房贷计算器是一个简单的Python程序,通常用于帮助用户计算按揭贷款的月供、总利息等信息。以下是一个基本的房贷计算器脚本示例:
```python
# 定义函数计算每月还款额
def mortgage_calculator(principal, interest_rate, loan_term, down_payment):
# 计算贷款本金
remaining_principal = principal - down_payment
# 转换利率为小数形式
interest_rate_monthly = interest_rate / 100 / 12
# 利息和本金相加得到每月应还金额
monthly_interest = remaining_principal * interest_rate_monthly
monthly_repayment = (monthly_interest + remaining_principal) / 12
return monthly_repayment
# 输入贷款相关信息
principal = float(input("请输入贷款总额(元):"))
interest_rate = float(input("请输入年利率(%):"))
loan_term_years = int(input("请输入贷款年限(年):"))
down_payment = float(input("请输入首付比例(%),如20表示20%:"))
# 将贷款年限转换为月数
loan_term_months = loan_term_years * 12
# 计算首付
down_payment_amount = principal * (down_payment / 100)
# 计算月供
monthly_payment = mortgage_calculator(principal, interest_rate, loan_term_months, down_payment_amount)
print(f"每月应还款额为:{monthly_payment:.2f}元")
