**Keep enough debt to receive the employer payments for as long as you expect to stay. A partial payoff can improve the result, provided it leaves enough balance to preserve those payments.**

Assuming the employer’s $200 satisfies your monthly minimum and you owe no separate payment, your current monthly math is approximately:

| Item | Monthly amount |
|---|---:|
| Employer contribution | +$200 |
| Loan interest | −$50–$60 |
| Interest earned on $17,000 at 2% | +$28 |
| Benefit of keeping the loans versus paying everything off | **+$168–$178** |

These figures are before taxes. Paying everything off would surrender a substantial benefit.

**The partial-payoff decision depends on your expected time at this job.** Every dollar you repay saves loan interest but gives up savings-account interest. For example, paying down a 4.5% loan with cash earning 2% produces an initial annual benefit of approximately 2.5% of the amount repaid, before taxes. That helps while you continue receiving the same employer contribution. Once the loans reach zero, the contribution stops.

A practical approach is:

- **If you expect to leave in about a year:** Leave roughly $2,400–$2,600 outstanding and pay down the rest, starting with the highest-rate loans. For illustration, a $2,500 balance at 4.5% supports twelve full $200 monthly payments and leaves a small balance afterward.
- **If you expect to stay several years:** Leave enough debt for that longer period—roughly $200 multiplied by the number of months, with interest allowing a somewhat smaller starting balance.
- **If your departure date is uncertain:** Keep a larger balance and reassess periodically. Paying down too much could exhaust the benefit while you still work there.

Preserve your emergency fund when choosing the lump sum. For any extra payment, direct it toward the highest-rate loan after satisfying the required payments on all four loans. The [CFPB recommends that allocation to maximize interest savings](https://www.consumerfinance.gov/paying-for-college/repay-student-debt/student-loan-debt-tips/).

Before making a large payment, verify that the employer continues paying when your account is “paid ahead,” that its payment satisfies your required installment, and that the benefit continues with just one eligible loan remaining. Those details determine whether this strategy works.

When you leave, compare the remaining loans’ rates with your **after-tax** savings return. Paying off loans charging more than that return generally makes financial sense, assuming you retain adequate cash reserves.

Your credit score should be a secondary consideration. Student loans are installment accounts; paying off your last active installment loan can lower your FICO score, with the effect depending on the rest of your credit profile. [FICO explains this effect here](https://www.myfico.com/credit-education/faq/scores/paying-off-installment-loan). An upcoming mortgage application could make the timing relevant, but I would base this strategy primarily on the employer benefit and interest costs.

And yes, the interest variation is expected: federal student-loan interest accrues daily, so the number of days between payments affects how much goes to interest. [Federal Student Aid explains the calculation](https://studentaid.gov/understand-aid/types/loans/interest-rates).
