🛠️ Simple Math Calculation (Flat Rate Installment)

For simple installment plans or flat-rate monthly loans, you can calculate the monthly payment using basic arithmetic addition, division, and multiplication.

Step-by-Step Simple Math Formulas:

Monthly Principal Payment: Divide the total loan amount by the total number of months:
```
= Loan_Amount / Total_Months
```
Monthly Interest Amount: Multiply the loan amount by the monthly interest rate:
```
= Loan_Amount * Monthly_Interest_Rate
```
Total Monthly Payment Formula: Add monthly principal and monthly interest together:
```
= (Loan_Amount / Total_Months) + (Loan_Amount * Monthly_Interest_Rate)
```

Example Scenario:
- Loan Amount: $1,000 (Cell B1)
- Duration: 10 months (Cell B2)
- Monthly Interest Rate: 1.5% or 0.015 (Cell B3)
- Monthly Principal: = B1 / B2 ($1,000 / 10 = $100)
- Monthly Interest: = B1 * B3 ($1,000 * 1.5% = $15)
- Total Monthly Payment: = (B1 / B2) + (B1 * B3) -> $115 per month
