CSN student-loan repayment plan 2026
CSN issues an individual annual amount. Your loan type, balance, interest, age and remaining term can all matter. This calculator is therefore a planning model: it shows a conventional amortisation scenario and does not replace the payment plan CSN sends you.
The 2026 interest rate
CSN lists a 2.135% student-loan rate for 2026. The government sets the rate every year, so later years can differ. You can change the advanced rate field for a scenario. This planner does not assume an interest deduction for payments made from 2026.
How the model works
Enter the remaining balance, choose one to 25 years and select monthly or annual periods. The first payment uses a simplified amortising formula. An optional annual increase, such as 2%, raises the planned payment each year and usually shortens the payoff. Set it to zero for level payments.
Read the result as a comparison
The first monthly amount is a monthly comparison even when annual frequency is selected. The total sums the modelled payments until the balance is repaid or the selected term ends. The preview shows payment, interest and principal for the first five years.
Why your CSN amount can differ
CSN may account for age, loan type, earlier payments, new borrowing, income-based reductions and older loan rules. The annual amount can also change when the interest rate changes. Always check your current CSN payment plan before committing to a budget.
