20% of 1200 is 240. With this base, twenty points out of a hundred pick off exactly one fifth of the total, and 1200 ÷ 5 = 240 with no trailing decimals. That makes the pair easy to audit on invoices, roster plans, or any line where “1200” is the cap and “20%” is the slice you need to quote. If you already know 10% of 1200 is 120, doubling gives 240—a second route that never leaves the integers on this page.
When a label says “20% off” on £1200, the reduction is £240 and you would typically pay £960 before any further taxes or fees. Stating only the portion (240) is correct when the question is strictly “what is 20% of 1200,” so keep the final total separate unless someone asked for the discounted price.
Everything below stays on 1200, 20%, and 240 so you can skim for the method you prefer—fifth, decimal, or cross-check against ten percent—without generic percentage lectures.
One fifth of 1200 is 240. For a smaller round base on the same rate, 20% of 1000 is 200; scaling up to twelve hundred adds 40 to that fifth.

Formula used: (percentage ÷ 100) × number
Method A (one fifth): Because 20% = 1/5, divide 1200 by 5: 1200 ÷ 5 = 240.
Method B (decimal): Write 20% as 0.20, then 0.20 × 1200 = 240.
Method C (from 10%): Ten percent of 1200 is 120; twenty percent is twice that: 120 × 2 = 240.
Full formula: (20 ÷ 100) × 1200 = 240. All three paths land on the same integer, which is handy when you are sanity-checking a sheet where someone might have used a different route. If you are comparing rates on the same twelve hundred, 15% of 1200 is 180 and 25% of 1200 is 300—so 240 sits between those two slices.
Twelve hundred breaks evenly by five, so the “20% = one fifth” story never forces rounding here. In operational terms, that means a 20% line item on a 1200 budget is exactly 240 units of whatever you are counting—pounds, hours, seats, or clicks—without a fuzzy tail.
The ratio 240 : 1200 simplifies to 1 : 5, which is the same as saying “for every five parts of the whole, one part is the twenty-percent share.” That framing helps when you are explaining a fee or allocation to someone who thinks in fractions more easily than in percent labels.
Whenever you see 20% of a number, ask whether the base divides cleanly by 5. For 1200, the mental line is short:
If the base were awkward, you could still use 10% then double; here that means 120 × 2 = 240, matching the fifth. Either shortcut is faster than reaching for a calculator when you only need a confidence check.
Example 1: 20% discount on a £1200 laptop
The saving is £240 and the promotional price before other charges is £960.
Example 2: 20% of a £1200 quarterly marketing cap
Testing spend at twenty percent of the cap is £240, leaving £960 for the rest of the quarter if the limit stays fixed at 1200.
Example 3: Fee on a payment of 1200
A 20% service fee on an amount of 1200 takes 240, so the remainder after removing only that fee is 960.
Example 4: Time from a 1200-minute block
Twenty percent of 1200 minutes is 240 minutes—four hours carved from a twenty-hour style total.
20% of 1200 is 240.
Divide 1200 by 5 to get 240, or multiply 1200 by 0.20, or double 10% of 1200 (120 + 120).
20% off 1200 is a reduction of 240, leaving a final amount of 960.
