Debt Settlement Calculator: What Would You Actually Pay?

$7,500 × 40% = $3,000. That's what a debt settlement calculator shows for a hypothetical $7,500 credit card settled at 40%: $3,000 to the creditor and $4,500 forgiven. It's the right first line of the math and the wrong last one. Tax on the forgiven $4,500 is $540 at a 12% federal rate if nothing is excluded, and a settlement company charging 25% of the amount saved would take $1,125, so $1,665 sits under that $3,000 before the balance gains any interest or late fees.

A debt settlement calculator is a tool that estimates what settling a debt for less than you owe will cost: it multiplies the balance by a settlement percentage to get the payment, then subtracts the payment from the balance to get the amount forgiven. The worked examples below are hypothetical arithmetic on that one balance, not a forecast of what any creditor accepts.

Hypothetical. 25% is the FTC's worked-example fee, not a market rate; insolvency can reduce or erase the tax.

How does a debt settlement calculator work?

A debt settlement calculator turns a balance and a settlement percentage into the payment and the forgiven amount, and a complete one also takes your tax rate, any fee, your monthly savings and the card's interest rate. A settlement costs the payment, plus any tax on the forgiven amount, plus any fee, plus whatever the balance grows by before you pay.

Take the balance from your latest statement or a collector's validation notice. How debt settlement works covers the process around these numbers.

Part of the cost	Formula	Hypothetical $7,500 card at 40%
Settlement payment	Balance × settlement percentage	$7,500 × 40% = $3,000
Forgiven amount	Balance − payment	$7,500 − $3,000 = $4,500
Tax, if nothing is excluded	Forgiven amount × marginal tax rate, roughly	$4,500 × 12% = $540
Company fee, percentage of savings	Fee percentage × (enrolled balance − amount paid)	25% × $4,500 = $1,125
Months to save	Settlement amount ÷ monthly savings	$3,000 ÷ $250 = 12 months
Monthly interest before charge-off	Balance × APR ÷ 12	$7,500 × 22.36% ÷ 12 = $139.75

How much will you pay to settle your debt?

To settle a debt, you'll pay the balance times the settlement percentage you and the creditor agree on, so a hypothetical $7,500 balance settled at 40% costs $3,000 and leaves $4,500 forgiven.

Read the last column first. On this balance, each 10 points off the settlement cuts the payment by $750 but adds $90 of tax at 12%, so it's worth $660 to you. And pay nothing until a signed letter says your amount settles the debt in full; what a debt settlement agreement should say lists the terms.

What settlement percentage should you use in a debt settlement calculator?

Use two or three hypothetical percentages in a debt settlement calculator, not one, because no published average applies to your account: what a creditor accepts depends on who owns the debt, how far behind it is, whether you can pay a lump sum, and the owner's own policy.

The Consumer Financial Protection Bureau's settlement guidance, last reviewed October 15, 2026, has you confirm that you owe the debt, then work out the total you're willing to pay, and warns: "Don't pay more than you can afford." It adds that you "may have more room to negotiate with a debt collector than you did with the original creditor." Set your ceiling at what you could pay without borrowing, then see where to open below it and how to negotiate from there.

How much tax will you owe on a settled debt?

The tax on a settled debt is roughly the forgiven amount times your marginal rate, plus any state income tax, unless an exclusion such as insolvency or bankruptcy applies. At 12%, the hypothetical $4,500 forgiven adds $540 of federal tax; at 22%, it adds $990.

Both are 2026 federal rates: the IRS's tax year 2026 inflation adjustments, released October 9, 2025, put a single filer at 12% on taxable income over $12,400 and 22% over $50,400 ($24,800 and $100,800 for married couples filing jointly). A large forgiven amount can spill into the next bracket.

IRS Publication 4681 says: "Even if you didn't receive a Form 1099-C, you must report canceled debt as gross income on your tax return unless one of the exceptions or exclusions described later applies." A lender required to report must file it when it cancels $600 or more, the same publication says.

Check insolvency first. Publication 4681 says you were insolvent "to the extent that the total of all of your liabilities was more than the FMV of all of your assets immediately before the cancellation," FMV being fair market value. You claim the exclusion on Form 982 (line 1b), excluding the smaller of the canceled debt and that gap. In the IRS's own example, $10,000 of liabilities against $7,000 of assets made $3,000 of a $5,000 canceled credit card debt excludable, leaving $2,000 taxable. As a formula: taxable amount = forgiven amount − the smaller of the forgiven amount and your insolvency.

How much do debt settlement companies charge?

A debt settlement company that sells by phone can charge only after it settles a debt and you've paid on it, and only as a proportional share of its total fee or a fixed percentage of the amount it saved you. No federal regulator publishes a current average fee, so get the percentage in writing.

Those limits come from the Federal Trade Commission's Telemarketing Sales Rule. Its advance-fee ban, 16 CFR 310.4(a)(5), forbids any fee until a debt is settled under an agreement you signed and you've made at least one payment under it. The percentage can't change from debt to debt, and the amount saved is "the difference between the amount owed at the time the debt was enrolled in the service and the amount actually paid to satisfy the debt." It covers phone sales, including calls you make after seeing an ad, but not a sale completed only after a face-to-face presentation (16 CFR 310.6(b)(3) and (b)(5)).

The FTC's compliance guide to the rule (July 2010) works both shapes through. In its Example 13, a company charging 25% of savings settles a $1,000 debt for $600 and "may collect a fee of $100 – 25% of the $400 Barbara saved." In Example 12, a $600 total fee on three $1,000 debts allows a $200 fee once one of them is settled. As formulas:

• Percentage-of-savings fee = fee percentage × (balance at enrollment − amount paid)
• Proportional fee = total fee × (this debt's enrolled balance ÷ all enrolled debt)

If you save in a dedicated account, the FTC notes its independent administrator "may charge the customer a reasonable fee."

