We show these calculations because full transparency matters to us. Once a plan is created, the annual interest rate sticks till maturity; it doesn't change.
This annual interest rate is computed daily and added to your plan daily based on your saving balance.
For a duration of less than a year, the per annum (annual) interest rate is prorated over the said period and broken down to daily returns so you can monitor it on your app.
For example, if a plan commands 5% interest per annum, this rate will be prorated to give you a daily return of 5% / 12 multiplied by your principal over the duration of the plan.
