Common Pitfalls & Mistakes to Avoid
Inputting Incorrect Units or Unmatched Intervals
Always verify that all input values use consistent units (e.g. converting percentages to decimals or matching annual vs. monthly rate periods) before computing.
Neglecting Order of Operations (PEMDAS/BODMAS)
When performing manual checks, calculate operations inside parentheses first, followed by exponents, multiplication/division, and finally addition/subtraction.
Rounding Intermediate Values Too Early
Keep full floating-point precision throughout intermediate calculation steps. Only round the final answer to your desired decimal accuracy.
