It's simple. You get a multiplier on the cash you make from kills.

Every two kills in a killstreak = 0.1+ multiplier.

This means,

After two kills in a row, your cash income is 1.1x.

After four kills, your income is 1.2x

After eight kills, your income is 1.4x

After twenty kills, your income is 2x.

After forty kills, your income is 3x.

So on, and the increment goes up every two kills. 10 seconds after your killstreak ends, the cash income is reset to 1x.

After all, there really is no point to killstreaks in zombie gamemodes. This would make killstreaks a fun challenge as well as a good grinding method.
