Frequently Asked Questions
Are these tools really free?
Yes. All six calculators are completely free to use with no signup required. They run entirely in your browser.
How accurate is the Credit Score Simulator?
The simulator uses industry-standard FICO® weighting models to estimate score changes. Real results vary by bureau and lender.
Which debt payoff strategy is better-snowball or avalanche?
The avalanche method (highest APR first) saves the most in interest. The snowball method (smallest balance first) provides faster psychological wins. Our Debt Payoff Visualizer lets you compare both side-by-side.
Can I use these tools on mobile?
All tools are fully responsive and work on any device-phone, tablet, or desktop.
