The Budget Builder Pro Calculator is an all-in-one budgeting tool designed for business owners and nonprofit directors. This app includes three calculators: Income Calculator: Estimate the annual revenue needed to meet your desired salary. Nonprofit Budget Calculator: Create a foundation budget based on revenue from the first calculator or your own estimate. Federal Budget Calculator: Generate a budget with typical government agency percentages. Simply enter a starting amount, and the app will automatically fill in estimates for each calculator. You can also adjust values to explore different budget scenarios, making it easy to plan for grants, contracts, or loan applications.
