Fractional Portfolio Calculator NZ
This fractional portfolio calculator works out how many clients you need to reach a target income when you sell your time by the day to several organisations at once. A fractional executive, board adviser or part-time specialist rarely works for one client full time. Instead you build a portfolio: one client takes a day a week, another takes two, and the total has to add up to the income you want without filling more days than you are willing to work. The arithmetic is simple, but it is easy to get wrong in your head, because the weeks you actually bill are fewer than 52 and a part-filled week still needs a whole client to fill it. You enter your target income for the year, your day rate, the days a week each client takes, the weeks you expect to bill and the most days a week you want to work. The calculator gives you the number of clients needed, the client-days a week that takes, whether that fits within your maximum, and your income at full capacity, which is the most your day rate can earn on the days you are prepared to give. The day rate, the weeks and the maximum days are all your own choices, so change them to test a different portfolio.

Your day rate times the weeks you bill is what one day a week from one client earns you in a year. Dividing your target income by that gives the client-days you need each week. Dividing those client-days by the days each client takes, and rounding up to a whole client, gives the number of clients. The capacity check compares the client-days you need with the most days a week you are willing to work, and says so if the target cannot be reached without working more. Income at full capacity is your day rate times your maximum days a week times your weeks, the most this portfolio can earn at this rate. All figures exclude GST.
Worked example
A fractional chief operating officer wants $250,000 a year, charges $1,300 a day, sells each client one day a week and expects to bill 44 weeks. One client at one day a week earns $1,300 x 44, or $57,200 a year. The target divided by $57,200 is 4.37 client-days a week, so she needs 5 clients: four at a full day and a fifth who needs to supply only 0.37 of a day a week. That fits within her 4.5-day maximum, and at full capacity her rate would earn $257,400, only $7,400 above her target, so there is little room to add work at this rate.
| Step | Result |
|---|---|
| One day a week for 44 weeks at $1,300 | $57,200 |
| Client-days a week, $250,000 / $57,200 | 4.37 |
| Clients at one day a week each, rounded up | 5 |
| Capacity: 4.37 days against a 4.5-day maximum | Fits |
| Income at full capacity, $1,300 x 4.5 x 44 | $257,400 |
