Coast FIRE With Student Loans
Student loans can affect Coast FIRE through monthly cash flow, retirement contributions and the date the loans end. Model those effects separately without automatically subtracting your loan balance from retirement investments.
Your Coast FIRE + Student Loan Plan
Do not include student loan payments here. The calculator models them separately.
Use the age when you expect payments to end through payoff, forgiveness or another repayment outcome.
Student Loan Details & Repayment PathConfigure loan balance, interest rate, type, and repayment path
Pay Off Student Loans From InvestmentsOptionally withdraw assets to pay off loan principal
If student debt is paid off from investments, Current Investments are reduced once and future payments associated with that amount are removed. Never subtract the loan balance AND continue modeling the same loan payments.

A Student Loan Payment Does Not Always Increase Your Coast FIRE Number
If the loan will be paid off before retirement, the payment is primarily a current cash-flow issue. It can reduce how much you contribute today without becoming a permanent retirement expense.

Does Your Employer Match Student Loan Payments Into Retirement?
Some workplace retirement plans may treat qualified student loan payments as eligible for employer matching contributions (IRS Notice 2024-63 / SECURE 2.0). Availability depends on your employer's specific plan document.
Can You Reach Coast FIRE With Student Loan Debt?
Coast FIRE compares the retirement portfolio with the amount needed today to reach the retirement target. Student loan debt does not automatically erase retirement investments. Instead, loans can affect the plan through monthly cash flow, retirement contributions, loan payments that overlap retirement, or an explicit payoff from investments.
Student Loan Payoff and Coast FIRE Are Different Milestones
A borrower might reach Coast FIRE first and repay student loans later, repay loans first and reach Coast FIRE later, or reach both around the same time. Neither milestone should be silently substituted for the other. The timeline shows both dates clearly.
Federal and Private Student Loans Need Different Inputs
Federal student loans offer income-driven repayment plans and forgiveness programs that private student loans generally do not replicate. For federal loans, use your Federal Student Aid Loan Simulator output. For private loans, use your lender's actual payment, rate, and payoff schedule. Note: the Consumer Financial Protection Bureau warns that refinancing federal student loans into private loans permanently removes federal repayment options and borrower protections.

Questions About Coast FIRE With Student Loans
Answers to common questions about student debt, payoff timing, PSLF, employer matching, and extra payments.
Do I subtract my student loan balance from my Coast FIRE investments?▼
Not automatically. Student loans are a liability, while Current Investments represents assets modeled toward retirement. Reduce investments only when the scenario actually uses those assets to repay the loan.
Can I reach Coast FIRE while I still have student loans?▼
Yes as a modeled result. Coast FIRE and student-loan payoff are separate milestones. The important questions are whether loan payments affect current contributions and whether payments continue into retirement.
Should student loan payments be included in my retirement spending?▼
Only for retirement years when payments are expected to continue. If the loans end before retirement, treat them as current cash flow rather than permanent retirement spending.
What happens to Coast FIRE when my student loans are finally paid off?▼
The Coast target does not automatically change. If you redirect some of the former loan payment to retirement investments, the projected portfolio and modeled Coast date may change.
Should I pay extra on student loans or invest the extra money?▼
The calculator can compare both scenarios without recommending one. Additional loan payments affect debt payoff and interest, while additional investing uses an assumed and uncertain market return.
How should I model student loans if I am pursuing PSLF or another federal forgiveness path?▼
Use Federal Student Aid's current repayment tools to estimate the payment and expected end date, then enter those values here. Do not model the loan as a normal fixed amortizing debt unless that matches the actual plan.
Can student loan payments still generate an employer retirement match?▼
Some employers can provide retirement-plan matching contributions based on qualified student loan payments under SECURE 2.0 rules. Whether this is available depends on the employer's retirement plan.
