If You Swap Existing SSB (SBOCT21) with New SSB (SBFEB26)
Profit/Loss
The Profit/Loss chart depicts the difference in interest on a month-to-month basis, while the Cumulative Profit/Loss chart depicts the cumulative difference as time goes forward.
To use the charts, first, define your intended holding period, that is, how long you intend to hold the SSB. Is the money needed in 2-3 years, or it is spare money that you can invest for the long term? Then, check the Cumulative Profit/Loss chart to see if it shows meaningful positive values during the intended holding period.
Summary
| If You Swap and Hold SBFEB26 Until | Cumulative Profit/Loss |
|---|---|
| Jan 2027 | -$12.39 |
| Jan 2028 | -$18.49 |
| Jan 2029 | -$20.60 |
| Jan 2030 | -$17.71 |

| Sep 2031 | -$25.89 |
Swapping an SSB requires that you have spare money to apply for the new SSB, as the proceeds from early redemption of existing SSB will only be received early next month. Furthermore, if you apply for a large amount (especially if more than $10,000) on a popular SSB, you may not receive the full allotment. Check recent allotment results ("Quantity Ceiling") to get a sense of the amount you may be allotted.

The SSBs do not pay monthly interest! However, in order to compare the interest of 2 SSBs, it is necessary for us to compare on a month-to-month basis. This is because the 2 SSBs may pay interest in different months. For example, one SSB pays in Jan and Jul, and the other pays in Feb and Aug. Having monthly interest allows us to compare 2 SSBs objectively.
The monthly interest is calculated based on the difference in accrued interest assuming early redemption. For example, accrued interest for 2 months minus accrued interest for 1 month, and we get the interest for the second month.
Despite our best effort to provide accurate interest calculations, we noted some minor differences (eg. $6.78 vs $6.81) under rare situations between our calculated interest and what is presented in the official SSB Calculator. These sometimes occur for specific SSBs with issue date that did not fall on the first calendar day of the month, and it affects the interest for the first 5 months. The SSB technical specification does not indicate how weekends and public holidays are treated in accrued interest calculations. There may be other differences that we are unaware of. Nonetheless, the differences are small enough and rare enough that they do not change the fundamental trend/shape of the charts. The 6-monthly scheduled interests are accurate as far as we know. Anyway, if you need to know the exact interest payouts (scheduled interest or early redemption), please use the official SSB Calculator.
