If you are pursuing Public Service Loan Forgiveness (PSLF), one of the most important things to understand is how much you’ll pay each month under an income-driven repayment (IDR) plan. Since payments are based on your income, family size, and poverty guidelines, it can be confusing to estimate your monthly bill.
PSLF Monthly Payment Calculator
hat is the PSLF Monthly Payment Calculator?
The PSLF Monthly Payment Calculator is a free online tool that helps borrowers estimate their student loan payments under PSLF. It uses three main inputs:
- Annual Income – Your adjusted gross income (AGI).
- Family Size – The number of people in your household.
- Poverty Guideline Percentage – Usually set at 150%, based on federal poverty guidelines, but adjustable in this calculator.
With these inputs, the calculator determines:
- Discretionary income (the amount of income above the poverty threshold).
- Estimated monthly payment (10% of discretionary income, divided by 12).
How the PSLF Calculator Works
The math behind PSLF payments is straightforward once you understand the formula:
- Find the poverty line:
- Base amount = $14,580 for a household of 1 (2023 guideline).
- Add $5,140 for each additional family member.
- Apply the poverty percentage:
- Default is 150%, but some plans may vary.
- Calculate discretionary income:
- Annual income – (poverty line × poverty percentage).
- Determine monthly payment:
- 10% of discretionary income ÷ 12 months.
The calculator automates all of this, giving you instant results.

- Use your most recent tax return (Adjusted Gross Income).

Example PSLF Payment Calculation
Let’s walk through an example to show how the calculator works.
- Annual income: $50,000
- Family size: 3
- Poverty guideline (150%): $14,580 + ($5,140 × 2) = $24,860 × 1.5 = $37,290
- Discretionary income: $50,000 – $37,290 = $12,710
- Monthly payment: ($12,710 × 10%) ÷ 12 = $105.91
👉 In this example, the borrower’s estimated PSLF monthly payment would be $105.91.
