FAQ – Percentage & Discount Calculator

Does this calculator include GST/Tax?

Yes. Toggle Add GST/Tax and enter the tax percentage. For final price, tax is added after discounts. For original price, it solves backwards if the sale price includes tax.

What’s the calculation order?

Percentage discount is applied first, then any extra fixed amount is subtracted. If tax is enabled, it’s applied on the discounted price.

Can I use decimals?

Yes. All fields accept decimals for precise pricing (e.g., 19.99, 7.5%).

Do you store my numbers?

No. Everything runs locally in your browser—nothing is uploaded or saved.

Conclusion

This free Percentage & Discount Calculator makes it easy to compute final price, discount percent, or original price with optional GST/Tax. Perfect for shopping sales, e-commerce pricing, and quick math checks.
