The Loan Wizard helps you to calculate the split in each monthly repayment between
Interest portion which is an Expense to the Business
Capital Portion which is a reduction in the Liabilities of the Business
Total Repayment charged to the Bank Account
Please note that the Budget will show the movements in the Balance Sheet accounts, rather than the closing balances.
To see the results of these budgeted amounts, review the P&L with Projected Total, and the Balance Sheet with Projected Total, and you will see the Interest costs for the period, and the reducing balance in the Loan account for the period.
