Debt Payoff Calculator

This works out how long it takes to clear one or more debts and the cheapest order to attack them, with room for extra payments. It uses the debt avalanche method, which produces the lowest total interest of any repayment order. Add as many debts as you carry, and the schedule underneath shows when each one clears.

Debt in ordinary life

Borrowing is a normal part of a modern economy. Companies, individuals, and governments all run on it. Most people take on some form of it during their lives, whether a mortgage, student loans, a car loan, credit card balances, or something else.

Used sensibly, debt lets people own homes, buy cars, and keep life moving. It can also become a serious source of stress, and prolonged financial strain shows up as genuine mental and physical health problems. Excessive debt, credit card balances in particular, tends to encourage more spending, which costs real money in interest, disrupts any financial plan, lowers credit scores, and eventually spills into life outside money.

Paying debts off early

Most people like the idea of being debt-free and will clear balances early when they can. The usual route is paying more than the required minimum, either as extra each month, an annual lump, or a single one-off payment. All three are available above.

Extra payments reduce the principal directly, which pulls the payoff date forward and cuts the interest paid across the life of the debt. On the default figures, adding $100 a month clears everything 51 months sooner and saves about $22,000 in interest, which is a large return on $100.

Two things to check before committing. First, whether any of the loans carries an early payoff penalty; some do, and it can erase the saving. Second, the opportunity cost. An emergency fund is worth more than an extra payment on a cheap loan when a medical bill or a car repair arrives, and money invested over decades has historically returned more than the interest saved on low-rate debt.

The conventional sequence holds up well. Clear high-interest debt such as credit cards as fast as possible, since almost nothing reliably returns 19% a year. Then decide case by case whether extra payments on a low-rate mortgage beat investing the same money.

Finding the money

Deciding to pay early is easier than doing it, and the gap is usually financial discipline rather than knowledge. The money tends to come from building an actual budget, cutting spending that was not adding much, selling things you no longer use, and adjusting how you live for a while. Our Budget Calculator is the place to start on the first of those.

One structural point worth knowing: a raise or a bonus is the easiest source of extra payments, precisely because you were not spending it before. Directing new income at debt before it becomes part of your normal spending avoids the feeling of sacrifice entirely.

The debt avalanche

This method produces the lowest total interest cost, and it is what the calculator uses. Every debt gets its minimum payment, without exception, and everything left over goes to the debt with the highest rate. When that clears, the money tumbles onto the next highest, and so on until nothing is left, which is where the name comes from.

Rate decides the order, not balance. A credit card at 18% is attacked before a 12% personal loan and long before a 5% mortgage, no matter how large the mortgage is. The results table orders debts by payoff date, with the highest rates clearing first.

The defaults show it working across four debts totalling $284,000. Paying $2,629 a month, of which $100 is extra, clears everything in 136 months, or 11 years and 4 months. The total paid is $356,852.87, of which $72,852.91 is interest. The 18.99% card goes in month 31, the 16.99% card in month 39, the auto loan in month 48, and the mortgage finishes the job.

The fixed total payment setting

This option matters more than it looks, and it is where most of the saving comes from.

Set to Yes, the money freed when a debt clears rolls onto the remaining debts, so your total monthly outlay stays the same until everything is paid. Clearing the $150-a-month credit card does not give you $150 back; it gives the next debt an extra $150 a month. That rolling effect is what makes the avalanche accelerate.

Set to No, the payment simply stops and your monthly outlay falls with each debt cleared. That is more comfortable month to month and considerably more expensive overall, because the remaining debts keep accruing at their own pace. Toggle between the two on your own numbers and the difference is usually stark.

The debt snowball

The alternative orders debts by balance rather than rate, smallest first, regardless of what each one charges. As each small debt disappears, its payment moves to the next smallest.

It costs more in interest, sometimes considerably. Its argument is behavioural rather than mathematical: clearing a whole debt in a few months provides visible progress, and visible progress keeps people going. Research on repayment behaviour has found that people using the small-balance-first approach are more likely to stay with a plan. If you have started a payoff before and abandoned it, the cheaper method is not the better one for you.

Debt consolidation

Consolidation replaces several debts with one larger loan, usually a personal loan, a home equity loan, or a balance-transfer credit card, ideally at a lower rate. It helps most against high-interest balances, can reduce the monthly payment, and collapses several due dates into one, which removes a lot of the administrative failure risk.

Two cautions. Extending the term can lower the monthly payment while raising the total interest, so compare total cost rather than the monthly figure. And moving unsecured card debt onto a home equity loan converts it into debt secured against your house, which changes the consequence of a future problem from a damaged credit file to a threatened home. Our Debt Consolidation Calculator runs the comparison.

When the debt cannot be repaid

Sometimes the numbers simply do not work, whether through lost income, serious illness, or debts that grew past any realistic payment. The United States offers several formal routes, and all of them carry costs. Higher total expense, damaged credit, and in some cases more debt are all possible outcomes, which is why many advisers treat these as last resorts rather than tools.

Debt management. A credit counsellor reviews your position and negotiates with creditors, often for lower rates or payments. The U.S. Department of Justice publishes a list of approved credit counseling agencies by state, and using an approved non-profit agency matters. If a plan is workable, you make one monthly payment to the agency, which pays each creditor, usually alongside a modest fee. Expect to close credit cards and open no new credit while the plan runs. It stops the calls and letters, works best for people disciplined enough to stay the course, and while it dents a credit score initially, it avoids the far heavier damage of settlement or bankruptcy.

Debt settlement. Negotiating to pay less than you owe, typically settling at around half the balance, with fees often near 20% of the outstanding amount. The credit damage is severe, and there is a tax sting people rarely anticipate: the IRS generally treats forgiven debt as taxable income, so a $20,000 reduction can produce a real tax bill. Settlement companies also usually require you to stop paying creditors while they negotiate, which does the credit damage before any deal exists.

Bankruptcy. The legal status of someone who cannot repay. Six types exist; two apply to individuals. Chapter 7 discharges debt and removes the legal obligation to repay, usually at the cost of selling some assets, and it cannot clear tax debt, student loans, child support, or alimony. It typically runs six months to a year. Chapter 13 is a reorganisation onto a payment plan of three to five years, after which the remainder is discharged, and it often lets you keep valuable assets rather than having them sold. Which one applies depends mostly on your income and assets. Either way it stays on a credit report for up to a decade, making loans, mortgages, and new cards hard to obtain, and landlords and some employers view it unfavourably.

Reading the schedule

Look past the payoff date at two figures. The first is total interest as a share of what you pay, which tells you how much of your money is buying nothing. The second is the effect of small changes: raise the extra payment by $50 and watch both the date and the interest move, usually further than the amount suggests.

The assumption that undoes everything is new borrowing. The schedule assumes the balances only fall. Keep charging to the cards and the payoff date recedes faster than payments bring it closer. For cards alone, the Credit Card Payoff Calculator gives a focused view.
