Which grows more?
Eight quick rounds. Two real options, one right answer, and the arithmetic shown every time.
Most financial mistakes are not made by people who cannot do the maths. They are made by people who never ran it, because the wrong answer felt obviously right. A 15-year loan at a slightly higher rate against a 25-year loan at a lower one. ₹5,000 a month for twenty years against ₹15,000 a month for eight. A 7% deposit against a fund yielding 9% with a 1.5% expense ratio.
Each round puts two of those side by side and asks which ends up ahead. Then it shows the working — the formula, the figures, and where the intuition went wrong. The point is not the score. It is that after a dozen rounds you start estimating these correctly in your head, which is the skill the calculators were only ever confirming.
No sign-up, no scores kept unless you want them, and every question is drawn from the same formulas the calculators use.
The questions are deliberately built so that the obvious signal is the wrong one. A higher rate paired with a shorter run. A larger monthly amount paired with a later start. A better headline return paired with a fee that quietly removes most of it. Each round isolates one of those pairings, so a wrong answer tells you which variable you are systematically under-weighting rather than just that you guessed badly.
The kinds of question it asks
- Time against rate — a longer run at a lower return against a shorter one at a higher return
- Amount against start date — a larger contribution begun later against a smaller one begun now
- Gross return against cost — a higher-yielding fund against a cheaper one, where the expense ratio decides it
- Tenure against instalment — the loan that is comfortable each month against the one that is cheaper in total
