What is a debt-to-income ratio?

Your DTI ratio is your total monthly debt payments divided by your gross monthly income. Under 20% is excellent, 20-35% is manageable, 36-50% is concerning, and above 50% means debt is consuming most of your income.

Q: What is the debt avalanche method?

The debt avalanche method directs extra payments toward the highest interest rate debt first. It is mathematically optimal and always saves more money in total interest than the snowball method when debts have different rates.

Q: Which method saves more money?

The avalanche method always saves more money in total interest paid. Use the Compare Both option to see the exact dollar difference for your specific debts.

Q: What is the rollover effect?

When a debt is fully paid off, instead of spending that freed payment, you immediately redirect it to the next priority debt. This creates an ever-growing payment directed at fewer remaining debts — dramatically accelerating your debt-free timeline.

Q: Should I pay off debt or build savings first?

Build a $1,000 starter emergency fund first, then capture any employer retirement match, then aggressively pay high-interest debt above 7-8%.

Q: When should I speak with a credit counsellor?

Consider non-profit credit counselling if your total minimum payments exceed 20% of take-home pay, you are missing payments, using credit cards for groceries, or feel genuinely overwhelmed. Credit Counselling Canada and the NFCC (US) offer free guidance.

How the Debt Payoff Calculator Works

DebtCrusher calculates exactly when each of your debts will be paid off under your chosen strategy, how much total interest you will pay, and how that compares to paying only minimums. It uses the correct rollover method — when a debt is fully paid off, its freed minimum payment immediately stacks onto the next priority debt, dramatically accelerating your payoff timeline.

Choose Your Strategy

Select Snowball (smallest balance first), Avalanche (highest interest first), or Compare Both to see the exact difference in time and money for your specific debts.

Enter Your Debts

Add each debt with its name, current balance, annual interest rate and minimum monthly payment. Add as many as you have — credit cards, car loans, lines of credit, student loans.

See Your Full Plan

See your debt-free date, total interest cost, minimum-only comparison, DTI ratio, and lump sum impact. Use the extra monthly payment field to find your fastest possible payoff path.

The Rollover Effect — Why These Methods Work

The single most important concept in strategic debt payoff is the rollover effect. When you fully pay off a debt, instead of absorbing that freed payment into your general spending, you immediately redirect the entire amount to your next priority debt — on top of that debt's existing minimum payment. Each time a debt is eliminated, the total payment directed at remaining debts grows larger. The result is an accelerating payoff where each successive debt falls faster than the one before it.

Food Delivery

$200–$800/mo

DoorDash, Uber Eats, Skip The Dishes. Lunchtime and dinner rush are most profitable.

📦

Sell Surplus Items

Six Strategies to Pay Off Debt Faster

🎯

List Every Debt in One Place

The first step is complete awareness. List every debt — credit cards, car loans, lines of credit, student loans, buy-now-pay-later balances, family loans — with exact balance, interest rate and minimum payment. You cannot create an effective payoff plan without knowing your starting point.

⚙️

Automate All Minimum Payments

Set up automatic payments for the minimum on every debt immediately. Missing a payment triggers late fees, penalty interest rates and credit score damage. Automating minimums lets you focus all energy on the priority debt extra payment rather than juggling due dates manually.

💰

Apply Every Windfall to Debt

Tax refunds, work bonuses, overtime pay, gifts, inheritance and any side hustle income should go 100% to your priority debt. Use the Lump Sum Impact Calculator above to see the exact benefit of any windfall for your specific debts.

✂️

Cut One Expense and Redirect It

Find one non-essential monthly expense to eliminate temporarily — a streaming subscription, gym membership, takeout habit. Redirect that exact dollar amount to your priority debt every month. Even $40-$80 per month adds up to $480-$960 per year applied to debt principal.

🔄

Consider a Balance Transfer

A 0% promotional balance transfer can be powerful for high-rate credit card debt. Moving a balance to a card offering 0% for 12-21 months means 100% of your payment reduces principal. Key: a 3-5% transfer fee applies, and you must clear the balance before the promotion ends.

📈

Increase Income Temporarily

Even a short 6-12 month sprint of higher income directed at debt can change your financial trajectory permanently. See the side hustle ideas above for realistic options. Treat it as a temporary sacrifice with a specific end date tied to paying off your most expensive debt.

Debt Payoff Reference — Extra Payments Make a Big Difference

Here is the real impact of adding extra monthly payments to common credit card debt balances at a standard 19.99% interest rate.

Balance	Rate	Min Only	+$100/mo	+$300/mo	Interest Saved
$2,000	19.99%	~11 years	~20 months	~8 months	~$1,900
$5,000	19.99%	~30 years	~58 months	~20 months	~$5,200
$10,000	19.99%	Never*	~116 months	~38 months	Significant
$15,000	7.99%	~10 years	~89 months	~36 months	~$2,800

*At 19.99%, a 2% minimum payment on $10,000 barely covers interest. Use the calculator above for your exact numbers.

Frequently Asked Questions — Debt Payoff

What is the debt snowball method?

The debt snowball method involves paying minimum payments on all debts while directing all extra money toward the smallest balance first, regardless of interest rate. Once the smallest debt is paid off, its freed minimum payment rolls into the next smallest debt. The snowball method delivers quick psychological wins early in the process, which research shows helps people stay motivated and complete their debt payoff plan.

What is the debt avalanche method?

The debt avalanche method directs all extra payments toward the highest interest rate debt first, regardless of balance. Once the highest-rate debt is eliminated, that payment rolls to the next highest rate. The avalanche method minimizes total interest paid over the life of your debts and is mathematically the optimal strategy. The trade-off is that the first payoff may take longer to achieve, requiring more discipline to stay motivated.

Which method saves more money — Snowball or Avalanche?

The avalanche method always saves more total interest when your debts have different interest rates. The dollar difference depends on how far apart your rates are and how large your balances are. Use the Compare Both feature above to see the exact difference for your specific debts.

What is the rollover effect?

When you fully pay off a debt, instead of spending the freed minimum payment, you immediately redirect it to your next priority debt on top of that debt's existing minimum payment. This creates an ever-growing payment directed at fewer remaining debts — dramatically shortening your total debt-free timeline.

What is a debt-to-income (DTI) ratio?

Your DTI ratio is your total monthly debt payments divided by your gross monthly income, expressed as a percentage. Under 20% is excellent. 20-35% is manageable. 36-50% is concerning. Above 50% means debt is consuming most of your income and should be addressed urgently. Use the DTI calculator in the results panel above to check your ratio.

How can a side hustle help pay off debt faster?

Even a modest side hustle earning $300-500 per month directed entirely at your priority debt can shave years off your timeline. Common options include rideshare driving, food delivery, freelance work, selling unused household items, pet sitting and tutoring. The critical rule: commit 100% of side income to debt payoff — not lifestyle spending.

Should I pay off debt or build savings first?

Build a $1,000 starter emergency fund first so unexpected costs don't force you deeper into debt. Then capture any employer RRSP or 401(k) matching — that is an immediate 50-100% guaranteed return. Then aggressively pay down high-interest debt above 7-8%. High-rate credit card debt costs more than any guaranteed investment can return, making payoff the mathematical priority.

When should I speak with a credit counsellor?

Consider non-profit credit counselling if your minimum payments exceed 20% of take-home pay, you are missing payments, using credit cards for basic living expenses, or feeling genuinely overwhelmed. Credit Counselling Canada member agencies and NFCC member agencies in the US offer free or low-cost guidance and can negotiate with creditors on your behalf.
