- Final price paid — a money amount. Example: ₹1,500.
How to calculate it step by step
- Write down the original price (for example, ₹2,000).
- Write down the final price paid (for example, ₹1,500).
- Apply the formula above to get your discount.

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
