How to Get the Most Accurate Results
While our calculators are built to be highly accurate, the quality of the output depends on the quality of the input. Follow these three simple rules to ensure you get the best possible results:
- Double-check your inputs: A misplaced decimal point or an extra zero can drastically change the result. Take a second to verify your numbers before hitting calculate.
- Understand the context: For example, when using the PAYE calculator, ensure you are entering your gross salary, not your net salary. When using the profit calculator, make sure you have included all hidden operating expenses, not just the cost of goods.
- Use the breakdown tables: Every calculator on our site provides a detailed breakdown of how the final number was reached. Review this section to understand the math and catch any potential errors.
