How VAT and the senior citizen discount work
Most prices in the Philippines include 12% VAT. To find the price before VAT, divide by 1.12. To add VAT to a price, multiply by 1.12. These simple steps are useful for shoppers checking a receipt and for small businesses preparing invoices.
Senior citizens and persons with disability get a 20% discount and VAT exemption on qualified purchases. The discount is applied to the price after VAT is removed, so the saving is bigger than a plain 20% off. This calculator shows the exact amount, so you know what to expect at the counter.

How the VAT and discount math works
- Add VAT: VAT equals the price times 12%. The price with VAT is the price times 1.12.
- Remove VAT: the price without VAT is the price divided by 1.12. VAT is the difference.
- Senior and PWD discount: the price with VAT is first divided by 1.12 to remove VAT, then 20% is deducted from that VAT-free amount, so you pay less than a simple 20% off.
- Discounts apply to qualified items and purchases under the law, usually with a valid ID. Stores can have limits, so ask at the counter.
Tips to save more
- Bring a valid senior or PWD ID and ask which items qualify.
- Compare the discount with any active store promo, since you may not be able to combine them.
- For business invoices, keep VAT and non-VAT amounts clearly separated.
- Use the calculator to double-check a receipt if a total looks off.
