Simulate a Credit Move
Choose a scenario, adjust the inputs, and see projected score changes before you take action.
We model score changes using a simplified FICO-style algorithm. Real bureaus may weigh factors differently. Use this as a planning tool, not a guarantee.
How to Use These Insights
These best practices help you turn simulator projections into real-world score improvements.
Build a 30-60-90 Day Plan
- • Focus first on utilization below 30%, then below 10%.
- • Set autopay to avoid new late payments—payment history is 35% of your score.
- • Space applications at least 6 months apart to protect the “New Credit” factor.
Before You Apply for Credit
- • Run scenarios for paying balances down before a mortgage or auto loan.
- • Keep your oldest accounts open unless the fees outweigh the score hit.
- • Track changes monthly—scores update as lenders report new balances and payments.
Disclaimer: This simulator uses industry-standard weighting to show likely score changes. Actual scores may differ based on bureau, scoring model, and the rest of your credit profile.
How This Simulator Works
We mirror FICO-style weighting: payment history (35%), credit utilization (30%), length of history (15%), new credit (10%), and credit mix (10%). Each simulation recalculates those components and projects a score range so you can make informed decisions before you apply, close, or miss a payment.
Plan Moves Before Major Applications
Run a pay-down scenario before applying for a mortgage or auto loan to see if dropping utilization pushes you into a higher tier.
Avoid Unexpected Score Damage
Closing your oldest card or missing a payment can erase years of progress. The simulator shows you the likely hit before it happens.
Stack Smarter Credit Strategies
Combine actions—like paying down debt and requesting a limit increase—to test which sequence gives you the biggest boost with the least risk.
Best Practices Before You Take Action
- Pull your latest credit report so balances, limits, and late payments are up to date.
- Adjust scenarios for real-world assumptions (e.g., statement dates, credit limit approvals, lender reporting timelines).
- Log the results and revisit them after lenders report changes to compare projections against reality.
