This application can calculate different discrete compounding interest factors, continuous compounding interest factors and continuous compounding continuous flow factors. Discrete compounding interest factors: Single sum, present worth factor (P|F i%,n). Single sum, compound amount factor (F|P i%,n). Uniform series, present worth factor (P|A i%,n). Uniform series, capital recovery factor (A|P i%,n). Uniform series, compound amount factor (F|A i%,n). Uniform series, sinking fund factor (A|F i%,n). Gradient series, present worth factor (P|G i%,n). Gradient series, uniform series factor (A|G i%,n). Gradient series, compound amount factor (F|G i%,n). Geometric series, present worth factor (P|A1 i%,j%,n). Geometric series, future worth factor (F|A1 i%,j%,n).
