----------------------------------------------------------------
After some conversation with [~uddyangoyal] we agreed on the below:
*Parameters*
A = Maturity Amount
P = Principal amount
r = Rate of Interest (in decimals)
n = number of compounding in a year (yearly = 1, quarterly = 4, monthly = 12)
t = number of years
*Formula*
A = P (1+r/n) ^ (n * t)
*Example*
For example, if a sum of 10,000 is invested for 3 years at 10% compound
interest rate (quarterly compounding), then at the time of maturity,
A= 10,000 \{1 + (0.1/4)} ^ (4 * 3)
A = 10,000 (1 + 0.025) ^ (12)
A = 10,000 (1.025) ^ (12) = 13,449 (approximately)
[~ruhiu] [~bgowda] Please let us know if you see some problem with the above
strategy!

> *As a* user
> *I want system* to calculate the interest of the Fixed deposit account before
> the account creation
> *in order to* give flexibility to the customers to know their liability
> before account creation
> h4. *Background and details:*
> Need to add a new capability to calculate *interest for fixed deposit
> savings* based on the interest posting period and interest compounding period
> before the creation of the fixed deposit saving.
> This enhancement will empower the customers to have a comprehensive preview
> of the interest that will be accrued at the maturity of their fixed deposit
> savings, enabling them to make informed decisions.
> To achieve this,an API endpoint is required that can perform the interest
> calculation for fixed deposit savings. The API endpoint should accept
> parameters such as the {*}principal amount, interest rate, tenure, interest
> posting period, and interest compounding period{*}. Upon receiving these
> inputs through a POST request, the endpoint should conduct the necessary
> calculations and return the maturity amount and interest earned in the
> response.
> UI button “{*}calculate Interest{*}” should be available on create fixed
> deposit account view screen for users to know the interest after entering all
> the parameteres
>
> Ex API:
> *POST* /api/calculate-fixed-deposit-interest
> *Request Body:*
> {
> "principal_amount": 10000, // The initial amount deposited
> "interest_rate": 5, // Annual interest rate (in percentage)
> "tenure": 12, // Number of months for which the FD is held
> "interest_posting_period": 3, // Posting period of interest (in months)
> "interest_compounding_period": 1 // Compounding period of interest (in
> months)
> }{*}Response Body:{*}
> {
> "maturity_amount": 10512.5, // Total amount at maturity (including interest)
> "interest_earned": 512.5 // Interest earned during the tenure
> }
> *Acceptance criteria*
> # I want to be able to calculate the interest on Fixed deposit during
> account creation phase
> # a button should be available on the UI for users to calculate and show the
> interest based on the parameters entered ({*}principal amount, interest rate,
> tenure, interest posting period, and interest compounding period{*})
