7Games

7Games is a utility toolkit where the percentage calculator is precise enough for professional use, covering margin, markup, percent change, and reverse-percent scenarios that come up in business every day.

Gross margin calculation is handled by Mode 2: enter revenue and cost, find what percentage the profit represents of the total, giving you a clear margin figure without needing a spreadsheet.

Percent change calculation (Mode 3) lets you compare two figures instantly: enter a starting value and an ending value to find exactly how much a number grew or shrank as a percentage, useful for sales reporting, analytics, and performance reviews.

The randomizer adds utility for team decisions and planning: use the decision mode to let 7Games pick from a list of options, shuffle a project task list, or generate a random number for any selection process.
