Formula:

Total Amount = Principal + CI (Compound Interest)
a. Formula for Interest Compounded Annually Total Amount = P(1+(R/100))n
b. Formula for Interest Compounded Half Yearly Total Amount = P(1+(R/200))2n
c. Formulae for Interest Compounded Quarterly Total Amount = P(1 + (R/400))4n
d. Formulae for Interest Compounded Annually with fractional years (e.g 2.5 years) Total Amount = P(1 + (R/100))ax(1+(bR/100)) here if year is 2.5 then a =2 and b=0.5
e. With different interest rates for different years Say x% for year 1, y% for year2, z% for year3 Total Amount = P(1+ (x/100)) x (1+(y/100)) x (1+(z/100)) Where, CI = Compound Interest P = Principal or Sum of amount R = % Rate per annum n = Time Span in years

For compounding interest calculation, select an option (annually or half-yearly or quarterly) from the drop-down menu of 'Interest Compounded' box and enter the inputs, the compound interest calculator will update you the CI with ease. Compounding interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. It is also referred as 'interest on interest'. Higher the number of compounding periods, higher is the CI. Apart from CI, this compound interest calculator helps you to calculate principal and rate of interest too.

Example

If a person deposit Rs. 5000 paying 6% interest for 5years.What will be the compound interest on the same sum at the same rate for the same period, compounded annually?

Compound Interest= P(1+(R/100))^n
=5000(1+(6/100))^5
=Rs. 1691.13
Total Amount = Principal + Compound Interest
=Rs. 6691.13
