Medical debt payoff calculator

Payoff date for $3,600 at 0%, paying $150.00/monthworked example

August 1, 2028

Time to zero: 2 years
Total interest: $0.00A 0% provider plan adds nothing on top of the balance
Total paid: $3,600.00
Comparison scenario: same numbers at a 22% card APR: 2 yr 8 mo · $1,187.42 interest

Paying $150.00 every month clears this $3,600 balance in 2 years with $0.00 of interest — a 0% provider plan is just the balance divided into payments. As a comparison scenario, the same balance and payment at a 22% card APR would take 2 yr 8 mo and cost $1,187.42 of interest. Before committing to a plan, the negotiate section's itemized-bill and charity-care letters cost a stamp.

Balance ($)The total from the billing office, after insurance.APR (%)Provider payment plans are usually 0%. Enter a rate only if this debt sits on a credit card.Monthly payment ($)The monthly amount on the plan.

Medical debt usually sits on a 0% hospital payment plan — so the math is months, not interest, unless it has moved to a credit card. This calculator handles both cases, shows the difference between them in dollars, and points at the negotiation letters worth sending before you commit to any plan.

How to use this calculator

1
Check the bill before you plan around it
Request an itemized bill and read it: duplicate charges, unbundled line items, and services never received are common enough that template letters for each exist on this site. A plan built on an unchecked bill can be a plan to overpay on schedule.
2
Leave the rate at 0% for a provider plan
Hospital and provider payment plans are commonly interest-free, so the schedule is just balance divided by months. If the debt has moved to a credit card or a medical financing card, enter that card's APR instead — the math changes completely.
3
Look at the card comparison row
The tool shows the same balance at a typical card APR beside your plan. That comparison is the argument for keeping medical debt where it is rather than moving it onto plastic, and it is a real number rather than general advice.
4
Ask about financial assistance before agreeing to terms
Nonprofit hospitals are required by federal rules to have a financial assistance policy, and many discount or forgive bills well above the poverty line. Ask before you sign a payment plan; a plan agreed in month one is harder to revisit in month six.

Frequently asked questions

Why does the interest rate default to zero here?

Because hospital and provider payment plans are commonly interest-free — the balance divided by the months is the whole schedule. The rate field exists for the other case: medical debt that has been put on a credit card or a medical financing card, where ordinary card APRs apply and the payoff math changes completely.

Should I put a medical bill on a credit card?

That is a decision with consequences a calculator cannot weigh — but it can show you the arithmetic: the same balance at 0% on a provider plan versus card APR, side by side. Moving medical debt to a card can also change protections and reporting treatment. Before committing to either, the negotiation letters on this site cost a stamp.

What should I do before agreeing to any payment plan?

Request an itemized bill and check it — duplicate charges and billing errors are common enough that a template letter for each exists on this site. If the provider is a nonprofit hospital, federal 501(r) rules require it to have a financial assistance policy, and the charity-care screener here shows how eligibility bands typically work.

Does medical debt affect credit like card debt?

Reporting treatment for medical collections has changed several times in recent years and depends on amount, age, and the bureaus' current policies — this calculator does not model credit reporting at all. What it models is the payment schedule; for reporting questions, the CFPB's medical-debt pages are the source of record.

How exact is the card-comparison row?

It applies this site's standard convention — interest accruing monthly at APR divided by 12 — to the same balance at a representative 22% card rate, purely to show the shape of the difference. Your actual card APR is what to enter in the rate field; issuers also compound daily, which makes real card totals slightly higher still.
