You have debt. The order that works.

Debt is not a moral failure. It is an interest rate problem. The question is not whether you should have taken on the debt. It is what to do with it now. The answer depends on the rate, the type, and what else is competing for the same dollar.

This page covers personal finance fundamentals that apply regardless of your view on Bitcoin or fiat currency.

This page covers US-specific debt types and tax law. Outside the US? The principle (interest rate determines priority) is universal; the specific debt categories differ.

THE SHORT VERSION

Credit card debt at 21%: pay it before you do almost anything else. Student loans at 4%: invest alongside payoff. Avalanche method saves the most money. Snowball method keeps you motivated. Use whichever you'll actually stick to. The biggest mistake is ignoring the math entirely; the second biggest is letting one type of debt stop you from contributing to your 401k up to the match.

1 · THE LANDSCAPE

Debt types: which to attack and which to ignore

Credit card vs student loan vs car vs mortgage vs medical. Each behaves differently. Treating them the same is the most common mistake.

2 · THE FRAMEWORK

The order of operations

When to invest vs when to pay down debt. The interest rate threshold above which guaranteed payoff beats expected market return.

3 · THE FOUNDATION

Zero to One

The starter financial checklist. Get to a small emergency fund first so the next surprise expense doesn't add to the debt.

Common questions

Should I invest or pay off debt first?

Guaranteed return: your interest rate. Credit card at 21%: pay it first because nothing in markets reliably beats that. Student loans at 4%: invest alongside payoff and capture the 401k match. Order of operations →

Avalanche or snowball method?

Avalanche (highest interest first) saves more money. Snowball (smallest balance first) creates faster wins that keep you motivated. The best method is the one you'll stick to for the full payoff window. Run both side-by-side →

Should I consolidate my credit card debt?

A 0% balance transfer or personal loan at a lower rate can save significant interest, if you don't accumulate new debt while paying off the old balance. The behavioral piece is harder than the math. Debt types →

Should I keep contributing to my 401k while paying off debt?

Up to the employer match: yes, always. The match is an instant 50-100% return. Above the match: depends on the debt rate. 401k match optimizer →
