Best for: Anyone carrying a balance month-to-month

Credit Card APR Calculator

Turn your APR into real dollars per day, month, and year. See if your rate or your balance is the bigger problem — and what to do next.

Tip: A 1-point APR drop on a $5,000 balance saves roughly $50 a year — small APR moves matter more than people think.

Best for: Anyone curious what one billing cycle really costs

Credit Card Interest Calculator

See what your balance is really costing you this cycle, why — and the fastest way to lower it with ranked scenarios.

Tip: Two payments per cycle (mid-month and due date) almost always beats one — even if the total dollars are the same.

Best for: People juggling 2+ balances

Debt Payoff Planner

Enter your balances and APRs. See your debt-free date, total interest, and a month-by-month plan using snowball or avalanche.

Tip: Try both methods. Most planners pick avalanche; humans often finish snowball — because seeing a card hit $0 is fuel.

Credit Score Simulator

Test paying down a card, opening a new one, missing a payment, or closing an account. See an honest estimated score range.

Tip: Utilization is the fastest lever. Dropping a card from 80% used to 30% used can move a score in a single statement cycle.

Identity Exposure Score

A 3-minute assessment that scores your identity theft exposure, shows what's driving it, and gives you a prioritized action plan.

5 common credit mistakes these tools catch

  • Paying only on the due date

    Interest is charged on your average daily balance — not your statement balance. A second payment mid-cycle quietly cuts what you owe.

  • Closing your oldest card

    It usually hurts twice: average account age drops and total credit limit shrinks (utilization goes up).

  • Carrying a balance to 'build credit'

    A myth. Issuers report your statement balance — paying in full still builds credit and avoids interest.

  • Snowballing without checking APR

    If one card is 8% APR and another is 29%, snowball can cost hundreds extra. Run both methods in the planner first.

  • Paying for monitoring you don't need

    A free 3-bureau freeze blocks most new-account fraud at zero cost. Paid monitoring is worth it only in specific situations — the quiz tells you which.

Quick answers

  • Will using these tools affect my credit score?

    No. Everything here is educational. Nothing performs a hard inquiry, pulls your credit report, or reports anything to a bureau.
  • Do you store the numbers I type in?

    Calculators run locally in your browser. Inputs aren't sent to a server unless you explicitly download or email a result.
  • How accurate is the score simulator?

    It returns a range, not a single number. Real scores depend on data only the bureaus see, but the directional impact — up, down, and roughly how much — is reliable for decision-making.
  • Avalanche or snowball — which one should I use?

    Avalanche (highest APR first) saves the most money. Snowball (smallest balance first) keeps more people on the plan because early wins feel real. Run both in the planner and pick the one you'll actually finish.
  • Which tool should I start with if I'm not sure?

    Take the 2-minute quiz. It points you to the calculator or planner that matches your situation, so you're not guessing which number to crunch first.

Mini glossary

Six terms that come up across every tool. Skim once, then the calculators read like English.

APR (Annual Percentage Rate)
The yearly cost of borrowing on a card, expressed as a percentage. Daily interest ≈ balance × (APR ÷ 365). See it in the APR Calculator
Credit utilization
Statement balance ÷ credit limit. Below 30% is healthy; below 10% is ideal for score-sensitive moments like a mortgage application. Simulate a utilization change
Average daily balance
The figure issuers use to calculate interest — the average of your balance on each day of the billing cycle. Mid-cycle payments lower it. Run a cycle in the Interest Calculator
Hard inquiry
A credit check tied to a new credit application. Typically a small, temporary score dip (a few points) that fades within ~12 months. Estimate the score impact
Credit freeze
A free lock at each of the 3 bureaus that blocks new accounts from being opened in your name. Different from a fraud alert. See where freezes fit your plan
Grace period
The window between your statement date and due date when new purchases don't accrue interest — only if you paid the prior statement in full. Compare paid-in-full vs. carry scenarios
