DelDebtThe hybrid debt payoff method is a payoff order that mixes the debt snowball (smallest balance first) with the debt avalanche (highest APR first). The name is used for two different rules. One version ranks debts by debt-to-interest ratio, balance divided by APR, and pays the lowest ratio first. The other, sometimes called the blizzard, pays the smallest debt first for a quick win and then switches to the avalanche. The calculator below runs both, plus snowball and avalanche, on your own debts.
Two things people call "hybrid"
Debt-to-interest ratio
This version divides each balance by its APR (in percent) and puts the lowest result first. Undebt.it, a popular web-based debt planner, offers it under the name Debt Hybrid and describes it as a debt-to-interest ratio. The idea: a debt that is both small and expensive should go first, because it's quick to close and costly to keep.
A $2,500 store card at 27.99% has a ratio of 2,500 ÷ 27.99 = 89. A $7,000 Visa at 24.99% has a ratio of 280. The store card goes first even though the Visa carries more interest in dollars, because the store card is small enough to finish soon and its rate is higher.
The ratio rewards high rates and small balances at the same time. A tiny debt at a low rate can still rank early, and a big debt at a very high rate can rank late. That's the point of the compromise.
Blizzard: smallest first, then avalanche
The second version is simpler. Pay off your single smallest debt first, whatever its rate, to get an early win. After that, ignore balances and go by APR, highest first, like the avalanche. The DelDebt planner calls this method blizzard.
The blizzard only differs from the avalanche at the very start. If your smallest debt is also your highest-rate debt, the blizzard and avalanche are identical.
How the calculator works
Enter up to ten debts with their name, balance, APR and minimum payment, then the extra amount you can pay every month on top of the minimums. The Hybrid button uses the debt-to-interest ratio. The results show:
- your debt-free date, number of months and total interest;
- interest saved compared with paying minimums only;
- the payoff order, with the month each debt reaches zero;
- a comparison table of all four methods on the same numbers: avalanche, snowball, hybrid (ratio) and blizzard;
- a month-by-month table you can download as CSV.
All methods use the same monthly budget. When a debt is paid off, its minimum rolls into the next debt in line. Interest is charged at APR divided by 12 each month, so expect small differences from your statements, since card issuers accrue interest daily.
Worked example: four debts, four orders
Here are four debts where every method picks a different order. The extra payment is $200 a month on top of $465 in minimums, so the total budget is $665.
| Debt | Balance | APR | Minimum | Balance ÷ APR |
|---|---|---|---|---|
| Medical payment plan | $1,200 | 8.99% | $50 | 133 |
| Store card | $2,500 | 27.99% | $75 | 89 |
| Personal loan | $4,000 | 11.99% | $130 | 334 |
| Visa | $7,000 | 24.99% | $210 | 280 |
Each method's order and results:
| Method | Payoff order | First debt closed | Debt-free in | Total interest |
|---|---|---|---|---|
| Avalanche | Store card, Visa, Medical, Personal loan | Month 11 | 28 months | $3,757.57 |
| Hybrid (ratio) | Store card, Medical, Visa, Personal loan | Month 11 | 28 months | $3,844.76 |
| Blizzard | Medical, Store card, Visa, Personal loan | Month 5 | 29 months | $4,040.92 |
| Snowball | Medical, Store card, Personal loan, Visa | Month 5 | 29 months | $4,282.46 |
The ranking in interest is what you'd expect: avalanche cheapest, snowball most expensive, the two hybrids in between. The ratio hybrid costs $87.19 more than the avalanche, and it closes two debts by month 13 instead of one. The blizzard costs $283.35 more than the avalanche but gives you a closed account in month 5, and still saves $241.54 compared with the pure snowball.
For reference, paying the same minimums with no extra (freed-up minimums still rolling forward) would cost about $7,487 in interest. Every method here saves between $3,205 and $3,730 of that.
How the gap moves with the extra payment:
| Extra per month | Avalanche | Hybrid (ratio) | Blizzard | Snowball |
|---|---|---|---|---|
| $100 | $4,977.02 | $5,003.77 | $5,268.23 | $5,405.66 |
| $200 | $3,757.57 | $3,844.76 | $4,040.92 | $4,282.46 |
| $400 | $2,564.68 | $2,677.56 | $2,793.53 | $3,061.41 |
The order of the methods stays the same at every budget. With $400 extra, the snowball costs $496.73 more than the avalanche, while the ratio hybrid costs only $112.88 more.
Which hybrid should you use?
Start with what you need from the plan.
- You want the lowest interest and don't need early wins: use the avalanche. In most real cases, no order costs less.
- You want the avalanche, but a small, high-rate debt is sitting in the middle of the list: the ratio hybrid pulls it forward. It usually costs little extra, and a second closed account arrives sooner.
- You've quit plans before and need a win in the first few months: the blizzard gives you one closed account right away and then stops paying for motivation. It's a good compromise when the snowball's extra cost looks too high.
- All your debts have similar rates: the methods converge, and the snowball costs almost nothing extra. Pick the one you'll stick with.
The details are in which debt to pay off first, and each classic method has its own page: the debt avalanche calculator and the debt snowball calculator. If a consolidation loan is on the table, compare it on the same budget first: debt consolidation vs. avalanche.
Watch out for 0% and very low rates
The ratio divides by the APR, so a debt at 0% has no meaningful ratio. The calculator puts 0% debts last, which is also what the avalanche does. But a 0% promotional rate usually ends. If the promo expires before you'd reach that debt, enter it at the rate that applies after the promo, or make sure it gets enough each month to be paid off before the end date.
Very low rates push the ratio up quickly, so a small loan at 2% can rank behind a much larger card at 25%. That's intended: paying off cheap debt early saves little.
Keep the plan going
Choosing the order is the easy part. Following it for two or three years is harder. The DelDebt planner saves your debts and lets you pick snowball, avalanche, blizzard, cash flow (largest minimum first) or a custom order. You can set a custom order to match the ratio hybrid from this calculator. It logs payments, reminds you of due dates and works without an account.
FAQ
What is the debt-to-interest ratio method?
It's a payoff order where you divide each debt's balance by its APR and pay the debt with the lowest result first. Small debts with high rates rise to the top, which blends the snowball's quick wins with the avalanche's interest savings.
Is the hybrid method better than the avalanche?
Not in total interest: with a fixed budget, the avalanche is almost always cheapest. The hybrid trades a small amount of extra interest for closing some debts sooner, which helps people who need visible progress.
What is the debt blizzard method?
The blizzard pays off your smallest debt first for a quick win, then orders the rest by APR, highest first. It costs more interest than the avalanche but usually less than the snowball.
Is Undebt.it's Debt Hybrid the same as this calculator's hybrid?
Both are described as a debt-to-interest ratio, and this calculator computes it as balance divided by APR, lowest first. Different tools can handle ties, 0% debts and rounding differently, so check the order each one shows before comparing results.
What if two debts have the same ratio?
The calculator puts the one with the higher APR first. In practice, the difference in interest between the two orders is usually tiny.
