Should I pay off my student loans or wait for forgiveness?

If your plan payment does not cover the interest, waiting is usually right, the balance grows until it is written off, and paying extra reduces a number that was going to be erased. If your payment clears the balance well before the forgiveness date, the plan gives you nothing and paying it off is better. The calculator identifies which case you are in from your own figures.

What is the student loan forgiveness tax bomb?

Most income-driven forgiveness is treated as ordinary income in the year it happens, so a forgiven balance of $150,000 in a 22% bracket produces a bill of around $33,000, due in cash, in one year, on money you never received. The calculator shows the bill and whether the money you saved under the plan covers it. Public service forgiveness is generally not taxed federally.

What does it mean if my balance is growing?

That your payment is below the monthly interest, so the shortfall is added to the balance. It looks alarming and, on a path to forgiveness, largely is not, the growing number is the one being written off. It matters a great deal if you later leave the plan, because you then owe the larger balance.

Should I refinance my student loans to a lower rate?

Not if forgiveness is plausible. Refinancing federal loans with a private lender permanently forfeits access to income-driven plans, forgiveness and federal protections, in exchange for a rate that this comparison shows is rarely the deciding factor. Refinancing suits borrowers who will clear the balance anyway and want it cheaper.

Should I save for the tax bill instead of paying extra?

Yes, if you are heading for taxable forgiveness. Money set aside earns a return and is available for the bill when it lands; money paid onto a balance that will be forgiven is simply gone. The savings column tracks that, and the calculator flags when what you have set aside falls short of the bill.

What about other debts while I do this?

Higher-rate debt usually deserves the spare money first, a credit card at 20% beats almost any student loan consideration. Snowball versus avalanche orders them, and taking the 401(k) match beats both if one is on offer.

Should I Pay Off Student Loans or Wait for Forgiveness?

Should I pay off student loans or wait for forgiveness? Two things decide it, and neither is the interest rate: whether your payment covers the interest, and whether the forgiven balance will be taxed. If it does not, the balance grows for twenty years and paying extra is money thrown at a debt that was never going to be repaid.

What this result assumes

Both paths spend $1,093.26 every month. The plan asks for less, so the difference is saved rather than spent, which is also how the tax bill gets paid.
Plan mechanics are entered rather than hard-coded, because the named federal programmes and their terms change often enough that a built-in version would be wrong within a year or two. Read the share, the exempt amount and the forgiveness period off your own paperwork.
Income grows at a constant rate, and the payment is recalculated once a year from it. Family size, filing status, spousal income and the annual recertification that can change your payment are not modelled.
Your payment does not cover the interest, so the balance grows every month until it is written off. On this path, paying anything extra is money thrown at a debt that was never going to be repaid.
The forgiven balance is treated as taxable income, producing a bill of $29,373 due in a single year. That is the risk this route carries, and preparing for it is what the savings column is for.

Methodology

Reviewed September 1, 2026

Two things decide this, and the interest rate is neither

The first is whether your plan payment covers the interest. On a large balance against a modest income it often does not — the default scenario here accrues about $538 a month and asks for $329 — and when that happens the balance grows every month for twenty years until it is written off. On that path the loan was never going to be repaid, and any extra dollar you throw at it is a dollar spent reducing a number that was going to be erased anyway.

The second is whether the forgiven balance is taxed. Most income-driven forgiveness is treated as ordinary income in the year it lands, which turns a six-figure write-off into a five-figure bill payable in cash, in one year, on money you never received. Public service forgiveness is generally not taxed federally, which changes the arithmetic completely — hence the toggle.

Neither of those turns on the interest rate, which is why the usual advice about refinancing to a lower rate can be actively wrong here: refinancing a federal loan privately forfeits access to the plan and to forgiveness entirely.

How the comparison is held fair

Both paths spend the same amount every month — the larger of the standard payment and the plan payment. The plan asks for less, so the difference is saved and invested rather than quietly disappearing, which is both the honest treatment and, in practice, exactly how the tax bill gets paid.

The standard path runs through the same amortisation engine the rest of the site uses, so its final payment absorbs the rounding remainder and the balance lands on exactly zero. Once it clears, the whole budget is saved for the remaining months, so neither path is credited with money the other never had.

Net worth at the forgiveness date is savings less any tax due. That is what the two paths are compared on, rather than total dollars paid — a figure that ignores what the lower payment let you do with the difference.

Why the plan terms are inputs, not built in

The named federal programmes and their terms change often. Payment shares, protected income amounts, forgiveness periods and the tax treatment of forgiveness have all moved in recent years, and several are subject to litigation and rulemaking as this is written. A calculator with one plan hard-coded into it would be quietly wrong within a year or two, and quietly wrong is the worst kind.

So the mechanics are exposed instead: the share of discretionary income the plan takes, the amount of income it protects, how long until forgiveness, and whether that forgiveness is taxed. Read those four figures off your own plan’s paperwork or your servicer’s account page and the model follows whatever plan you are actually on.

What it does not model is the annual recertification, family size, filing status or a spouse’s income — all of which move a real income-driven payment. Treat the projection as the shape of the decision rather than a forecast of your statement.

Assumptions

Both paths spend the same amount each month; the difference under the plan is saved and invested.
The plan payment is a fixed share of income above a protected amount, recalculated once a year.
Income grows at a constant rate, and family size, filing status and spousal income are not modelled.
Interest accrues monthly on the balance and is capitalised into it when unpaid.
Any interest subsidy some plans offer on unpaid interest is not modelled, which overstates balance growth on those plans.
The forgiven balance is taxed at your marginal rate in a single year, if taxable.
State tax on forgiveness is excluded; several states tax it even when the federal government does not.
The standard path makes level payments to a full payoff with no deferment or forbearance.
Savings are taxed annually on gains at your marginal rate.
The plan remains available and its terms unchanged for the whole period, which is the largest assumption here.
