Sometimes a loan's terms need fixing after the fact. The interest rate was mistyped, the term should have been sixty months instead of forty eight, or the two of you agreed the loan is now five years instead of ten. Family Loan Tracker has a Manage loan option for exactly this, and it uses the same fields as setting up a loan in the first place.

What Manage loan is for

Manage loan corrects the loan's core terms as if they had always been that way. It recalculates the whole schedule from the new values, so it is not the place to record a rate that changes on a specific future date. If you need that, a variable rate that steps up next January, for example, that is not supported yet.

Opening it

  1. Go to the loan's page.
  2. Click Manage loan next to the loan name, the cogwheel icon.
  3. Update the fields you need to change.
  4. Check the box confirming you understand the schedule recalculates.
  5. Click Save changes.

The Manage loan modal showing principal, interest rate, and the Set term / Set payment toggle

What you can always change

Principal is the total amount borrowed, or the credit limit if the loan is a line of credit. Interest rate is the annual rate as a percentage; if you raise or lower it, it is worth checking the loan still clears the IRS minimum rate for its term. Duration uses the same Set term / Set payment toggle as loan creation: type the number of months and the tool works out the payment, or type the payment you want and it works out the term. Extra payment strategy controls whether extra payments shorten the loan or lower the next payment; nothing is stored against this choice, it is recalculated on every visit. Disbursement date, when the money actually went out if that differs from the first payment date, is also always editable; it only affects grace period interest between disbursement and the first payment.

What locks once a payment exists

Payment frequency and the first payment date can only change while the loan has zero recorded payments. Each payment is tied to a specific due date, so moving those dates after payments exist would leave old payments pointing at due dates that no longer line up with the schedule. Record even one payment and the modal disables both fields.

The rest of the Manage loan modal: payment frequency, dates, and the confirmation checkbox

What is not editable here

Currency is not one of the fields Manage loan can change. If a loan was set up in the wrong currency, the current fix is to delete it and create it again in the right one.

Before you save

The modal shows the effect of your change, the new monthly payment and new total interest, before you commit, and asks you to confirm you understand the schedule recalculates for both sides. Saving also emails the other party a summary of what changed, so nobody is surprised the next time they check the loan. That matters more than it sounds: a family loan holds up as a real loan partly because both sides can always see the same, current numbers, not a version each of you half remembers.

Renaming a loan or changing reminders

The pencil icon next to the loan name renames it. The bell icon opens reminder settings for that loan. Both live in the same header as Manage loan, but they are separate, smaller actions that do not recalculate anything.

If the terms changed because the two of you sat down and renegotiated rather than corrected a typo, our guide to planning a family loan covers how to have that conversation before you touch the numbers.

FAQ

Can I change the interest rate on a loan that already has payments recorded?

Yes. Interest rate, principal, duration, and extra payment strategy can all change at any time, even after payments exist. What locks is payment frequency and the first payment date, and only once at least one payment is recorded.

Why can't I change how often payments are due?

Because every payment already recorded is tied to a specific due date. Changing the frequency after payments exist would leave those payments pointing at dates that no longer match the new schedule, so the app blocks it until none are recorded.

Does the other person get told when I change the terms?

Yes. Saving a change emails the other party a summary of what changed, from the old value to the new one.

Can I change the currency after creating a loan?

Not yet. Currency is not one of the fields Manage loan can update. If you set up a loan in the wrong currency, delete it and create it again in the correct one.

What happens to payments I already recorded if I edit the terms?

They stay attached to the loan. Because Manage loan treats the new values as if they had always applied, the whole schedule recalculates around your recorded payments rather than replacing them.

Can I schedule a rate change for a future date instead of changing it now?

Not yet. Manage loan corrects the terms as if they had always been this way and recalculates the full history. A dated change that only applies going forward, a rate that steps up next year for example, is not supported at the moment.
