension is designed with a clean and modern interface. It supports both English and German. On first start, users can choose their preferred language. After that, the extension shows a short introduction and then opens the main calculator area. This makes the first experience easy to understand, even for users who are not familiar with advanced calculator tools.

Rahmi Multi Calculator includes a standard calculator for basic math operations such as addition, subtraction, multiplication, and division. It is useful for quick calculations while browsing, shopping, working, or comparing prices. The calculator is designed to be fast and clear, with large buttons and a readable result display.

The VAT calculator helps users calculate net amounts, gross amounts, and VAT values. This is useful for invoices, business planning, online selling, taxes, pricing products, or checking how much tax is included in a price. Users can work with different VAT rates and also set a default VAT value in the settings.

The percentage calculator helps with common percentage tasks. Users can calculate a percentage of a value, compare old and new values, and understand percentage changes. This is useful for discounts, price increases, business growth, statistics, finance, and everyday comparisons.

The currency calculator is an offline converter with a manually editable exchange rate. This means the extension does not require an internet connection or external service to work. Users can enter the amount, choose currencies, and adjust the rate whenever they need current market values. This is helpful for quick travel, shopping, international pricing, or business estimates.

The unit converter supports useful everyday conversions such as length, weight, temperature, and data units. Users can quickly convert values without opening another website. This is helpful for students, developers, office users, travelers, and anyone who often works with different measurement systems.

The finance calculator helps with savings and loan-style calculations. Users can estimate values such as savings growth, monthly deposits, interest, loan payments, and total interest. It is useful for planning, comparing financial options, and getting quick estimates directly in the browser.

The discount calculator helps users calculate sale prices and savings. Enter the original price and discount percentage to quickly see the final price and how much money is saved. This is useful for shopping, online stores, deals, promotions, and price comparisons.

The tip calculator helps calculate the total bill, tip amount, and amount per person. It is useful when splitting a bill with friends, family, or colleagues. Users can enter the bill amount, tip percentage, and number of people.

The app revenue calculator is especially useful for developers, creators, and online sellers. It helps estimate net revenue after platform fees, payment fees, fixed fees, and taxes. This is helpful for planning digital products, browser extensions, apps, small tools, and online sales. It gives a quick overview of fees and estimated net earnings.

Rahmi Multi Calculator also includes a history feature. Calculations can be saved in a clear history area so users can review recent results. The history can be opened as a popup and cleared when needed. Users can also decide in the settings whether history should be saved.

The extension includes several settings to customize the experience. Users can change the language between English and German, select Dark Mode, White Mode, or System Mode, choose the default VAT rate, set decimal places, choose the decimal separator, enable or disable the copy result button, enable or disable history saving, and use compact mode. These settings help users adapt the extension to their own workflow.

Rahmi Multi Calculator is designed to work offline. It does not need an account, login, subscription, or external server. The extension does not show ads and does not include tracking features. It only uses local storage to save user preferences and history. This keeps the extension simple, private, and lightweight.

The design is optimized for quick use inside the Chrome browser. The interface uses modern colors, clean buttons, a blue gradient style, clear sections, and a simple tab navigation system. Users can switch between calculator tools easily and scroll through the available tools with the navigation arrows.

Rahmi Multi Calculator is useful for many types of users: office workers, students, freelancers, developers, online sellers, business owners, shoppers, travelers, and anyone who wants a practical calculator directly inside Chrome. It combines multiple useful calculators into one extension, reducing the need to search online for separate calculators.
