How to calculate Treasury bills in Nigeria

Remember that the Federal government issues Treasury bills at discounted prices and upon maturity, the government repurchases them at a full quotation. For example, if an investor buys a N300, 000 Treasury bill at a discounted rate of N200, 000 for 364 days. After the purchase, the Federal government writes an IOU (I owe you) of the initial amount, N300, 000 and pledges to pay after 364 days.

Upon expiration of the set tenure, the government buys back at the full price- N300, 000. The interest rates for these bonds are not fixed. The Central Bank of Nigeria and the demand for the Treasury bills determine the stop rate.

You can calculate your return on investment upon investing in Treasury bills. This is the amount you should expect at maturity. Here is how to calculate your returns.

If you buy a 364-day Treasury bill worth N300, 000 at your bank or from a stockbroker at an interest rate of 10%.

You can calculate the upfront payment using the formulae below.

Interest = Principal × Time × Rate/100

Principal = N300, 000 Time = 364 days (equivalent to 1 year) Rate = 10% all over 100

N300,000 × 1 × 10/100 = N30,000 This, therefore, means that you will get paid N30,000 at the start of your investment and the remaining N270,000 is remitted to the Central Bank of Nigeria. The figures above should tell you that your investment is N270,000 and not N300,000 because you get N30,000 back.

How then do you determine your actual rate of return?

Rate = (Interest × 100)/ (Principal x Time) (30000 × 100) ÷ (270000 × 1) = 11.1%

This is how you to determine your interest rates on Treasury bills in Nigeria.

Investing in Treasury bills in Nigeria is easy and profitable. However, if you wish to invest in this sector, you must familiarize yourself with the business first before you venture into it.
