About Student Loan Calculator
Student loans are a significant financial commitment that can impact your finances for decades. Understanding your repayment options and how different plans affect your monthly payment and total cost is crucial for making informed decisions.
This calculator helps you explore different repayment strategies and see exactly how your loan terms affect your payment obligations and total interest paid.
Student Loan Repayment Plans
Standard Repayment Plan
Fixed monthly payments over a set period (typically 10 years). This is the most common plan and usually results in the lowest total interest paid.
Best for: Borrowers who can afford fixed payments and want to minimize interest
Graduated Repayment Plan
Payments start low and increase every 2 years, typically over 10 years. Total interest is usually higher than standard plan.
Best for: Borrowers expecting income to increase over time
Income-Driven Repayment Plans
Monthly payments based on discretionary income (typically 10-20% of discretionary income). Loan term can extend to 20-25 years. Remaining balance may be forgiven after the repayment period.
Best for: Borrowers with low income or high debt-to-income ratios

Student Loan Formulas
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where: M = Monthly payment, P = Principal, r = Monthly interest rate, n = Number of payments
Graduated Repayment:
Starts with lower payment, increases 10-15% every 2 years
Income-Driven Repayment:
Monthly Payment = (Discretionary Income) × (Percentage: 10-20%)
Discretionary Income = Adjusted Gross Income - 150% of Poverty Line
