How to use it
- Enter the original amount.
- Enter the percentage.
- Read the three results displayed.
What it does – You input an original dollar amount and a percentage. The tool instantly shows three values: the monetary amount that the percentage represents, the new total if you add that amount, and the new total if you subtract it as a discount. Why it matters – Knowing the exact tip, tax, or discount helps you budget, price items accurately, and avoid rounding surprises. How to read – Percentage Amount is the dollar value of the entered percent. Total with Addition adds that value to the original amount. Total with Discount subtracts it. All results update as soon as you change a field, so you can experiment with different percentages without manual math. You can use it for restaurant tips, sales tax calculations, or pricing promotions. Because the calculator uses a straight‑line percentage rule, the math stays transparent and reliable. No hidden fees or complex settings—just pure numbers you can trust.
