Using the Forecast for Hiring or Investment Decisions
How to model a new hire or capital investment against your projected cash position using the AskBiz Rolling Cash Forecast and Cost Configuration tools.
Key Takeaways
- You can model a new hire's total cost by adding their salary and employer costs to your Fixed Costs configuration and watching the forecast update immediately.
- The forecast shows exactly how many weeks of runway the additional cost removes, giving you a data-driven hiring timeline.
- Combining the forecast with the Cash Runway card gives a complete picture of whether the business can sustain the investment over the next six to twelve months.
Why the Forecast Is the Right Tool for Hiring Decisions
Hiring someone is one of the largest ongoing cost commitments you will make as a business owner. A new full-time employee does not just cost their monthly salary — it also includes employer taxes, equipment, onboarding time, and often reduced productivity during the first one to three months. The Rolling Cash Forecast lets you stress-test the decision before signing an offer letter. By adding the total cost to your configuration, you can see exactly how the hire affects your projected net cash week by week and whether your cash balance can sustain it without a shortfall.
Step 1 — Calculate the True Monthly Cost of the Hire
Before modelling in AskBiz, work out the total monthly cost. Start with the gross salary. Add employer national insurance or payroll tax (typically 10 to 15 percent depending on your jurisdiction). Add any benefits such as pension contributions, health cover, or equipment. Include a rough onboarding allowance for the first month. For example, a hire with a $3,500 monthly salary might cost $4,200 all-in once taxes and benefits are added. This is the number you will enter into AskBiz.

Open the Intelligence tab and navigate to Cash Flow. Click the Cost Configuration button (usually a gear or settings icon near the top right of the CFO section). In the Fixed Costs panel, click Add Cost. Name it something clear such as New Hire — Sales Associate. Enter the monthly amount. Set the start date to the proposed hire date. Save the configuration. AskBiz will immediately recalculate your Projected Outflows for all future weeks from that start date onward.
Step 3 — Read the Forecast Impact
With the new cost added, return to the Rolling Cash Forecast table. Compare the Net Cash row and running balance to what they showed before. Notice two things: first, the weekly Net Cash figures will be lower from the hire date forward; second, the running balance will decline faster. Now look at the Cash Runway card — it will have recalculated to show the new runway with the hire included. If the original runway was 14 months and the hire reduces it to 10 months, you now have a concrete number to weigh against the expected revenue the hire will generate.
Step 4 — Stress Test With the Ask AI Button
Once you have modelled the hire, click Ask AI on the Cash Runway card. AskBiz AI will analyse the new configuration and give you a plain-language assessment: Can your current trajectory support this hire? What revenue increase would the hire need to generate within 90 days to remain cash-positive? Are there lower-priority costs you could reduce to offset the hire? This gives you a balanced, data-informed view rather than a purely intuitive one. If the numbers are close, you can also model a part-time hire first by entering 50 percent of the full cost and checking whether the forecast remains healthy.
