An example of how a variable rate spring works:

Linear rate 12 inch spring – 130 lbs. per inch
Every inch of compression adds another 130 lbs.

1” = 130 lbs.
2” = 260 lbs.
3” = 390 lbs.

Variable rate 12 inch spring – 130 /250
In the same amount of travel, the spring rate picks up an additional 90 lbs. of resistance.
The spring gets progressively stiffer as it is compressed.

1” = 130 lbs.
2” = 290 lbs.
3” = 480 lbs.
