Does it support growing annuities and perpetuities?

Absolutely. It includes the Gordon Growth Model and growing annuity formulas, which are essential for equity valuation and long-term financial projections.

Can it generate a full mortgage amortization table?

Yes, it can calculate periodic payments and provide a detailed breakdown of interest paid, principal reduced, and remaining balance for each period of a loan.

How does it calculate Internal Rate of Return (IRR)?

Since IRR lacks a closed-form solution for general cash flows, the skill utilizes numerical methods to solve for the discount rate that sets the Net Present Value to zero.

Can this skill handle continuous compounding?

Yes, the skill includes formulas for continuous compounding using the exponential constant, alongside discrete frequencies like monthly, quarterly, or annual compounding.
