Flexible loan calculator
Solve for the missing loan figure, then build the schedule
Enter the loan figures you know and choose the one to solve for: the amount, interest rate, number of periods, payment or residual. The flexible loan calculator works it out and builds a repayment schedule with a summary for each financial year.

What goes wrong today
The contract doesn’t state the rate
A finance agreement gives the amount, the repayments and the balloon, but not the interest rate you need for the accounts.
Year end needs a schedule, not one figure
Reconciling a loan for the tax work means every repayment split by financial year, which a one-line calculator doesn’t give you.