Whether debt settlement is legal covers state rules and scams; settlement companies against doing it yourself weighs what the fee buys.

Is it cheaper to settle debt yourself, use a company, or use a platform?

For the same settlement, settling debt yourself is the cheapest route in dollars, since it adds nothing to the payment and the tax. A settlement company adds a fee tied to the debt you enroll or to what it saves you, and a subscription platform adds a monthly price that doesn't move with the balance. On the hypothetical card, with $540 of tax on every route, the totals are $3,540 yourself, $3,888 on a 12-month subscription and $4,665 with a company charging 25% of savings.

The subscription line uses Felix's list price as an illustration: $29 a month for a base plan covering up to three enrolled accounts at a time and $5 a month for each account after that, or $249 a year plus $50 a year per additional account, as shown in Felix's pricing. Prices can differ through partners, and 12 months is an assumption, not a forecast.

Hypothetical: 40% settlement and 12% tax on every route; bars scaled to the $7,500 balance. Growth while saving not included.

More accounts shift the comparison. Three of these hypothetical cards fit in the $29 base and five would cost $29 + 2 × $5 = $39 a month, while a 25%-of-savings fee on three cards settled at 40% would total $3,375. A year with nothing settled shifts it back, since a contingent fee is then owed on nothing while the monthly plan still bills $348. For one small account, do it yourself.

How long does it take to save for a debt settlement?

The months it takes to save for a debt settlement are the settlement amount divided by what you can set aside each month, rounded up: $3,000 at $250 a month is 12 months, and at $400 a month it's 8, since 7.5 rounds up. Reserving the tax as well makes it $3,540 ÷ $250 = 14.2, so 15 months.

That assumes a lump sum and a target that holds still, which on a delinquent card it usually doesn't. The CFPB says a settlement "could be one payment or a series of smaller payments," so a payment plan may let you start sooner, and how long debt settlement takes adds the negotiating time.

Does the balance keep growing while you save?

A credit card balance you've stopped paying keeps growing while you save, from interest and a late fee for each missed payment, until the issuer charges the account off, which federal bank regulators' policy sets at 180 days past due for open-end credit such as cards. After charge-off, whether it keeps growing depends on who owns the debt, your contract and your state's law.

Monthly interest is roughly balance × APR ÷ 12. The Federal Reserve's G.19 consumer credit release put the average rate at commercial banks on credit card accounts assessed interest at 22.36% in August 2026, a preliminary figure published October 7, 2026. At that rate the hypothetical $7,500 balance gains $139.75 a month before compounding.

The CFPB's 2024 rule that would have cut the late-fee safe harbor to $8 for large issuers was stayed before it took effect and vacated by court order on April 15, 2025. That most likely leaves the earlier safe harbor in place, though no CFPB document since has restated it: up to $30 for a late payment and $41 for another within the next six billing cycles, without the issuer justifying the fee by its costs, as the Bureau's March 2024 rule describes. Your cardholder agreement shows your card's fee. Past 60 days late, an issuer can also raise the rate on the existing balance after written notice (12 CFR 1026.55(b)(4)).

Over six months to charge-off, interest of $838.50 plus $235 of late fees at those amounts ($30 + 5 × $41) takes $7,500 to $8,573.50 before compounding, so a 40% settlement becomes $3,429.40, and at $250 a month you need 14 months rather than 12. In the FTC's Example 8, a $10,000 card gained $2,000 of interest and late fees in the year before it settled. The 180-day rule is in the federal banking agencies' retail credit policy (June 2000), and what happens when you stop paying a credit card walks through each month.

What can't a debt settlement calculator tell you?

A debt settlement calculator can't tell you whether a creditor will agree to settle, what settling will do to your credit, or whether you'll be sued while you save, because those turn on the account's owner, your credit file and the debt's age.

• Whether anyone says yes. No creditor has to settle, and the CFPB warns, "Certain creditors may also refuse to work with the debt settlement company you choose." Here's what to do when a creditor refuses to settle.
• The credit cost. The missed payments before a settlement can be reported, and a charged-off or collection account can stay on your credit reports for up to seven years, counted from 180 days after the delinquency began (15 U.S.C. § 1681c). Settling doesn't restart that clock. Settlement's effect on your credit explains why nobody can quote the point drop in advance.
• A lawsuit. If court papers arrive while you save, talk to a lawyer or legal aid office before negotiating further; being sued by a debt collector covers the deadlines.
• An old debt's clock. In some states a payment, or even a promise to pay, can restart the time a creditor has to sue, so check what restarts the statute of limitations before you send money.

If no percentage fits your budget, the other ways to handle debt you can't repay may suit you better, and whether debt settlement is worth it comes before any of this math.

Where Felix fits

Felix is a debt negotiation platform: software that drafts settlement letters for the unsecured accounts you choose to enroll, such as credit cards, store cards, personal loans, medical bills, private student loans and accounts already with a collector. You read and e-sign each letter, it's mailed in your name from your own return address, and you upload what comes back. Offers are laid out in plain numbers so you can run this arithmetic before deciding, and Felix never holds your money: if you accept, you pay the creditor directly.

The subscription's base covers up to three enrolled accounts at a time, with a smaller amount for each one after that, never a percentage of your debt or savings. A soft credit pull that doesn't affect your score finds the accounts (privacy policy). No creditor has to settle, and Felix can't promise a result or a timeline or remove accurate information from a credit report. If court papers arrive on an account, Felix pauses the letters on it and points you to a lawyer or legal aid. Secured, federal student loan and government debts are out of scope; the FAQ covers the rest.
