Paying off $300,000 in dental debt: three real timelines

$300,000 isn’t an unusual number. The ADEA’s survey of the class of 2025 found 82% of seniors borrowed, and the average among borrowers was $297,800.

At the 2026–27 graduate rate of 8.07% (FSA), $300,000 builds about $2,018 of interest a month. Every month you don’t pay at least that, the loan grows or someone else waives the difference.

Here are three dentists with the same $300,000, three different timelines, and what each one gives up. Every figure comes from the site’s loan math. The refinance numbers are worked examples, not offers: your rate depends on credit and income, and live rates are in the dated table below.

The three timelines at a glance

	Dentist A: 5-year sprint	Dentist B: 10-year steady	Dentist C: PSLF at an FQHC
Job	Private-practice associate, $200,000	Private-practice associate, $160,000	FQHC dentist, $150,000
Loans	Refinanced, 5.0% fixed APR, 5 years (example)	Refinanced, 6.0% fixed APR, 10 years (example)	Federal, on RAP
Monthly payment	About $5,660	About $3,330	About $1,250 to start
Total paid	About $340,000	About $400,000	About $172,000
Left over	$0	$0	About $294,000 forgiven, tax-free
Gives up	Federal protections, and cash flow for 5 years	Federal protections	Job choice: 10 years at a qualifying employer

Dentist C’s total assumes 3% raises a year. Dentists A and B pay a fixed amount no matter what happens to their income.

Dentist A: the 5-year sprint

Dentist A is an associate earning $200,000 at a private practice, with no plans to work for a nonprofit or the government. She refinances to a 5-year loan.

Example: $300,000 at 5.0% fixed APR over 5 years is about $5,661 a month and $339,682 in total. Not an offer; your rate depends on credit.

For comparison, paying the same federal loans off in 5 years at 8.07% takes about $6,093 a month and $365,578 in total. The refinance saves about $26,000, all of it from the lower rate.

The catch is the payment. About $67,900 a year is 34% of her gross pay, before taxes, retirement, rent and a car. One slow quarter, a disability or a baby, and that payment doesn’t move.

This timeline usually works when:

• You already have three to six months of expenses saved.
• You can still put something into retirement.
• You’re not buying a practice in the next year or two, when you’ll want cash on hand.

If any of those fail, a longer term with extra payments gets you most of the savings with less risk. SoFi and Splash both say they charge no prepayment penalty, so you can pay a 10-year loan like a 7-year one and drop back when you need to.

Dentist B: the 10-year steady plan

Dentist B earns $160,000 as an associate and wants a payment that leaves room for retirement savings and, eventually, a practice.

Example: $300,000 at 6.0% fixed APR over 10 years is about $3,331 a month and $399,674 in total. Not an offer; your rate depends on credit.

Keeping the federal loans and paying them off over the same 10 years at 8.07% is about $3,651 a month and $438,112 in total. The refinance saves about $38,400.

Dentist B pays about $60,000 more in interest than Dentist A. In exchange, the payment is about $2,330 a month lower. For most associates in their first five years, that cash does real work: an emergency fund, a Roth IRA, a practice down payment.

Dentist C: PSLF at a community health center

Dentist C works full time at an FQHC, a 501(c)(3) nonprofit, and keeps her loans federal. On RAP, her payment is 10% of her total AGI (the rate for any AGI above $100,000), divided by 12: $150,000 × 10% ÷ 12 = $1,250 a month to start.

That payment doesn’t cover the interest. RAP waives the unpaid interest each month, and the government adds up to $50 a month toward principal, so the balance doesn’t grow (CRS).

After 120 qualifying payments, PSLF forgives what’s left, tax-free (Federal Student Aid). With 3% raises, she pays about $172,000 over 10 years, and about $294,000 is forgiven.

The trade-offs are real. She has to work full time for a qualifying employer for all 10 years, so compare the salary with private-practice offers. A 2025 rule on which employers qualify was vacated by courts on June 30, 2026; the Education Department appealed on Aug. 27, 2026. Check your employer’s status each year.

Refinancing would end all of this. Refinancing turns federal loans into private ones. For those loans you lose RAP, PSLF, federal forgiveness, and federal forbearance and deferment, permanently. The CFPB warns you may also lose federal death and disability discharge.

The slow paths that cost the most

Two federal options look easy and cost the most at associate income:

• Tiered Standard (for new loans from July 1, 2026): $300,000 gets a 25-year term. That’s about $2,329 a month and $698,813 in total.
• RAP for a high earner: at $180,000 with 3% raises, the payment starts at $1,500 and climbs past the interest. The loan pays off around month 355, after about $835,000 in payments. Nothing is left to forgive.

RAP is a safety net for low income years and a path to PSLF. For a private-practice associate earning well, 30 years of it usually costs more than a refinance, even in today’s dollars. The refinance vs forgiveness tool compares the two with your numbers.

When not to use any of these timelines

• You’re in residency. RAP’s interest waiver usually beats a resident refinance. See Refinancing during residency.
• You owe several times your income. RAP forgiveness, even after the tax, can cost less. See When refinancing is a mistake.
• You might work for the VA, the military, a dental school or an FQHC. Keep the loans federal until you know.

How to pick your timeline

1. Rule PSLF in or out. If a qualifying employer is realistic, stop here and read Refinance vs PSLF vs RAP.
2. Run your numbers. Put your balance, rate and income in the refinance vs forgiveness tool.
3. Pick the payment you can carry in a bad year, not a good one. For most associates, that points to 10 years with extra payments rather than a 5-year sprint.
4. Choose fixed or variable. For a 10-year plan, fixed is usually the safer bet. See Fixed or variable rate when refinancing.
5. Check at least three lenders with soft pulls. A marketplace such as Credible shows several at once. The lender comparison covers the rest.
6. Compare rates before bonuses. An eighth of a point is usually worth more than a sign-up bonus. See Refinance bonuses: how they work.
