Debt repayment isn't just about writing checks—it's about understanding the time value of money and how interest compounds against you when you're the borrower instead of the investor. You're being tested on your ability to analyze different repayment strategies, calculate their true costs, and recommend the right approach for different financial situations. The concepts here connect directly to interest rate calculations, opportunity cost, behavioral finance, and credit management.
Every method in this guide represents a trade-off between mathematical optimization and psychological motivation. Some strategies minimize total interest paid; others maximize your likelihood of actually sticking with the plan. Don't just memorize what each method does—know why someone would choose one over another and what financial principle each strategy leverages.
These methods prioritize minimizing the total cost of debt by targeting high-interest balances first. The underlying principle is simple: every dollar of interest you don't pay is a dollar that stays in your pocket.
Compare: Debt Avalanche vs. Debt Acceleration—both focus on reducing interest costs, but avalanche is about sequencing (which debt first) while acceleration is about intensity (how much per payment). An FRQ might ask you to calculate interest savings from either approach.
Behavioral finance research shows that motivation matters as much as math. These methods leverage quick wins and emotional momentum to keep you engaged in the repayment process.
Compare: Debt Snowball vs. Debt Stacking—both prioritize psychology over pure math, but snowball uses an objective metric (balance size) while stacking is entirely subjective. Know when to recommend each: snowball for someone who needs clear rules, stacking for someone with emotionally charged debts.
These methods change the terms of your debt rather than just the payment order. They work by negotiating new rates, combining balances, or settling for less than owed.
Compare: Debt Consolidation vs. Balance Transfer—both restructure existing debt, but consolidation creates a new installment loan while balance transfers keep debt on revolving credit. Balance transfers work best for credit card debt you can eliminate within the promo period; consolidation suits larger, longer-term debt reduction.
When debt becomes unmanageable, outside help can provide structure, negotiation power, or settlement options. These methods involve working with credit counselors or creditors directly.
Compare: Debt Management Plans vs. Debt Settlement—DMPs pay creditors in full over time with reduced interest, preserving more of your credit; settlement pays less but destroys your credit score and may trigger taxes. DMPs suit people who can afford reduced payments; settlement is a last resort before bankruptcy.
Understanding the default approach helps you see why active strategies matter.

Which two methods prioritize mathematical optimization over psychological motivation, and what principle do they share?
A client has five credit cards with balances ranging from to and interest rates from 12% to 24%. They've tried budgeting before but always quit after a few months. Which repayment method would you recommend and why?
Compare and contrast debt consolidation and balance transfers: what type of borrower benefits most from each, and what risks does each carry?
Why might debt settlement result in a tax bill, and how does this connect to the IRS definition of income?
An FRQ asks you to calculate the total interest paid under the minimum payment method versus the debt avalanche method for the same debt load. What variables would you need, and which method would show lower total cost?
