How is this calculated?

This calculator uses standard financial formulas to project your payoff timeline, interest costs, and optimal payment strategies based on your current balances, rates, and payment amounts.

Should I pay off debt or save?

Generally, pay off high-interest debt (above 7-8%) first, while maintaining a small emergency fund. Once high-interest debt is gone, balance between building savings and paying off remaining debt.

What is the debt avalanche vs snowball method?

Avalanche targets highest-interest debt first (saves more money). Snowball targets smallest balances first (builds momentum). Both work — choose the one you will stick with.

Things to Know

Essential concepts for understanding your results

Interest Impact

How does interest affect your debt payoff?

Interest is the invisible cost multiplier on debt. On $10,000 at 22% APR with minimum payments: you pay approximately $13,000 in interest — more than the original balance. Every dollar of extra payment goes directly to principal, reducing the balance that generates future interest. Even $50/month extra dramatically shortens the timeline and reduces total cost. The earlier in the loan you make extra payments, the greater the lifetime interest savings.

Strategy Selection

How do you choose the right payoff strategy?

Two proven methods: Avalanche (target highest interest rate first) saves the most money — best when rate differences exceed 5%. Snowball (target smallest balance first) provides fastest motivational wins — best when you need psychological momentum. A hybrid approach (snowball 1-2 small debts for quick wins, then switch to avalanche) captures benefits of both. Either is dramatically better than minimum payments.

Financial Freedom

What should you do after paying off debt?

Redirect 100% of former debt payments to wealth building: emergency fund (3-6 months expenses), then employer 401(k) match, then Roth IRA ($7,000/year), then max 401(k). The discipline that eliminated debt now builds wealth exponentially. A family freeing up $1,200/month from debt and investing it at 8% accumulates $445,000 in 15 years. Debt freedom is not the finish line — it is the launchpad.

How Your Payoff Date Is Calculated

The payoff formula: Months = -log(1 - (Balance × Rate / Payment)) ÷ log(1 + Rate)

Where Rate = monthly interest rate (APR ÷ 12).

Example: $12,000 credit card at 22% APR, $300/month payment.

Monthly rate: 22% ÷ 12 = 1.833%. Months = -log(1 - (12,000 × 0.01833 / 300)) ÷ log(1.01833) = 58 months (4 years, 10 months). Total interest: $5,337. Total paid: $17,337.

Increase to $500/month: 29 months (2 years, 5 months). Interest: $2,349. Savings: $2,988 and 29 months.

The relationship between payment size and payoff time is nonlinear: doubling the payment from $300 to $600 does not halve the time from 58 to 29 months — it cuts it to 23 months (60% reduction) because more of each dollar attacks principal when less goes to interest.

The Power of Extra Payments

Debt: $12,000 at 22%	Payment	Payoff Time	Total Interest	Savings vs Minimum
Minimum only (~$240)	$240	8 yrs, 3 mo	$11,550	—
$300/month	$300	4 yrs, 10 mo	$5,337	$6,213 + 3.4 yrs
$500/month	$500	2 yrs, 5 mo	$2,349	$9,201 + 5.8 yrs
$750/month	$750	1 yr, 6 mo	$1,380	$10,170 + 6.7 yrs
$1,000/month	$1,000	1 yr, 1 mo	$985	$10,565 + 7.1 yrs

Every extra $100/month saves approximately $2,000-$3,000 in interest and 1-2 years. The first $100 above minimum has the biggest impact because it attacks the interest-heavy early payments. Use our Snowball vs Avalanche Calculator to optimize the order of attack across multiple debts.

Frequently Asked Questions

When will I be debt-free?

Depends on your balance, rate, and payment amount. Enter your exact numbers above for a precise date. As a rough guide: paying $300/month on $12,000 at 22% takes 4 years, 10 months. Doubling to $600: 1 year, 11 months. The biggest factor is how much above the minimum you can pay — even $50 extra makes a meaningful difference.

How much faster will extra payments pay off my debt?

On $10,000 at 20%: $50/month extra cuts payoff by 2.5 years. $100 extra: 4 years faster. $200 extra: 5.5 years. Each extra dollar goes directly to principal, which reduces the interest calculated next month, creating an accelerating payoff effect. The earlier you increase payments, the greater the compounding savings.

Should I pay off high-interest debt or save?

Pay off debt above 10% interest first — the guaranteed "return" exceeds what savings or investments reliably produce. Keep a minimal emergency fund ($1,000-$2,000) while aggressively attacking high-interest debt. Once credit card debt is cleared, build the full emergency fund (3-6 months), then balance lower-rate debt payoff with investing. See our Investment Calculator for comparison.

What is the minimum payment trap?

Credit card minimums (1-3% of balance) are designed to maximize interest revenue, not help you pay off debt. On $12,000 at 22% with minimum payments: 8+ years to pay off, $11,550 in interest — nearly doubling the original balance. The minimum is the bank's preferred payment, not yours. Always pay the maximum you can afford. See our Minimum Payment Calculator for the full impact.

Does paying off debt improve my credit score?

Yes — significantly and quickly. Reducing credit utilization (balance ÷ limit) from 50% to under 10% can boost your score by 40-80 points within 1-2 months. Paying off an installment loan (car, student) has a smaller but still positive effect. The credit score improvement from debt payoff often enables better rates on future borrowing — a compounding benefit. See our Credit Utilization Calculator.
