One per line: name (optional), balance, rate (% per year), monthly payment. Leave out thousands separators.
When a debt is repaid, its payment moves to the highest-rate debt left, so your total monthly payment stays the same. Turn off if each payment stops when its debt is repaid.

Cách tính S
  1. Current debts

    interest=24,896.16−16,900=7,996.16\text{interest} = 24{,}896.16 - 16{,}900 = 7{,}996.16

    All payments minus the balances. 3 debts totaling $16,900.00, paid at $560.00 a month (cleared debts' payments move to the highest-rate debt left): repaid after 45 months.

  2. Loan amount and fee

    L=16,9001−0.05=17,789.47,fee=889.47L = \frac{16{,}900}{1 - 0.05} = 17{,}789.47,\quad \text{fee} = 889.47

    The lender keeps the fee out of the loan, so you borrow more than the debts to receive enough to clear them.

  3. Loan payment

    M=L r (1+r)48(1+r)48−1=468.38M = \frac{L\,r\,(1+r)^{48}}{(1+r)^{48}-1} = 468.38

    r = 11.99 ÷ 1,200 = 0.00999167 a month.

  4. Total saved

    24,896.16−48×468.38=2,414.0324{,}896.16 - 48 \times 468.38 = 2{,}414.03

    Current total of payments against the loan's payments plus any cash added at closing.

  5. Loan APR including the fee

    16,900=M×1−(1+i)−48i ⇒ APR=12i=14.77%16{,}900 = M \times \frac{1 - (1+i)^{-48}}{i}\ \Rightarrow\ \text{APR} = 12i = 14.77\%

    The fee is a prepaid finance charge, so the APR treats the loan as the amount after the fee (Regulation Z). Solved by bisection.

  6. Break-even loan rate

    At 17.58% with the same term and fee, the loan costs exactly what the current debts do; any lower rate saves money.

Giới thiệu Debt consolidation calculator

Two plans are run month by month. Now: each debt accrues its APR ÷ 12 and takes its own payment, and when a debt is cleared its payment moves to the highest-rate debt left. Consolidated: one loan repaid by M = L × r × (1 + r)^n ÷ ((1 + r)^n − 1). When the origination fee comes out of the loan, you borrow the debts ÷ (1 − fee) to receive enough to clear them. The saving is the total paid now minus the loan's payments and any cash added.

With the defaults, three debts totaling 16,900 at 560 a month take 45 months and 7,996.16 of interest. A 48-month loan at 11.99% with a 5% fee borrows 17,789.47, costs 468.38 a month and saves 2,414.03. Its APR with the fee is 14.77% against a combined 22.09% on the debts, and it saves money at any rate below 17.58%.

Rates are held fixed, and cleared cards are assumed to carry no new balances. Promotional balance-transfer rates are not modeled.

Câu hỏi

Is debt consolidation worth it?

Only if the loan's interest and fees come to less than the interest you would pay on the debts at your current payments. The three default debts, 16,900 in all, cost 7,996.16 of interest over 45 months. A 48-month loan at 11.99% with a 5% fee costs 4,692.66 of interest plus 889.47 of fee, saving 2,414.03 and lowering the payment by 91.62 a month.

Does a longer consolidation loan save more money?

No. A longer term lowers the payment but adds interest. For the default debts at 11.99% with a 5% fee, 36 months costs 590.78 a month and saves 3,628.08; 48 months costs 468.38 and saves 2,414.03; 60 months costs 395.63 and saves 1,158.53; 72 months costs 347.70 and loses 137.89. The CFPB warns that paying over a longer time could mean paying a lot more overall.

How does an origination fee change the cost of a consolidation loan?

It raises the amount you borrow and the APR. To receive 16,900 when a 5% fee is taken from the loan, you borrow 16,900 ÷ 0.95 = 17,789.47, and the APR rises from 11.99% to 14.77% because the fee counts as a prepaid finance charge. With no fee the default loan saves 3,538.14; with 5% it saves 2,414.03; with 8% it saves 1,680.92.

What is the break-even interest rate for debt consolidation?

The loan rate at which consolidating costs exactly what keeping the debts would. Below it you save; above it you lose. For the default debts with a 5% fee, the break-even rate is 23.32% for a 36-month loan, 17.58% for 48 months, 14.11% for 60 months and 11.78% for 72 months, which is why the 72-month loan at 11.99% costs more.

Why is my combined APR different from the average of my rates?

The combined APR is the single rate that turns your actual payment stream into the total you owe, so it weights each debt by how long its balance stays unpaid. The default debts carry 23.99%, 29.99% and 14.5%, a balance-weighted average of 21.47%; paid at 560 a month with payments moving to the highest rate, they behave like one loan at 22.09%. Compare that figure with the loan's APR including fees.
