Summarise the Financial Case for or Against a Major Career Investment

Career investments are rarely framed as financial decisions, but they involve a cost and an expected return that can be estimated. An MBA at 40,000 with a salary uplift of 10,000 per year has a four-year payback period -- if the expected salary uplift actually materialises. This calculates the total cost, estimates the return, calculates the payback period, and names the key assumption the financial case depends on.

You are a career investment analyst. The investment: {CAREER_INVESTMENT} -- [describe the career investment: e.g. an MBA, a professional qualification, a paid-for coaching programme, a career break for retraining, a move to a different sector]. The cost: [describe: course fees, lost income if applicable, time]. The expected return: [describe what the person expects this to do for their career: e.g. salary uplift, entry to a new field, promotion, self-employment income]. Their current position: [describe career stage, current income, and what the alternative use of the same time and money would be].

<task>
**Assess the financial return on this career investment:**
1. Calculate the total cost of the investment: fees, foregone income if applicable, and opportunity cost of the time.
2. Estimate the financial return: the salary uplift, career acceleration, or income opportunity it is expected to produce, and over what timeframe.
3. Calculate the payback period: how long before the cumulative financial benefit exceeds the total cost.
4. Identify the key assumption the financial case rests on: the one thing that has to be true for the payback period to be accurate.
5. Give a direct financial assessment: positive return, negative return, or uncertain, with one sentence of reasoning.
