See the Numbers for Yourself
In the book, I break down exactly what bad credit costs you—and what good financial decisions can build over time. These calculators let you plug in your own numbers and see it for yourself. Because the decisions you make about money right now will echo for decades. Make them count.
Book example: The Monetary Success chapter compares a $25,000 car loan over five years at 4% and 13%. Start with those numbers, then replace them with a real offer you are considering.
What this includes: vehicle price, down payment, principal, and loan interest. It does not include sales tax, title or dealer fees, insurance, fuel, maintenance, or repairs.
This is amortization. The interest share is highest early because the amount you still owe is highest. As the balance falls, more of each payment goes to principal.
Book example: The Monetary Success chapter compares a $150,000, 30-year home loan at 5% and 8.5%. Use the same starting numbers here, then replace them with an actual Loan Estimate.
What this includes: purchase price, down payment, principal, and loan interest. It does not include property tax, homeowners insurance, mortgage insurance, HOA dues, closing costs, utilities, or maintenance.
On a long mortgage, total interest can be very large. The interest share starts highest because the balance is highest, then falls as principal is repaid. Compare the full Loan Estimates, not only the monthly payment.
The book’s lesson is simple: small decisions can compound over time. This tool shows one hypothetical path so you can see why starting early matters.
Remember: this is a hypothetical future-dollar estimate before inflation, taxes, and investment fees. Returns are not guaranteed.
The book points readers to a Credit Score Estimator. This safer website checkup teaches the habits that may influence a score, but it cannot calculate or predict your actual credit score.
