1. Let Principal =P, Rate =R% per annum, Time =n years.
2. Rate compounded Annually :
Amount =P(1+R100)n
3. Rate compounded Half-yearly:
Amount =P[1+R/2100]2n
4. Rate compounded Quarterly:
Amount =P[1+R/4100]4n
5. Rate compounded Annually but time is in fraction, say 325 years.
Amount =P(1+R100)3 ×(1+25R100)
6. When Rates are different for different years, say R1%, R2%, R3 for 1st, 2nd and 3rd year respectively.
Then, Amount =P(1+R1100) (1+R2100) (1+R3100).
7. Present worth of Rs. x due n years hence is given by:
Present Worth =x(1+R100)
