To calculate the principal and interest payment for a loan, you can use the formula: Payment Principal x (Interest Rate / 12) / (1 - (1 Interest Rate / 12)(-Number of Payments)). This formula takes into account the loan amount (principal), the interest rate, and the number of payments.
the formula for simple interest is I=PRT (interest=principal x rate x time )
To find the total amount, you can use the formula: Total Amount = Principal + Interest. First, calculate the interest using the formula: Interest = Principal × Rate × Time (in months/12). Then, add the interest to the principal to get the total amount.
Simple interest is computed on the principal amount, which is the initial sum of money borrowed or invested. It is calculated using the formula: Interest = Principal × Rate × Time, where the rate is the annual interest rate and time is the duration in years. Unlike compound interest, simple interest does not take into account any interest that accumulates on previously earned interest. Thus, it remains constant throughout the investment or loan period.

I = prt where I = interest, p = principal, r = rate. and t = time in years.
I= Prt I=interest P=principal r=rate t=time
You need to know the principal amount, the rate and the time. Then a very simply formula for calculating interest is I = PRT where P is the principal amount, R is the interest rate and T is the period of time in years.
To calculate the simple interest earned on Susan's savings account, use the formula: Interest = Principal × Rate × Time. Here, the principal is $800, the rate is 6% (or 0.06), and the time is 5 years. Therefore, Interest = 800 × 0.06 × 5 = $240.00. The correct answer is C) 240.00.
Simple interest is a method of calculating the interest charged or earned on a principal amount over a specific period of time. It is computed using the formula ( I = P \times r \times t ), where ( I ) is the interest, ( P ) is the principal amount, ( r ) is the annual interest rate (as a decimal), and ( t ) is the time in years. Unlike compound interest, simple interest does not take into account any interest that has previously accrued on the principal. This makes it straightforward and easy to calculate for short-term loans or investments.
P*(1+R/100)powerT where P= money borrowed or principal and R= rate in percent and T= time * * * * * Actually, this formula gives the value of the principal PLUS interest. You need to subtract P from the answer to get the compounded interest.
Compound interest is calculated on the initial principal plus any accumulated interest, resulting in interest earning interest over time. Normal interest, on the other hand, is only calculated on the initial principal amount and does not take into account any interest that has already been earned.
