Teacher Loan Forgiveness Calculator

Teachers have access to two federal forgiveness programmes with different rules, different amounts and — critically — different definitions of the same words. Choosing the wrong one, or stacking them incorrectly, costs years.

The Two Programmes

	Teacher Loan Forgiveness	Public Service Loan Forgiveness
Service required	5 consecutive years	10 years (120 payments)
Amount forgiven	Up to $17,500	Entire remaining balance
Eligible schools	Low-income schools only	Any government or 501(c)(3)
Subject matters	Yes — the $17,500 tier requires maths, science or special education	No
Loan types	Direct and FFEL	Direct only
Taxable	No	No

The $17,500 tier is restricted. Most teachers qualify for $5,000, and the higher amount requires teaching secondary mathematics or science, or special education.

They Do Not Stack the Way People Assume

Years counted toward Teacher Loan Forgiveness cannot also count toward PSLF. Serving five years for a $17,500 forgiveness and then starting PSLF means fifteen years total rather than ten.

For a teacher with a large balance, going straight to PSLF is usually worth far more: $17,500 against a forgiven balance that can be several times that.

PSLF Requires Everything to Line Up

Four conditions, all simultaneously: a Direct loan, an income-driven repayment plan, full-time employment at a qualifying employer, and 120 qualifying payments. A payment made while any one of those is false does not count, and the most common cause of a rejected application is years of payments on the wrong plan.

Submit the Employment Certification Form annually rather than at the end. It is the only way to find out early that something has not been counting.

Perkins Cancellation

Older Perkins loans have their own teacher cancellation schedule, forgiving a percentage per year of service up to 100%. It is separate from both programmes above and frequently forgotten by borrowers who consolidated away from it.

Where the Money Goes

On $250,000 at 6.5% over 30 years, paying $1,580 a month:

Point	Principal repaid	Interest paid	Balance
Year 3	$8,957	$47,929	$241,043
Year 8	$26,123	$116,092	$223,877
Year 15	$68,602	$215,828	$181,398
Year 23	$137,677	$288,969	$112,323
Year 30	$250,000	$318,861	$0

Early payments are mostly interest. That is not a fee structure — it is arithmetic: interest accrues on the outstanding balance, which starts at its largest. It is also why an extra payment made early saves far more than the same payment made late.

What a Rate Change Costs

Rate	Monthly	vs 6.5%	Total repaid
5.50%	$1,419	-$161	$511,010
6.00%	$1,499	-$81	$539,595
6.50%	$1,580	—	$568,861
7.00%	$1,663	+$83	$598,772
7.50%	$1,748	+$168	$629,293

Half a percentage point moves the monthly payment by $83 and the total by $29,911. Shopping three lenders usually beats any amount of negotiating on price.
