Shared payment history

Calculate a split above, then record each month’s actual payments to the lender. The saved month keeps the planned shares you used at the time. Use the same person numbers throughout.

Keep the history on this device. You can view, edit or remove saved months here and export or clear saved data from My Borrowing Plan. Leave out account details.

How the split works

For a $480 monthly payment and a 60/40 split, the planned shares are $288 and $192. If the first person has $250 available and the second has $192, the next payment is $38 short.

The planner splits the monthly payment and upfront costs separately. If rounding leaves spare cents, it assigns them to the largest fractional shares, with earlier rows breaking ties. It projects the same rounded monthly split across the remaining payments. The next-payment check uses the cash entered for that payment and leaves the longer-term plan in place.

These amounts are for budgeting. Check the signed agreement for each borrower’s obligations and ask the servicer how it accepts payments. The CFPB explains the repayment responsibilities of an auto loan co-signer.

The calculation and CSV run in your browser. Only the months you choose to save are stored on this device.
