This app calculates credit utilization using current credit card balance and limit. Users may add up to 5 credit cards by clicking the '+card' button. When all information has been added, the total and individual credit usages are calculated. Individual credit usage is the the percent usage for a single card, while total credit usage is percentage usage across all credit cards
Credit utilizations greater than 30% will be displayed in red text, since this is the recommended max.
The calculations are derived with the following formulas:
Individual:
(balance * 100) / limit
Total:
(total balance * 100) / total limit
EXAMPLE:
card 1 - balance: 100, limit: 1000
card 2 - balance: 200, limit: 2400
card 3 - balance: 300, limit: 4000
card 1 usage: (100 * 100) / 1000 = 10.00%
card 2 usage: (200 * 100) / 2400 = 8.33%
card 3 usage: (300 * 100) / 4000 = 7.50%
total usage: [(100 + 200 + 300) * 100] / (1000 + 2400 + 4000) = 8.11%
