Multiply the payment amount by the fee percentage divided by 100. For example, a 3% fee on $500 is calculated as $500 × (3 / 100) = $15.00 fee (Total: $515.00).
Divide the portion amount by the total dollar amount and multiply by 100. For example, to find what percent $25 is of $200: ($25 / $200) × 100 = 12.5%.
Multiply the total dollar amount ($Y) by (X / 100). For example, 15% of $80 is (15 / 100) × $80 = $12.00.
Discounted price = Original price × (1 - discount%/100). A 20% discount on $100 = $100 × 0.80 = $80.00.
