Adjusted balance

An adjusted balance is a method of calculating interest charges or assessing fees on a credit account by taking the outstanding balance at the end of the billing cycle and subtracting payments and credits received during that period. This approach is most commonly used in certain credit card interest calculations, although it can also be applied in other lending products.

The adjusted balance method differs from other calculation methods because it does not include new purchases made during the current billing cycle when determining the balance subject to interest. Instead, it focuses on the balance carried over from the previous cycle, minus any payments or credits, before interest is applied.

In lending and consumer finance, understanding the adjusted balance method is important because it can have a significant impact on the cost of borrowing, especially for customers who make substantial payments within a billing cycle.

How the Adjusted Balance Method Works

When a lender or credit card issuer uses the adjusted balance method, the interest charge is calculated in a sequence of steps:

1. At the start of the billing cycle, the account has a certain balance carried over from the previous month.
2. During the billing cycle, the borrower may make payments or receive credits (for example, refunds).
3. At the end of the billing cycle, the lender subtracts these payments and credits from the starting balance to arrive at the adjusted balance.
4. New purchases made during the cycle are not included in this calculation for the current month’s interest. They will be considered in the next cycle if they remain unpaid.
5. Interest is applied to the adjusted balance at the account’s stated rate.

For example, if the starting balance is £1,000, and the borrower makes a £400 payment during the billing cycle, the adjusted balance is £600. If the monthly interest rate is 1.5%, the interest charge would be £9 (1.5% of £600), regardless of whether the borrower spent an additional £200 during the month.

Key Characteristics of the Adjusted Balance Method

The adjusted balance method has distinctive features compared to alternative calculation methods such as the average daily balance or previous balance methods:

• Payments made during the billing cycle directly reduce the balance on which interest is charged.
• New purchases do not increase the interest-bearing balance for the current cycle.
• It tends to result in lower interest charges for borrowers who make significant payments during the cycle.

Because of these characteristics, the adjusted balance method is often seen as more favourable to consumers than methods that calculate interest on balances before payments are applied.

Advantages for Borrowers

For borrowers, the adjusted balance method can be advantageous in several ways:

1. Encourages early repayment because payments made within the cycle lower the interest-bearing balance.
2. Offers potential savings on interest costs for those who regularly make partial or full payments before the end of the billing period.
3. Provides more transparent alignment between repayment behaviour and interest charges.

This can be particularly useful for disciplined borrowers who manage their credit proactively, making payments as soon as possible rather than waiting for the due date.

Impact on Lenders

From a lender’s perspective, using the adjusted balance method can be less profitable than other calculation methods because it reduces the interest revenue generated from customers who make frequent payments. However, it can be a competitive advantage when attracting and retaining customers, particularly in markets where borrowers compare credit terms closely.

Some lenders may offer the adjusted balance method as a customer-friendly feature, while others may reserve it for specific products aimed at financially responsible consumers or as part of promotional credit terms.

Comparison with Other Methods

To understand the impact of the adjusted balance method, it is helpful to compare it with common alternatives:

• Previous balance method: Interest is calculated on the balance at the start of the billing cycle, without considering payments or credits made during the cycle. This usually results in higher interest charges.
• Average daily balance method: Interest is calculated on the average of the balances for each day in the cycle, including new purchases and payments. This can either increase or decrease interest costs depending on the borrower’s spending and repayment patterns.

The adjusted balance method typically yields lower interest charges than the previous balance method and can be similar to or slightly better than the average daily balance method for borrowers who make early or mid-cycle payments.

Adjusted Balance in the Lending Industry

In the lending industry, the adjusted balance method is not limited to credit cards. It can also be applied in some personal loan and business credit products, particularly in revolving credit arrangements. In these cases, it provides a clear link between repayments made during the cycle and interest charges, encouraging timely payments and potentially reducing default risk.

For lenders, this method can be part of a responsible lending strategy, signalling to customers that repayment discipline is rewarded. However, it may not be used for all loan types because it reduces the amount of interest income compared to other methods.

Regulatory Considerations

In the United Kingdom, lenders must disclose the method used to calculate interest under consumer credit agreements. This requirement ensures transparency and allows customers to compare products fairly. For credit cards, lenders must also provide illustrative examples of interest charges in the summary box format mandated by the Financial Conduct Authority (FCA).

Borrowers are entitled to clear information on how their interest will be calculated, including whether new purchases are excluded from the current cycle’s interest calculation under the adjusted balance method.

Practical Tips for Borrowers

Borrowers who have accounts using the adjusted balance method can minimise interest charges by:

• Making payments as early as possible in the billing cycle.
• Avoiding carrying a balance from one month to the next, where possible.
• Understanding the cut-off date for the billing cycle to ensure payments are applied before the interest calculation date.

By following these practices, borrowers can take full advantage of the benefits the adjusted balance method offers.

Conclusion

The adjusted balance method is a borrower-friendly approach to interest calculation that directly rewards timely payments by reducing the balance on which interest is charged. It is most commonly used in credit card accounts but can also be applied in other revolving credit products. While it may generate less revenue for lenders compared to other methods, it can serve as a valuable competitive feature and a tool for promoting responsible borrowing behaviour. For consumers, understanding how this method works can lead to significant savings and better overall credit management.
