Four calculators
Four calculators, each built to show the real numbers behind a credit decision, not just a single headline figure.
Credit utilization calculator
See your exact utilization ratio and what balance would bring you under common thresholds, plus the real payoff math if you're carrying a balance.
Assumptions this uses
- Utilization is calculated as current balance divided by credit limit
- Payoff math assumes the interest rate and payment stay constant every month
- Does not account for new charges added after this calculation
- Utilization is typically reported to bureaus once per statement cycle, not daily
Limitations: Does not reflect your overall utilization across multiple cards, or how your specific issuer times its reporting date.

Utilization is the fastest lever most people never pull
Unlike payment history, which takes months or years to rebuild, credit utilization can shift within a single billing cycle once a lower balance is reported to the bureaus. Paying a card down before the statement closing date, not just before the due date, is what actually moves the number. It won't undo years of missed payments, but it's the single fastest change most people can make.
Debt-to-income check
See the ratio lenders look at alongside your credit score before you spend time on a formal application.
Assumptions this uses
- Uses gross (pre-tax) monthly income as the denominator
- Adds housing payment and other debt payments together as total monthly obligations
- Does not include utilities, groceries or non-debt monthly expenses
- Compares your ratio against commonly used US lender thresholds, which vary by lender
Limitations: Actual lender thresholds vary by loan type, credit score band and individual lender underwriting policy.

The US Credit-Building Worksheet
A worksheet for tracking your utilization, disputes and rebuilding progress over time.
Get the free guide →Business credit readiness score
A quick check of how prepared your file looks before you apply for business credit, based on the basics most lenders check first.
Assumptions this uses
- Uses common, rough thresholds lenders often reference — 12 months trading, $5,000 monthly revenue, a 650 credit score
- Each factor is scored independently and does not represent any single lender's actual criteria
- Does not access your real credit file or verify anything you enter
Limitations: This is a readiness sketch, not a lender's decision — every lender scores business credit applications differently.

See real credit monitoring and building options
Once you understand what's driving your score, seeing your actual report and monitoring changes over time is the next honest step.
Compare monitoring options →Rewards vs. rebuilding card check
See whether a rewards card is actually worth it for you right now, or whether carrying a balance is quietly cancelling out any reward earned.
Assumptions this uses
- Rewards value is calculated as annual spend multiplied by the reward rate
- Assumes rewards are worth their stated percentage back, not a promotional bonus
- Any balance carried is flagged separately, since interest on a carried balance typically exceeds reward value
Limitations: Does not account for category bonuses, sign-up offers, or a specific issuer's redemption rules.
