Loan Log and Tracker
Add each loan to calculate its monthly payment and total interest, build your full portfolio, and export to CSV. No data leaves your device.
Why Track Your Student Loans
This tool lets you save multiple loan scenarios, export them to CSV, and watch your payoff progress in one place. Tracking turns vague worry into a concrete plan you can act on.
Saving scenarios
Before you refinance, make an extra payment, or change plans, save the current scenario. Later you can compare "before and after" to see exactly what a decision changed in dollars and months. Scenarios are stored in your browser, so nothing leaves your device.
Exporting to CSV
Export your loans to a spreadsheet for deeper analysis or a permanent record. CSV opens in Excel, Google Sheets, or any spreadsheet app, so you can chart balances over time or share with a financial counselor.
Tracking progress
Record your balance after each payment. Watching the line go down is motivating, and it helps you catch servicer errors early. If a payment didn't reduce principal as expected, you can investigate before it compounds.
Using the log for refinance decisions
Keep a log of your current loans beside any refinance offer. The comparison shows whether the new rate truly saves interest after fees. Don't refinance federal loans blindly—log them separately so you remember which protections you'd give up.
Managing multiple loans
List every loan with its rate and balance. The log makes the avalanche vs. snowball choice obvious: highest rate (avalanche) or smallest balance (snowball) comes first. Re-sort whenever a loan is paid off.
Privacy note
All data stays in your browser's local storage. StudLoanCalc does not collect, transmit, or store your loan details on any server—enter real numbers with confidence.
Frequently Asked Questions
Yes. Scenarios are saved only in your own browser's local storage. Nothing is uploaded or shared with us or any third party.
Clearing cache can delete locally stored scenarios. Export to CSV first if you want a permanent backup.
Yes. Add each loan as its own entry regardless of servicer; the log totals and ranks them together.
After each monthly payment, or monthly at minimum. Regular updates keep your progress chart and payoff estimate accurate.
It exports the loan entries and current values you have entered. Add periodic snapshots yourself to build a history over time.
It is a planning aid, not a record of official payments. Always confirm balances and qualifying-payment counts with your servicer.

Getting the Most from Your Loan Log
Do an annual loan review
Once a year, export your CSV and check each loan's rate, balance, and servicer. Rates and servicers change; an annual review catches a loan that has crept up in rate or a refinance opportunity you'd otherwise miss.
Pair the log with your budget
Your loan log shows the debt side; your budget shows the cash flow side. Together they answer "how much extra can I safely send?" without guessing. Log the extra amount you commit to, then watch the payoff date move up.
Catch servicer errors early
Recorded balances make discrepancies obvious. If a payment didn't reduce principal as expected, or interest looks too high, you have a dated log to dispute from. Small errors caught early don't compound.
Share with a counselor
Exported CSV is easy to hand a nonprofit credit counselor or financial planner. They can spot a better plan (an IDR switch, a refinance, a PSLF path) far faster with your real numbers in front of them.
Plan your long-term finances
Once loans are logged, you can model trade-offs: pay extra vs. invest, refinance vs. stay federal, attack highest rate vs. smallest balance. The log turns "I think I'm doing okay" into a number you can defend.
Case study: the forgotten loan
Illustrative: A borrower with four loans logged them all and discovered one small private loan at 9% hiding among federal ones. By redirecting extra payments there first (avalanche), they saved more than the larger federal loans would have—something they'd never have seen without the log.
Keeping it private and permanent
Local storage keeps your data on your device, but it isn't a backup. Export to CSV whenever you make a big change so a cleared cache or new device doesn't lose your history.
More Log Questions
All of them—federal and private, even small ones. The full picture is what makes the avalanche vs. snowball and refinance decisions correct.
Yes; logging the household together helps rank by rate. Just remember which loans are legally each person's if you ever separate finances.
No. Use the log for planning; trust the servicer for official balances and qualifying-payment counts, and reconcile the two periodically.
That's exactly when the log helps most—enter each loan once, regardless of servicer, and see the whole portfolio in one view.
Your Loan-Log Checklist
- Log everything: every federal and private loan, with rate and balance.
- Export to CSV after any big change for a permanent backup.
- Update monthly after your payment posts.
- Reconcile your log against servicer statements each year.
- Save scenarios before refinancing or changing plans to compare before/after.
- Rank by rate to decide avalanche vs. snowball at a glance.
Pair the Log with Other Tools
Your log is the data layer. Feed it into the calculators: the Amortization Calculator shows a single loan's schedule, the 5-Plan Comparison models repayment plans, the Debt Payoff tool applies avalanche or snowball, and the PSLF Calculator estimates forgiveness. The FAQ answers quick questions, and the blog explains the policies behind the numbers.
Make It a Habit
Set a recurring monthly reminder to update balances. Ten minutes a month turns vague anxiety into a plan you control—and catches errors, rate changes, and refinance opportunities while they still matter. Because all data stays in your browser, you can be thorough without sacrificing privacy.
Bottom Line
You cannot manage what you don't measure. Logging every loan—federal and private—turns anxiety into a plan: you see which debt to attack first, whether a refinance truly helps, and how your balance moves month to month. Export to CSV for a permanent backup, update monthly, and reconcile against your servicer once a year. Because everything stays in your browser, you get full visibility with no privacy cost. Feed the log into the Amortization Calculator, 5-Plan Comparison, Debt Payoff, and PSLF Calculator, check the FAQ for quick answers, and explore the blog for the policies behind the numbers. Ten minutes a month is all it takes to stay in control.
Data Security and Final Tips
Your loan details are stored only in this browser's local storage and are never sent to any server. That keeps your financial data private, but it also means the data lives on this device and browser. If you switch devices, clear your cache, or use private browsing, your saved scenarios won't follow you—so export to CSV whenever you make meaningful progress.
Treat the log as your single source of truth for planning, while your servicer remains the source of truth for official balances and qualifying payments. Reconciling the two yearly catches drift early. Over time, the habit turns student debt from a looming unknown into a number you control, with a clear date on the calendar when it ends.
Your Annual Review Routine
Once a year, sit down with your exported CSV and ask four questions: (1) Did any rate change, and should I refinance the high-rate portion? (2) Has my income shifted enough to change my IDR payment? (3) Am I still on track for PSLF if I'm pursuing it? (4) Which debt should be the target next month? Writing the answers beside your log turns a vague yearly worry into a concrete set of actions. Do this in the same session you recertify any IDR plan, and the two reviews reinforce each other—one confirms your payment, the other confirms your strategy.
Why Borrowers Lose Track (and How the Log Helps)
Student debt is easy to ignore because payments are automatic and balances shift slowly. Months pass with no drama, then a rate change or servicer transfer surfaces an error that has been compounding quietly. The log breaks that invisibility: a two-minute monthly update makes the trend impossible to miss. Borrowers who track also negotiate better, because they walk into a refinance or IDR conversation with exact numbers instead of guesses. The goal isn't perfection—it's a habit simple enough to keep, which is why local, private, exportable tracking beats an elaborate system you abandon after a week.
