Student loan consolidation is a process that combines multiple federal student loans into a single, new loan with a new interest rate. Private student loan consolidation (often referred to as refinancing) can combine multiple private loans, or a mix of federal and private loans, into a new private loan. This calculator helps you understand the potential financial impact of consolidating your student loans, focusing on the change in interest rates and monthly payments.
How it Works
When you consolidate federal loans, the new interest rate is typically a weighted average of your existing loans' rates, rounded up to the nearest one-eighth of a percent. Private refinancing offers more flexibility, allowing lenders to set rates based on your creditworthiness, potentially leading to lower rates than your current average.
Key Factors to Consider:
Interest Rate: A lower interest rate on your consolidated loan means less money paid in interest over the life of the loan.
Monthly Payment: Consolidating can lower your monthly payments, freeing up cash flow. However, be aware that extending the loan term to lower monthly payments can sometimes result in paying more interest overall.
Loan Term: The duration of your loan. A shorter term means higher monthly payments but less total interest paid. A longer term means lower monthly payments but more total interest paid.
Loan Type: Federal loan consolidation offers certain benefits (like access to income-driven repayment plans and public service loan forgiveness) that are lost if you consolidate federal loans into a private loan. Private refinancing does not preserve these federal benefits.
Calculator Logic Explained:
This calculator provides an estimated comparison based on the inputs you provide. Here's a breakdown of the calculations:
Estimated Total Interest Paid (Current): This is calculated based on the total loan balance, the average interest rate, and an estimated loan term derived from your current total monthly payment. The formula is an approximation, but gives a general idea: Total Interest = (Monthly Payment * Number of Months) - Total Loan Balance, where Number of Months = Total Loan Balance / Monthly Payment.
Estimated Total Interest Paid (Consolidated): This is calculated similarly to the current interest, but uses the proposed consolidated monthly payment and the consolidated interest rate. An adjusted loan term is calculated: Number of Months (Consolidated) = Total Loan Balance / Consolidated Monthly Payment.
Estimated Savings: The difference between the total interest paid on your current loans and the total interest paid on the consolidated loan. Savings = Total Interest (Current) - Total Interest (Consolidated).
Note: This calculator provides an estimate. Actual savings may vary depending on the exact loan terms, fees associated with consolidation, and how quickly you pay down the loan.
When to Consider Consolidation:
You have multiple student loans with varying interest rates and want to simplify payments.
You can secure a lower interest rate through consolidation, significantly reducing the total interest paid.
You need to lower your monthly payments to improve your budget, and you are comfortable with a potentially longer repayment term (and possibly higher total interest).
You have private loans that you want to bundle together for easier management.
Important Considerations:
If you have federal student loans, carefully weigh the benefits of consolidation (simplicity, potentially lower rate) against the loss of federal benefits like income-driven repayment plans, deferment, forbearance options, and forgiveness programs (like Public Service Loan Forgiveness). Refinancing federal loans into a private loan permanently eliminates these federal protections.
