Standard Monthly Payment

About the Student Loan Calculator

This student loan calculator computes standard monthly payments and also provides income-based repayment (IBR) estimates. Understanding your repayment options is crucial for managing student loan debt effectively after graduation. Student loans are unique because they offer income-driven repayment options that can make payments more manageable based on your earnings. This calculator helps you compare standard repayment with income-based repayment, showing potential savings and forgiveness scenarios.

How to Use This Calculator

  1. Enter your total loan amount, average interest rate, and repayment term.
  2. Optionally enter a custom monthly payment to see how extra payments accelerate payoff.
  3. Enter your income and family size to estimate IBR payments and potential savings.

The Formula

The standard repayment uses the amortization formula. IBR is calculated as 10% of discretionary income (income above 150% of poverty guidelines).

IBR Payment = 10% × max(0, Income - 1.5 × Poverty Guideline) / 12

Frequently Asked Questions

What is income-based repayment?

IBR caps your monthly student loan payment at a percentage of your discretionary income. After 20-25 years of qualifying payments, any remaining balance may be forgiven.

Should I pay extra on my student loans?

Paying extra reduces total interest and speeds up payoff. However, if you qualify for loan forgiveness through IBR or PSLF, paying the minimum may be more beneficial.

What is income-based repayment (IBR)?

IBR caps your monthly payment at 10-15% of your discretionary income (income above 150% of poverty guidelines). After 20-25 years of qualifying payments, any remaining balance may be forgiven.

Should I choose standard or income-driven repayment?

Standard repayment has higher payments but less total interest. Income-driven repayment lowers monthly payments but may result in more interest over time. Choose based on your income and career trajectory.

Can I make extra payments on my student loans?

Yes, you can always pay more than the minimum on federal and private student loans without penalty. Extra payments reduce principal faster and save interest.

What happens if I do not pay my student loans?

Defaulting on student loans has serious consequences including wage garnishment, tax refund seizure, damaged credit, and loss of eligibility for future financial aid and deferment options.
