Compound Interest Calculator 📈

Vaddi mela Vaddi! (Interest on Interest)

Bank-la namba panam pota, adhuku vaddi tharuvanga. Compound Interest na enna? Mudhal varusham kedaikra vaddi-kum serthu adutha varusham vaddi kedaikum!

Indha project-la namba oru while loop use panni, ovvoru varushamum namba panam eppadi valarudhu nu paaka porom.

The Formula 🧮

Compound interest-ku oru direct mathematical formula irukku: A = P(1 + R/100)^t (A = Amount, P = Principal, R = Rate, t = Time)

Python-la idha epdi ezhudhalam na: amount = principal * (1 + rate/100) ** time.

Aana, loops eppadi work aagudhu nu practice panna, namba idha year-by-year oru while loop vechu calculate panna porom!

The Logic

• principal: Namba mudhalla podra panam (e.g. 10000).
• rate: Vaddi veedham (e.g. 5%).
• years: Evlo varushathuku panam podrom (e.g. 3).

Oru while loop vachi ovvoru varushamum vaddi calculate panni, principal kooda add pannanum.

principal = 10000
rate = 5
years = 3
current_year = 1

while current_year <= years:
    # 1 varushathuku vaddi: (Panam * Rate) / 100
    interest = (principal * rate) / 100
    principal = principal + interest
    print(f"Year {current_year}: Rs.{principal:.2f}")
    
    current_year += 1 # Adutha varushathuku porom!

Ippo indha loop eppadi step-by-step interest calculate pannudhu nu interactive-a paakalam!

Compound Interest Loop Tracker
principal = 10000
rate = 5
years = 3
current_year = 1

while current_year <= years:
interest = (principal * rate) / 100
principal = principal + interest
current_year += 1
Initial investment: Rs. 10,000. Start the loop to see interest grow year by year!
