Multiple Debt Payoff Calculator

How it works

With several debts, the fastest route is not to split your money evenly. You pay the minimum on each to keep them current, then pile every spare dollar onto one target debt until it is gone, and roll its whole payment onto the next. Your total monthly outlay stays flat while the amount hitting the target debt keeps growing.

By default this calculator targets the highest rate first, the avalanche order, for the lowest total interest:

With the defaults, three debts totalling $17,000 with $200 extra a month clear in about 43 months for roughly $2,943 in interest, paying the highest-rate debt first. The total you pay each month, the minimums plus the extra, never changes; what changes is how much of it lands on the debt you are currently attacking.

A worked example: three cards and an extra $200 a month

Three balances, one budget: a $2,000 card at 26%, a $6,000 loan at 12%, and $9,000 at 8%. That is $17,000 of debt total, and you can put an extra $200 a month toward it beyond the minimums.

Rolled together, your payments add up to $540 a month. The plan hits the 26% card first, since the highest rate costs you the most, then rolls that freed-up money onto the $6,000, then the $9,000. Working the list in that order, you are debt-free in 43 months, which lands in February 2030.

Over those 43 months you pay about $2,943 in interest, far less than letting the high-rate card linger. Enter your own balances, rates, and extra payment to see your payoff order and date.

Running the plan

• Keep the total payment fixed. As each debt clears, do not lower what you pay overall. Redirecting the freed-up money is what makes the later debts fall quickly.
• Automate the minimums. Missing one brings fees and rate jumps. Set every minimum on autopay, then send your extra manually to the target debt.
• Prefer the highest rate, unless you need a win. Highest-rate-first is cheapest, but if a small balance is dragging on your motivation, clearing it first can be worth a little extra interest.

Why concentration beats spreading

Faced with several debts, the instinct is to spread any extra money evenly across all of them. That feels fair, but it is the slow way out. Splitting the extra means every balance inches down together and none of them actually closes, so you keep paying every minimum for longer.

Concentration works better: pile the whole extra on one target while paying minimums on the rest, and that debt clears far sooner.

• Closing a debt frees its payment. Once a balance hits zero, its minimum is yours to redeploy, which spreading never lets you do because nothing ever finishes.
• The attack money keeps growing. Each freed minimum rolls onto the next target, so the amount hitting it climbs while your total outlay stays flat.
• Fewer open balances lowers risk. Every account you close is one less minimum to miss and one less rate that can rise on you.

The order you attack in, highest rate or smallest balance, is a smaller decision than the choice to concentrate at all. Whichever target you pick, focusing your extra on one debt at a time and rolling each freed payment forward is what clears the whole group years faster than dividing the same money evenly across everything.

Reading a single debt-free date

The payoff of entering everything together is one date instead of several. Rather than tracking each balance separately and guessing when the last one lands, you get a single finish line for the whole group, plus the order the plan clears them in. That combined view is easier to plan around and easier to stay committed to.

• The date assumes you hold the plan. It depends on keeping the total monthly outlay fixed and rolling every freed payment forward. Ease off and the real date slips later.
• The payoff order is your roadmap. It tells you which debt to throw the extra at right now, so you always know where this month’s focus money should go.
• The interest total is the price of the timeline. Shorten it by raising the extra, and watch both the date and the interest improve together.

If the combined date is further out than you would like, the two levers are the same as ever: increase the extra, or reduce the balances with any windfall. If even the minimums barely dent the total, that is a signal to look at consolidation, where a single lower-rate loan might do what stretched payments alone cannot. Either way, the value of the single date is that it turns a messy pile of separate bills into one clear target with one clear finish line.

Point every spare dollar at the current lead debt, hold the total payment steady as each one clears, and the whole group falls in the order the plan lays out. Progress you can see on one timeline is progress you are far more likely to keep.
