I haven't really seen solvers in other packages that are general in the sense that the return type can change depending on what parts of an equation are missing. It...

so far I'm only able to calculate this for the very special cases of simple interest/discount, and compound rates however, for more general cases, we'd need calculus since \delta_t =...

currently only accepts a discount function, although it works if payments already have discount factors provided but, if payments do not have discount factors attached, then we should be able...

Payments can accept a list of payments, but it should accept more sources, such as: 1. pandas DataFrame 2. SQL 3. delimited text files (csv, tsv, etc.)

You should be able to: 1. Insert payments 2. Remove payments 3. Modify payments a. modify payment time b. modify payment discount c. modify payment amount

Tiered investments are now possible, but the code is quite messy, it may be possible to simplify it.

Although an npv function exists to calculate net present value, it would be nice to have a solver that can solve for missing amounts. For example, if a payment happens...

Not all accumulation functions have K explicitly defined. It would be nice to have k as an optional argument, and when it is not given, the value for k should...
