Interest & credit calculators
Interest & credit calculators — 2 tools, each showing the formula it uses, the source that published it, and the date that source was last checked.
Credit Utilization
Enter each card's balance and limit to get utilization per card and across all cards, plus the exact paydown that brings your overall ratio to a target like 30%. Education only: it computes the ratio the CFPB's guidance describes, and it never pretends to simulate your score.
Daily Interest
What a balance costs per day: the daily periodic rate, the dollars of interest each day adds, and the total over any number of days. The per-day figure is the most motivating number in debt math — it turns an abstract APR into what this morning cost.
