The employer is checking whether you can communicate technical output to clients or managers who are not finance specialists, a daily analyst responsibility.
Start with a plain definition, use a simple investment example, connect both metrics to a decision rule, and check for understanding.
Start by anchoring the explanation in something the client already understands, like a savings account or a loan. Say plainly that money today is worth more than the same amount next year because you could invest it now, so a peso received in three years is not the same as a peso in hand today. Then introduce NPV as the answer to one question: after accounting for that timing, does this project bring in more than it costs? Walk through a small example, say a PHP 100,000 investment that returns PHP 30,000 a year for four years, and show that you subtract the upfront cost from the total of those future values, each discounted back to today. If the result is positive, the project earns more than the cost of waiting, so you say yes. Then explain IRR as the interest rate at which that NPV becomes zero, meaning the project exactly breaks even on a time-adjusted basis. Frame the decision rule simply: if the IRR is higher than the company's required return, the project is worth doing. Keep your tone conversational and Taglish if the client speaks that way, but avoid jargon entirely. Pause after each step and ask, "Does that make sense so far?" to keep them engaged and confirm they are following before you move on.
A common mistake is to say 'Actually sir, ang NPV po is yung future cash flow na idi-discount po natin' and then drop heavy formulas. Instead, say 'NPV tells us whether the project earns more than it costs, adjusted for timing.'
Situation
In my student investment club, I was assigned to explain a project proposal to members from non-business courses.
Task
I had to translate NPV and IRR into everyday language so the group could decide whether the club should fund a campus event.
Action
I compared NPV to checking whether the event would make back more than what we put in, after accounting for the timing of ticket sales and costs. I said a positive NPV means the event adds value, while a negative one means we would be better off not doing it. For IRR, I explained it as the break-even rate of return, and that we should accept the project if IRR is higher than our next best alternative. I avoided formulas and used a simple payback example.
Result
The non-business members asked focused questions about timing and risk, and the club approved the project with a clear rationale. My co-lead later asked me to write a one-page plain-English guide.
Use relatable comparisons and avoid finance jargon when explaining metrics to non-specialists.
