How does a loan calculator factor your interest? Great question, the formula loan calculators use is **I = P * r *T** in layman's terms Interest equals the principal amount multiplied by your interest rate times the amount in years.

If you want to do the monthly mortgage payment calculation by hand, you'll need the monthly interest rate — just **divide the annual interest rate by 12 (the number of months in a year)**. For example, if the annual interest rate is 4%, the monthly interest rate would be 0.33% (0.04/12 = 0.0033).

- a: $100,000, the amount of the loan.
- r: 0.005 (6% annual rate—expressed as 0.06—divided by 12 monthly payments per year)
- n: 360 (12 monthly payments per year times 30 years)

The rate of interest (R) on your loan is calculated monthly i.e. (**R= Annual rate of interest/12/100**). For instance, if R = 15.5% per annum, then R= 15.5/12/100 = 0.0129.

How much interest will you pay? The simple interest formula is: **Interest = Principal x rate x time** 4. Interest = $100 x .

Formulas for Interests (Simple and Compound) SI Formula. **S.I. = Principal × Rate × Time**. CI Formula. C.I. = Principal (1 + Rate)^{Time} − Principal.

We can calculate an original loan amount by **using the Present Value Function (PV) if we know the interest rate, periodic payment, and the given loan term**. This function tells the present value of an investment.

**Explanation**

...

- 0.0125.
- The cell containing the interest rate divided by 12.
- 15%/12.

- Convert the annual rate from a percent to a decimal by dividing by 100: 10/100 = 0.10.
- Now divide that number by 12 to get the monthly interest rate in decimal form: 0.10/12 = 0.0083.

- rate - The interest rate per period. We divide the value in C5 by 12 since 4.5% represents annual interest:
- nper - the number of periods comes from cell C7, 60 monthly periods in a 5 year loan.
- pmt - The payment made each period. This is the known amount $93.22, which comes from cell C6.

**=PMT(17%/12,2*12,5400)**

The rate argument is the interest rate per period for the loan. For example, in this formula the 17% annual interest rate is divided by 12, the number of months in a year. The NPER argument of 2*12 is the total number of payment periods for the loan.

The interest rate is **the amount a lender charges a borrower and is a percentage of the principal—the amount loaned**. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).

Firstly, multiply the principal P, interest in percentage R and tenure T in years. For yearly interest, **divide the result of P*R*T by 100**. To get the monthly interest, divide the Simple Interest by 12 for 1 year, 24 months for 2 years and so on.

**Money (or property) given with the promise that it will be paid back in the future, usually with interest**. In this example Alex borrows $1,000, and has to pay back $1,100 next year.

Common examples include **home purchase loans, auto loans, personal loans, and many student loans**. Revolving loans allow you to borrow and repay repeatedly.

A loan is **an arrangement under which a lender allows another party the use of funds in exchange for an interest payment and the return of the funds at the end of the lending arrangement**. Loans provide liquidity to businesses and individuals, and as such are a necessary part of the financial system.

**E = P x r x ( 1 + r ) ^{n} / ( ( 1 + r )^{n} - 1 )** where E is EMI, P is Principal Loan Amount, r is monthly rate of interest (For eg. If rate of interest is 14% per annum, then r = 14/12/100=0.011667), n is loan duration in number of months.

An **equated monthly instalment** (EMI) is a set monthly payment provided by a borrower to a creditor on a set day, each month. EMIs apply to both interest and principal each month, and the loan is paid off in full over some years.

With a loan amount of $30,000, an interest rate of 8%, and a loan repayment period of 60-months, your monthly payment is **around $700**.

**=PMT(rate, nper, pv, [fv], [type])** The PMT function uses the following arguments: Rate (required argument) – The interest rate of the loan. Nper (required argument) – Total number of payments for the loan taken.

To calculate your monthly car loan payment by hand, **divide the total loan and interest amount by the loan term** (the number of months you have to repay the loan). For example, the total interest on a $30,000, 60-month loan at 4% would be $3,150.

Your monthly payments would look like this for a $40,000 loan: **36 months: $1,146**. **48 months: $885**. **60 months: $737**.

The monthly payment on a $50,000 loan ranges from **$683 to $5,023**, depending on the APR and how long the loan lasts. For example, if you take out a $50,000 loan for one year with an APR of 36%, your monthly payment will be $5,023.

A good personal loan interest rate depends on your credit score: **740 and above: Below 8% (look for loans for excellent credit)** **670 to 739: Around 14% (look for loans for good credit)** **580 to 669: Around 18% (look for loans for fair credit)**
