20% of 1500 is 300. Fifteen hundred divides cleanly by five, so the one-fifth rule lands on a round integer: 1500 ÷ 5 = 300. That is the number to book when 1500 is your cap—rental deposits, small-fleet mileage pools, rounded campaign spends, or any line where “twenty points” is the share you must quote.
If you like tens: 10% of 1500 is 150, and doubling gives 300. For a lower rate on the same base, 15% of 1500 is 225; moving from fifteen to twenty adds 75 to the slice—another way to sense-check a table without restarting from scratch.
“20% off” on £1500 means £300 off and a promotional subtotal of £1200 before other charges—a neat echo of 20% of 1200 being 240, but here 1200 is the remainder, not the twenty-percent portion. If the question was only “what is 20% of 1500,” the answer stays 300.
What follows keeps language tied to 1500, 20%, and 300 so you can audit a single row or teach the method without boilerplate.
One fifth of 1500 is 300. On the same twenty-percent rate, 20% of 1250 is 250—two hundred fifty more in the base adds fifty to the fifth.

Formula used: (percentage ÷ 100) × number
Method A (one fifth): 1500 ÷ 5 = 300.
Method B (decimal): 0.20 × 1500 = 300.
Method C (from 10%): 150 × 2 = 300.
Full formula: (20 ÷ 100) × 1500 = 300. A structural view: fifteen hundreds each contribute 20 at a 20% rate, and 15 × 20 = 300, matching the fifth. For a higher neighbour on the same base, 25% of 1500 is 375—a quarter instead of a fifth.
The ratio 300 : 1500 simplifies to 1 : 5, so the twenty-percent line item is exactly one part in five of the whole. That is easy to sketch on a bar or pie chart when you are explaining a fee, a discount, or a reserve to someone who does not live in spreadsheet notation.
Scale check: twenty percent of 3000 is 600; halving both base and portion returns 1500 and 300. If your model doubled by mistake, that pair of halvings brings you back to this page’s numbers.

All three are integer-only here, which helps when you are comparing a mental estimate to a till, a quote, or a column total.
Example 1: 20% discount on a £1500 sofa
The saving is £300 and the sale price before delivery is £1200.
Example 2: 20% of a £1500 quarterly tooling budget
Twenty percent of the cap is £300, leaving £1200 for other lines if the pool stays fixed at 1500.
Example 3: Fee on a payment of 1500
A 20% service fee on 1500 takes 300; the balance after removing only that fee is 1200.
Example 4: Time from 1500 minutes
Twenty percent of 1500 minutes is 300 minutes—five hours carved from a twenty-five-hour style block (1500 min = 25 h).
20% of 1500 is 300.
Divide 1500 by 5 to get 300, multiply 1500 by 0.20, or double 10% of 1500 (150 + 150).
20% off 1500 is a reduction of 300, leaving a final amount of 1200.
