Investments With Daily Compound Interest: Smart Money Moves

Daily compound interest is a method of calculating interest on a loan or investment that is added to the principal amount daily. This means that interest is calculated not only on the original principal but also on any previously accrued interest. As a result, the interest compounds over time, which can significantly increase the growth of the investment. The compounding periods are the time intervals between when interest is added to the account, and the more compounding periods, the better. The commonly used compounding schedule for savings accounts at banks is daily.

Daily compound interest formula

Daily compound interest is a modern way of calculating interest that is used for all financial and economic transactions worldwide. It is calculated on a regular interval, such as annually, semi-annually, quarterly, monthly, or daily. The more compounding periods, the better.

Daily compound interest is when interest on an investment or loan is calculated and added to the principal daily. This compounding increases the total return because each day’s interest calculation includes the interest from the previous days, leading to exponential growth of your investment.

The formula for daily compound interest is: A = P (1 + r / n)nt, where P is the principal amount, r is the annual interest rate, n is the number of compounding periods per year (365 for daily), and t is the time the money is invested, in years.

For example, if you invest £1000 in a savings account with an annual interest rate of 5%, and the interest is compounded daily, after one year you will have £1051.27. This is because each day’s interest calculation includes the interest from the previous days, leading to exponential growth of your investment.

Daily compound interest is a great option for short-term goals as it can slightly increase returns over short periods. It is also a good choice for tax-free savings accounts, such as ISAs, as the compounded interest grows without tax, maximising returns.

Savings accounts

For example, if you invest £1000 in a savings account with an annual interest rate of 5%, at the end of the year you will have £1050. However, if you invest the same amount in a savings account with daily compounding, you will earn interest not only on the initial £1000 but also on the interest accrued each day. This means that at the end of the year, you will have slightly more than £1050.

The interest rate on your savings account can vary depending on the financial institution and the type of account. For example, a high-interest savings account will typically offer a higher interest rate than a standard savings account. It's important to note that in a taxable savings account, the interest earned can be subject to tax, potentially slowing the growth of your compounded balance.

When choosing a savings account, consider the compounding frequency schedule. Daily compounding can slightly increase returns over short periods compared to longer compounding intervals. This is because the more compounding periods there are, the better. So, if you're looking to maximise growth in the short term, opt for a savings account with daily compounding.

Money market accounts

Compound interest can be calculated on a daily, monthly or annual basis. The more compounding periods, the better. The interest rate on your account can vary depending on the financial institution and the type of investment, such as a savings account, money market account, or a certificate of deposit (CD).

Certificates of deposit

Compound interest is a modern way of calculating interest that is used for all financial and economic transactions worldwide. It can be calculated on a daily, monthly or annual basis. The more compounding periods, the better.

The annual percentage yield (APY) is the number you should use when comparing CDs. The APY is a helpful number in comparing CDs of different term lengths because it always represents a CD’s annualised return. Two CDs offering the same interest rate and the same term may have different APYs if their frequencies of compounding interest and crediting the account are different—say, daily vs. monthly.

CDs are an attractive choice for low-risk, fixed-income investors looking for a reliable return on investment while taking advantage of compound interest. They can also be part of a diversified portfolio.

Tax-free accounts

There are several types of investments that compound interest daily, including high-interest savings accounts, money market accounts, and certificates of deposit (CDs). The interest rate on these accounts can vary depending on the financial institution.

One way to maximise the growth of your investment is to opt for a tax-free account, such as an Individual Savings Account (ISA). In a tax-free account, your compounded interest grows without tax, which can slow the growth of your balance. This means that each day's interest calculation includes the interest from the previous days, leading to exponential growth of your investment.

For example, let's say you invest £1000 in a tax-free account with a daily compound interest rate of 1%. After one year, your investment will have grown to £1036.89. This is because the interest is calculated daily and added to the principal amount, so you are earning interest on your interest.

Daily compound interest can be a powerful tool for growing your investments over time. However, it's important to note that the effects of compounding may be more noticeable over longer periods of time. Therefore, if you are investing for the long term, a tax-free account with daily compound interest could be a good option to consider.
