This page is a % off calculator in table form: the most-searched percent-off sums answered outright, then the full grid — 5% to 75% off every common price from $10 to $500 — with every cell computed from the one formula, never typed from memory.

The quick answers

Most percent-off searches are a single sum. Here are the ones asked for most, each answered with both halves of the result — what you save and what you pay:

Every row computed from the one formula: saving = price × rate, you pay = price − saving. Rows are in the order the sums are searched, most-searched first.

How much is 20% off — of anything at all?

Two questions hide inside that search. How much is 20% off as a rule: a fifth of the price comes off, so you pay 80% of it. How much is 20% off $75 in particular: $15.00 off, you pay $60.00 — the grid’s $75 row, 20% column. And how much is 10% off: a tenth comes off and you pay 90% — on $45 that is $4.50 off and $40.50 to pay. Any price follows the same shape: the percent names the slice removed, and the rest of the table is that sentence repeated at other prices.

The full percent-off table

Each cell is the price you pay. The saving on any cell is the row price minus the cell.

Read across a row to compare every percent against one price; read down a column to watch one percent work on every price. The two directions teach different things. Across the $100 row you can see the percents as pure numbers — at p% off $100 you pay $(100 − p), which is why the $100 row is the one to memorise. Down the 50% column, every price simply halves, doubling as a check on the whole table: if any other cell surprises you, its row’s 50% cell will usually show you where the arithmetic went.

Reading a price that is not in the table

Tables have edges; arithmetic does not. A price between two rows can be reached by scaling: 20% off $35 is half of 20% off $70, and since the $70-scale answer is $56.00 paid on the doubled price, the $35 tag costs $28.00. A percent between two columns can be reached by the midpoint: 15% off $60 sits halfway between the 10% cell ($54.00) and the 20% cell ($48.00), at $51.00. And a price above the table doubles out of it the same way — 30% off $600 is twice the $300 row’s 30% cell ($210.00), so $420.00. The table is a ladder, not a fence.

The columns, band by band

The eleven columns are not evenly spaced, because retail percents are not either. The 5% to 15% columns are the token bands — loyalty offers, first-order nudges, the small print of a promotion — where the honest question is usually whether the discount survives the delivery fee. The 20% and 25% columns are the standard sale, the depth at which most seasonal events actually run. 30% and 40% are serious reductions, the point where checking the arithmetic starts to pay real money: at 40% off, a $10 error in the tag’s favour is a common size of mistake. And 50% to 75% is clearance arithmetic, where the useful skill flips — at those depths the question is less what you save than what you pay, which is why this table prints the payment, not the saving, in every cell.

Stacked sales, measured against the table

The table also exposes the oldest trick in the sale calendar: the stacked headline. A rail marked “30% off, plus an extra 10% off” invites you to read the 40% column. Do not. The stack runs in sequence — on $120, 30% off leaves $84.00 and the extra 10% leaves $75.60 — while the table’s honest 40% cell for $120 is $72.00. The $3.60 gap between the stacked event and the single discount it impersonates is exactly the ground the headline was designed to blur, and it is visible at a glance once both numbers are on the page.

How every cell was checked

A reference table is only worth printing if its cells can be trusted, so each one here was computed twice by independent routes — once from the formula saving = price × rate, and once through the Discount Calculator’s own engine, the same code that answers the sums at the top of the hub page. Where a percent produces fractions of a cent, the convention is the register’s: the price you pay is rounded to the nearest cent, and the saving shown is the remainder, so the two halves of every answer always add back to the tag price exactly — 40% off $16.99 is a $10.19 payment and a $6.80 saving, and $10.19 + $6.80 is $16.99 to the cent.

Before tax, always

Every price in this table is the discounted price before sales tax, because that is the order the register uses: the discount comes off, then tax is charged on what remains. To turn any cell into an out-the-door total, take the cell price to a sales tax calculation at your local rate — the companion guide on discount and tax order works the full receipts. The table’s job is the first step only, and it does that step for five hundred prices so that you do not have to. One cell carried through, by way of example: the 30% cell on the $90 row is $63.00; at an 8.25% tax rate the tax on it is $5.20, and the register total is $68.20 — the discount’s work done by the table, the tax’s work done after it, in that order.
