«Планы возврата денег» относятся к финансовым продуктам или инвестиционным схемам, которые предлагают гарантированный возврат инвестированной суммы в течение определенного периода. Вот несколько методов и примеров кода, связанных с планами возврата денег:

1. Фиксированный депозит с ежемесячной процентной ставкой:
   Пример кода:

   principal_amount = 100000  # Initial investment amount
   interest_rate = 5.0  # Annual interest rate
   investment_period = 5  # Investment period in years
   total_interest = (principal_amount * interest_rate * investment_period) / 100
   monthly_interest = total_interest / (investment_period * 12)
   maturity_amount = principal_amount + total_interest
   print("Maturity Amount:", maturity_amount)

2. Регулярный депозит с единовременным возвратом:
   Пример кода:

   monthly_deposit = 5000  # Monthly deposit amount
   interest_rate = 6.0  # Annual interest rate
   investment_period = 3  # Investment period in years
   maturity_amount = (monthly_deposit * investment_period * ((investment_period + 1) / 2) * interest_rate / 100) + (monthly_deposit * investment_period)
   
   print("Maturity Amount:", maturity_amount)

3. Полис страхования жизни с возвратом денег:
   Пример кода:

   premium_amount = 5000  # Monthly premium amount
   policy_term = 20  # Policy term in years
   maturity_amount = premium_amount * policy_term * 12
   print("Maturity Amount:", maturity_amount)

4. Взаимный фонд с возможностью выплаты дивидендов:
   Пример кода:

   investment_amount = 100000  # Initial investment amount
   annual_growth_rate = 8.0  # Expected annual growth rate
   dividend_percentage = 2.0  # Dividend payout percentage
   total_growth = (investment_amount * annual_growth_rate * investment_period) / 100
   dividend_amount = (total_growth * dividend_percentage) / 100
   maturity_amount = investment_amount + total_growth + dividend_amount
   print("Maturity Amount:", maturity_amount)

5. План поддержки:
   Пример кода:

   premium_amount = 10000  # Annual premium amount
   policy_term = 15  # Policy term in years
   sum_assured = 200000  # Assured amount
   maturity_amount = premium_amount * policy_term + sum_assured
   print("Maturity Amount:", maturity_amount)
