Although at first it might seem like a random arrangement of numbers, if you look closer you will see a pattern emerging in the numbers after 100. They increase roughly by 10% each time and the pattern repeats itself as more zeros are added:

  • Anything beginning with a one (100, 1,000, 10,000 etc.) goes up in ‘1s’ (100 – 110 - 120 or 13,000 - 14,000 - 15,000 etc.)

  • Anything beginning with a two (200, 2,000, 20,000) goes up in ‘2s’ (200 – 220 – 240 – 260 or 2,400 – 2,600 – 2,800)

  • Anything beginning with three or a four (300, 400, 3,000, 4,000) goes up in ‘0 - 2 – 5 – 8’ (300 – 320 – 350 – 380 or 4,000 – 4,200 – 4,500 – 4,800)

  • From then on, between five and nine the numbers go up in ‘5s’ (500 – 550 – 600 – 650 or 7,000 – 7,500 – 8,000 – 8,500)

  • After that, it is back to one and the pattern repeats itself. 

These are the standard bidding increments that are adopted by most auction houses across the world – a universal auction language.

Needless to say, you don’t need to know the increments by heart when bidding. The bidding dropdown on the auction and lot pages will always display the next 40 increments.
