About Calculator Workshop
A growing collection of practical online calculators designed to make everyday calculations quick and simple.
Simple Tools for Everyday Use
Calculator Workshop was created as part of the CS17 Tools collection to bring commonly used calculators together in one easy-to-use website.
Instead of searching for a different website every time you need to calculate a percentage, loan repayment, business margin or unit conversion, Calculator Workshop provides these tools in one place.
What You Can Calculate
Calculator Workshop includes a range of everyday, finance, business and conversion tools.
Standard Calculator
Everyday addition, subtraction, multiplication, division and percentage calculations.
Tax & Percentage
Australian GST, US state sales-tax tools and common percentage calculations.
Finance
Loan repayments, mortgages, compound interest and savings-goal calculations.
Business
Markup, margin, discounts, profit and break-even calculations.
Conversions
Convert between common metric, Imperial, US and technical units.
More Tools Coming
Calculator Workshop will continue to grow with additional useful calculators and utilities.
Designed to Be Simple
The goal of Calculator Workshop is straightforward: provide useful calculators without making them complicated.
The interface is designed to work across desktop computers, tablets and mobile phones, with calculations updating quickly as values are entered.
Easy to use
Clear inputs and results without unnecessary steps.
Works in your browser
No software installation is required.
Mobile friendly
Designed to work on phones, tablets and computers.
Continuously improving
New calculators and improvements can be added over time.
Tax Calculators
Calculator Workshop includes country-aware tax tools. Australian users can calculate GST, while United States users can select a state and calculate state and local sales tax.
US state sales-tax information is designed to be checked periodically so the calculator can continue using current state-level rates where possible.
Calculator Results
Calculator Workshop is intended to help with general calculations, comparisons and estimates.
Finance, mortgage, investment and business calculations can be affected by lender rules, fees, taxes, compounding methods, accounting treatment and other factors not included in a simple calculator.
Results should therefore be used as a guide rather than as financial, accounting, tax, legal or other professional advice.
CS17 Tools
Calculator Workshop is part of CS17 Tools, a growing collection of useful online tools designed to solve everyday problems quickly.
The CS17 collection includes word and puzzle tools, crossword tools and other web-based utilities, with more tools planned for the future.

Calculator Workshop will continue to be expanded with new calculators, conversions and useful everyday tools.
