How do you find the principal when all you have is the rate the time and the interest?
The answer depends on whether you are dealing with simple interest of compound interest.
Suppose P = Principle
R = Rate (in % per annum)
T = Time (in years)
I = Interest
Then for simple interest:
I = P*R*T/100 so that P = 100*I/(R*T)
For compound interest
P+I = P*(1+R/100)T
so that P = I/[(1+R/100)T - 1]

How do you solve interest rate math problems?
First you figure out the Principal, then you find the interest rate and then find the Time someone gave you to pay back loaned or borrowed money.Formula: Simple Interest= Principal*Rate*TimeExample: Principal-$25,000 Interest Rate- 6.25 simple interest- 6 years$25,000 x .0625 x 6= $9375!
If a simple interest of 4.5 percent was paid at the end of the year then find the balance at the end of the year?
The formula for simple interest is Interest = Principal x Rate x Time ÷ 100 As the rate is an annual rate and the period is 1 year then Interest = Principal x 4.5/100. The balance at the year end = Principal + Interest = Principal x 104.5/100.
How do you find total amount if principle rater of interest months and interest is given?
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.
Find the ordinary interest on 1800 for two months at the rate of 12 percent?
To calculate the ordinary interest, use the formula: Interest = Principal × Rate × Time. Here, the principal is $1800, the rate is 12% (or 0.12), and the time is 2 months (which is 2/12 years). Thus, the interest is: Interest = $1800 × 0.12 × (2/12) = $36. So, the ordinary interest on $1800 for two months at a 12% rate is $36.
What is an amount of money multiplied by the interest rate and the amount of time that the money will be earning interest?
The amount of money multiplied by the interest rate and the amount of time it earns interest represents the interest earned over that period. This can be expressed using the formula: Interest = Principal × Rate × Time, where the Principal is the initial amount of money, Rate is the interest rate (as a decimal), and Time is the duration in years. This calculation is fundamental for understanding simple interest in finance.
How do you do interest rate problems?
First you figure out the Principal, then you find the interest rate and then find the Time someone gave you to pay back loaned or borrowed money.Formula: Simple Interest= Principal*Rate*TimeExample: Principal-$25,000 Interest Rate- 6.25 simple interest- 6 years$25,000 x .0625 x 6= $9375!
How can I find the interest payment on a loan or investment?
To find the interest payment on a loan or investment, you can use the formula: Interest Principal x Rate x Time. The principal is the amount of money borrowed or invested, the rate is the interest rate, and the time is the duration of the loan or investment. Plug in these values to calculate the interest payment.

Find the formula of simple interest?
the formula for simple interest is I=PRT (interest=principal x rate x time )
If a simple interest of 4.5 percent was paid at the end of the year then find the balance at the end of the year?
The formula for simple interest is Interest = Principal x Rate x Time ÷ 100 As the rate is an annual rate and the period is 1 year then Interest = Principal x 4.5/100. The balance at the year end = Principal + Interest = Principal x 104.5/100.
Where can find the simple mathematical formula for calculating interest?
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.
How do you find the time for principal and rate?
If you are working on simple interest you have to write the equation I=p. r.t
How do you calculate the interest on a T-bill investment?
To calculate the interest on a T-bill investment, you can use the formula: Interest Principal x Rate x Time. The principal is the amount you invest in the T-bill, the rate is the interest rate of the T-bill, and the time is the length of time you hold the T-bill. Multiply these three values together to find the interest earned on your investment.
Which of these is the correct formula for calculating interest on a loan?
interest = prinsciabl x rate x time
Find the ordinary interest on 1800 for two months at the rate of 12 percent?
To calculate the ordinary interest, use the formula: Interest = Principal × Rate × Time. Here, the principal is $1800, the rate is 12% (or 0.12), and the time is 2 months (which is 2/12 years). Thus, the interest is: Interest = $1800 × 0.12 × (2/12) = $36. So, the ordinary interest on $1800 for two months at a 12% rate is $36.
Formula for calculating compound interest?
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.
How is the amount of interest earned on an investment calculated?
The amount of interest earned on an investment is calculated by multiplying the principal amount invested by the interest rate and the time the money is invested for. This formula is typically expressed as: Interest Principal x Rate x Time.
