This guide explains every number on your loan's dashboard in Family Loan Tracker — what it measures, how it's calculated, and what to do when one of them looks off.
Once a loan is set up, the dashboard becomes the single place both the lender and the borrower check to see where things stand. The numbers are designed to answer one question at a glance: is this loan on track? Here's how to read each piece.
The periodic payment amount
This is the amount due each payment period, based on the loan's principal, interest rate, duration, and payment frequency. For a fixed-rate loan, this number stays the same for the life of the loan unless an extra payment changes the remaining schedule.
If you see this number change partway through a loan, it usually means an extra payment was logged and the schedule recalculated — not an error.
Total interest
Total interest is the sum of all interest the borrower will pay over the full life of the loan, assuming payments are made on schedule. It's calculated up front from the loan terms, then revised any time the schedule changes.
For example, a $20,000 loan at 4% over 5 years with monthly payments has a total interest figure of a little under $2,100. That number drops every time an extra payment reduces the principal early, because less balance is outstanding to accrue interest against.
Paid principal and paid interest
These two cards track what has actually happened so far, as opposed to what's projected. Paid principal is the portion of all payments made to date that went toward reducing the loan balance. Paid interest is the portion that went toward interest cost.
Early in a loan's life, paid interest typically makes up a larger share of each payment than paid principal — this is normal amortization behavior, not a sign of bad terms. As the loan matures, the split shifts toward principal.
Overdue amount
The overdue card only appears when a scheduled payment has passed its due date without being recorded. It shows the total amount currently past due, summed across any missed payments. When a loan has no overdue payments, this card doesn't display at all — its presence is itself a signal.
If you've made a payment outside the app (cash, a bank transfer not yet recorded) but the dashboard still shows it as overdue, record the payment to clear the flag. The dashboard reflects what's been logged, not what's happened in real life until you log it.
The progress card
The progress card shows what percentage of the total loan has been repaid, measured by principal paid against original principal — not by the number of payments made. A loan that's 50% through its term by time but has received several extra payments may already show well over 50% progress.
This distinction matters because it's principal, not time, that determines when the loan is actually finished.
Reading the cards together
The dashboard is most useful read as a set rather than card by card. A loan with a steadily climbing paid-principal figure, no overdue amount, and a progress bar tracking close to the time elapsed is behaving exactly as planned. A loan with a growing overdue figure next to a progress bar that's lagging behind the elapsed term is the clearest early signal that a conversation with the other party is overdue too — before the gap widens. Our guide on common family loan mistakes covers how an ignored dashboard pattern like this one tends to play out if it isn't addressed early.
