Can I afford to hire? A framework for the biggest decision you will make

Hiring is one of the most powerful things a small business can do, and one of the easiest to get badly wrong. The mistake is almost never the person — it is the timing, and it usually traces back to deciding on the strength of one good month rather than a durable trend. Here is a framework that takes the emotion out of it.

The true cost is far more than the salary

A salary is only the visible part of the cost. On top of it sit employer National Insurance, the minimum pension contribution required under auto-enrolment, equipment, software licences, recruitment fees, and the weeks or months before a new person is fully productive. As a working rule of thumb, budget around 1.3 times the headline salary for the real monthly cost. A 36,000 pound salary is closer to a 47,000 pound annual commitment, or roughly 3,900 pounds a month.

Test it against runway, not last month

The wrong question is whether you can afford the hire this month. The right question is what happens to your runway if you carry this cost for the next twelve months. Add the all-in monthly cost to your current burn, recalculate your runway, and look at the new number. If hiring takes you from twelve months of runway to five, that is a very different decision from one that takes you from twelve to ten.

Build in a margin for being wrong

Revenue rarely arrives exactly when or in the amount you expect. Before committing, stress-test the decision: what does your runway look like if revenue is fifteen percent lower than planned for a quarter? If the answer still leaves a comfortable buffer, you can hire with genuine confidence. If it does not, you have learned something important before signing a contract rather than after.

“

Hire from a position of trend, not a position of hope. One strong month is not a hiring signal. Three months of growing net cash flow is.

The payback question

A good hire eventually pays for themselves — either by generating revenue or by freeing you to. Before hiring, write down, honestly, how this role earns or saves its cost, and roughly how long that should take. A salesperson might pay back in months; a support hire might pay back by letting you take on more clients without dropping the ball. If you cannot describe the payback, the timing is probably not right yet.

Cheaper ways to test the need

If the need is real but not yet clearly permanent, you do not have to jump straight to a full-time, permanent contract. A contractor, a part-time arrangement, or a fixed-term hire lets you test whether the work is durable before taking on a long-term fixed cost. Many of the best permanent hires start this way.

Fincharta lets you model exactly this — add a cost, adjust revenue, and watch what happens to your runway before you commit a single pound. See the scenario planner.
