What is the time cost of a purchase?

The time cost of a purchase converts the price of something into the number of work hours required to afford it. Calculated as: Work Hours = Purchase Price ÷ True Hourly Rate. This reframes spending decisions in terms of irreplaceable life time — not just money.

How is the true hourly rate different from my nominal salary?

Your true hourly rate accounts for auxiliary costs of working — commuting time, travel expenses, work clothing, meals, and taxes. After subtracting these from take-home pay and dividing by total hours spent on work (including commute), your effective hourly rate is significantly lower than your gross pay rate suggests.

What is opportunity cost in personal finance?

Opportunity cost is the potential return you give up by choosing one option over another. For spending decisions, the opportunity cost is the future value that money could have grown to if invested instead. For example, ₹10,000 spent today forgoes approximately ₹31,058 in 10 years at 12% annual return.

How can the time cost calculator help me reduce unnecessary spending?

By converting a price into work hours, impulse purchases feel more tangible. When you realise a ₹5,000 gadget costs 8 hours of your working life — and its opportunity cost is over ₹15,000 in 10 years — the decision becomes clearer. It is a practical mindfulness tool for intentional spending.
