## Any Payment Required, Revisited

I want to revisit the post I wrote earlier in the month called “Payment Required to Earn “X” IRR”. The reason I want to revisit it is because when I said any cash flow can be changed, I meant any . I think this spreadsheet calculator can come in handy in a number of ways. Lets say your firm is […]

## MSR (Mortgage Servicing Rights) VBA Function

I have tried to stay away from VBA calculations for my Excel spreadsheets, principally because my programming does not have the polished look of a good programmer. Programming in VBA for me was self taught, and based on the “Basic” programming language I learned in the 70’s. Enough excuses. Download Excel spreadsheet :”MSR“ There are times when […]

## Relationships – XIRR(), Amortization, Present & Future Value

The first thing to discuss is the difference between APR (Annual Percentage Rate) and APY […]

## Payment Required to Earn “X” IRR

That seemed to me to be a useful calculator […]

## Present and Future Value Proofs

Back in Oct. 2014, I posted a spreadsheet that calculated the present and future values of a cash flow with even periods and uneven cash flows. I thought I might expand on that spreadsheet by adding a few ways to proof the answers you get using the calculator. These are the formulas used for the […]
