How the money is calculated
- Interest compounds once a year and is paid together with the deposit at the end of 5 years.
- The rate is fixed for the whole 5 years at the rate in force when you buy the certificate.
Maturity value = amount × (1 + rate)^5; interest for year y = balance at the start of year y × rate
A worked example you can check
