Debt Payoff Optimizer
Snowball vs avalanche is usually presented as a binary choice. This runs a real month-by-month simulation of both — plus a documented blended strategy — against your actual debts, so you can see the real interest and time tradeoffs instead of picking a strategy on faith.

Debt Snowball vs Avalanche
Avalanche minimizes total interest by always targeting your highest APR first. Snowball targets your smallest balance first, trading some interest efficiency for faster early payoffs and momentum.
How the Miser Optimized strategy works
A fixed, documented 70/30 blend: 70% weight on interest efficiency (how far above the lowest rate in your debt list a given debt sits) and 30% weight on early-win momentum (how close to your smallest balance it sits). It's computed once from your actual numbers, not an arbitrary label.
How interest is calculated
Each debt accrues interest monthly at its stated APR (or promotional APR, if provided, until it expires), minimums are paid first, and any remaining budget rolls to the priority debt under your chosen strategy — a real amortization simulation, not an estimate.
How extra payments affect payoff
Your results show exactly how much sooner you'd be debt-free and how much interest you'd save at $50, $100, $250, and $500 more per month, plus the impact of any one-time lump sum you plan to apply.
Common payoff mistakes
Chasing the "best" strategy on principle rather than your actual numbers, ignoring promotional APR expiration dates, and committing an entire budget to debt payoff without an emergency reserve are the most common ways a payoff plan goes sideways.
Frequently asked questions
What's the difference between debt snowball and avalanche?
Avalanche pays extra toward your highest-interest-rate debt first, which minimizes total interest paid. Snowball pays extra toward your smallest balance first, which creates faster early wins that can help you stick with the plan.
How does the Miser Optimized strategy work?
It's a documented, fixed 70/30 blend of interest efficiency and early-win momentum — each debt gets a priority score from how far above the group's lowest rate it sits (70% weight) and how close to the group's smallest balance it sits (30% weight). It's not the mathematically lowest-interest option, but often a reasonable middle ground.
What if my budget doesn't cover my minimum payments?
The tool detects this and tells you directly rather than producing a misleading payoff date — you'll need to increase your available budget or address individual debt terms first.
Does this tool tell me to skip payments or take on new debt?
No. It only reallocates extra payment capacity you already have across your existing debts. It never suggests stopping required payments, ignoring an emergency fund, or borrowing more.
