Free pricing and scoping tools built for freelance designers
Designer’s Toolkit by Domino Effect is a free, browser-based suite of business tools specifically designed for freelance designers. It addresses a common pain point: traditional business calculators often overlook the unique needs of creative professionals. The toolkit features 'Know Your Floor,' a powerful calculator that helps designers determine their true effective hourly rate by accounting for taxes, expenses, non-billable time, and profit margins. This ensures freelancers avoid undercharging and understand their real earning potential. Additionally, 'Scope Builder' enables designers to break down projects into manageable workstreams and tasks, empowering them to price projects accurately and confidently rather than relying on gut feelings. What sets this toolkit apart is its simplicity, zero cost, no sign-up requirement, and that it runs entirely within the browser, emphasizing privacy and ease of use. It’s an essential resource for freelance designers seeking to streamline their pricing strategies and project planning without any financial commitment.
