$30,000 Student Loan: Monthly Payment
A $30,000 student loan at an illustrative 6% rate costs approximately $333 per month on a standard 10-year plan, generating about $9,960 in total interest. Shortening to five years raises the payment to roughly $580 but cuts total interest almost in half. Enter your own rate and term above for exact numbers.
New monthly payment
You pay today, so that is a month back in your pocket.
That is more than the you pay today — the shorter term costs more each month but clears the debt sooner.

At these numbers the new loan never pays for itself: the monthly payment does not fall.
Careful — the lower payment comes from a longer term. Over the full term this deal costs more than staying put.
Both loans are modelled as fixed-rate, fully amortising, with no missed months. A refinance replaces your loan with a brand-new private loan — see what that costs you below.

What you give up when federal loans go private
- Income-driven repayment. A private lender sets one payment; it does not fall when your income does.
- Federal forgiveness programmes, including Public Service Loan Forgiveness and any income-driven forgiveness after the full repayment term.
- Federal discharge on death or total and permanent disability — private lenders decide their own policy.
- Federal deferment and forbearance rights, and the federal rehabilitation route out of default.
- The decision is one-way. Once a federal loan is refinanced privately, it cannot be turned back into a federal loan.
Refinancing private loans into a cheaper private loan gives up none of this — it is federal balances that carry the risk.
Comparing Terms on a $30,000 Balance
At an illustrative 6%, the 5-year plan demands approximately $580 per month but holds total interest near $4,800. The standard 10-year plan halves the payment to about $333 while pushing interest to roughly $9,960. A 15-year term drops the payment further to approximately $253 per month, but interest climbs to around $15,570. The gap between 5-year and 15-year total interest is more than $10,000 on the same $30,000 principal, which illustrates how dramatically term length affects cost.
For many borrowers, the 10-year plan represents the best compromise on a $30,000 balance: the payment is sustainable on a typical early-career salary, and the total interest cost stays below a full year's worth of the original balance. The refinance-savings calculator can show whether a lower rate would make the more aggressive 5-year payment more accessible for your budget.
Strategies for Paying Down $30,000 Faster
If you start on the 10-year plan and later find room in your budget, channelling extra dollars toward principal can deliver results approaching the 5-year schedule without the upfront commitment to the higher monthly payment. Even adding one extra full payment per year, whether as a lump sum or spread across 12 months as a small increment, can shorten a 10-year term by more than a year and save over a thousand dollars in interest at an illustrative 6% rate.
The $20,000 page and $40,000 page show how the same dynamics scale at neighbouring balances. If your $30,000 loan is federal and you are considering refinancing to a private lender for a better rate, remember that switching permanently removes access to income-driven repayment, forgiveness programmes, and federal forbearance protections. Use the calculator above to model different extra-payment amounts and see how quickly each one moves your debt-free date forward.
All figures assume an illustrative 6% rate with standard amortisation. Enter your actual rate above; even a fraction of a percent changes the totals meaningfully.
