Compare the same basket in Singapore dollars: item price plus delivery minus confirmed discounts equals the checkout payment. No live rate is supplied by this calculator.
Compare two checkouts
This calculator needs JavaScript. To compare by hand, add item price and delivery, then subtract confirmed discounts to get each checkout total. Treat any Cashback as a separate, later and uncertain amount.
How to compare two checkouts
Enter the total item price for each equivalent basket, including applicable taxes and mandatory fees, then delivery and only discounts you have confirmed at checkout. Use SGD throughout; this tool does not convert currencies. Do not subtract a sale reduction twice if it is already reflected in the item price. Include other mandatory charges in the item total, or the comparison will understate your payment.
Checkout payment = item price + delivery - confirmed discounts. The lower checkout payment determines the immediate-price comparison. If you choose to enter an estimated Cashback amount, estimated cost after Cashback = checkout payment - estimated Cashback. Only compare the two conditional costs when you have entered estimates for both options.
Enter amounts from 0 to 999999.99 with at most two decimal places, without currency symbols or commas. Discounts cannot exceed item price plus delivery. An estimate cannot exceed the checkout payment. The calculator rounds no user inputs: it calculates in whole cents.
Hypothetical SGD example, not a current offer
Option A: SGD100.00 of items + SGD5.00 delivery - SGD10.00 confirmed discount = SGD95.00 paid at checkout. Option B: SGD98.00 of items + SGD0.00 delivery - SGD0.00 discount = SGD98.00 paid at checkout. Option A costs SGD3.00 less immediately.
B would be SGD1.00 lower only if both estimates were awarded in full. Those invented estimates are not rates, verified offers or promises. The payments due today are still SGD95.00 and SGD98.00.
