Template for 40-year quarterly cash flow mixed with some monthly flows
I deal with long-term (up to forty year) quarterly cash flows.
Generally, there will be certain items that will increase at an assumed rate of inflation, while other items will have an additional adjustment such as inflation plus 1%. Mostly, I will want to show four equal payments in any one financial year and apply an annual inflation uplift. This I can manage. However, I also need to integrate cost schedules that may have payments occuring in periods that do not tally with my quarterly schedule. Typically, these will arrive from an external source. So I have a few fixed dates and payments in one sheet and I would like to interleave these with my quarterly dates and payments. e.g. Sheet1 - external cost schedule DateX DateX + 1 month DateX + 3 months DateX + 4 months DateX + 5 months DateX + 5 months and 3 days (maybe I don't need this level of precision but let's generalise) Sheet2 - cash flow [Earlier of DateX or Start Date of quarterly flows - if equal, that's OK, use one of them] [Earlier of (next unused date in DateX series or next unused date in quarterly flows)] etc. I then need to ensure that any payments or uplifts that are due to occur, say, only once every four quarters, will be correctly applied only at the relevant dates. Ideally, I also need to be able to deal with items such as tax payments that are calculated in relation to a range of dates with an offset from the date that they fall due. Finally, I need to ensure that, once set up, any model is readily maintainable by intelligent non-programmers (after it has been carefully explained to them). So do I need to just use VBA to build my cash flow sheet or can I do clever things with dynamic ranges? Can I build an array of quarterly dates from within an Excel function or UDF? Can I take two arrays of dates and produce one array of unique, sorted dates from within an Excel function or UDF? Any hints/tips/solutions gratefully received. |
