How to use this calculator
Compare the projected total cost, not only the first monthly payment. Private student-loan terms can depend on school, program, co-signer and borrower profile.
How the student loan estimate works
The calculator first estimates simple interest during the entered period before repayment and adds that amount to the original principal once. It then applies a fixed-rate amortization formula across the repayment term. This produces an illustrative balance entering repayment, monthly payment, total repayment and total interest.
Example: interest before repayment
On a $30,000 balance at a 12% fixed APR, 12 months of simple accrued interest would be $3,600 in this model. If that interest is added to principal, repayment begins on an estimated $33,600 instead of $30,000. The actual lender may accrue or capitalize interest differently.
Why a private-loan disclosure can differ
A lender may use daily accrual, multiple disbursements, in-school payments, variable rates, fees or different capitalization events. The calculator also does not model deferment, hardship options or exchange-rate effects for a family paying from another country.
Co-signer and no-co-signer comparisons
A co-signer is legally responsible for the debt under the agreement, not merely a reference. A no-co-signer program can still have strict school, degree, visa and underwriting requirements. Compare the final APR, school eligibility, repayment start, co-signer release terms and borrower protections.
Federal Student Aid notes that most foreign citizens are not eligible for U.S. federal student aid, while some eligible noncitizens may qualify. Check current official eligibility guidance, your school’s aid office and our co-signer vs. no-co-signer guide before considering a private loan.
What the estimate cannot tell you
This tool does not access a credit report, verify income, collect identity information, predict approval or replace provider disclosures. Rates, fees, screening rules and eligibility are controlled by the relevant provider.
Frequently asked questions
Does the calculator support variable APR?
No. It holds the entered APR constant, so a variable-rate loan requires multiple scenarios and can change over time.
Is grace-period interest always capitalized this way?
No. The tool uses one simplified capitalization assumption; lender accrual and capitalization terms vary.
Does no co-signer mean guaranteed approval?
No. Providers can still evaluate school, program, identity, visa and financial information.
