Case studies
Four decisions taken apart with the same calculators you can open right now — situation, what was calculated, the actual numbers, and the outcome.
Rent vs buy in Bengaluru
Paying ₹42,000 a month in rent while a ₹1.1 crore apartment tempts. Modelling the EMI, stamp duty and the opportunity cost of the down payment changes the answer.
US mortgage refinance
A $420,000 mortgage at 7.1% with 27 years left, and a 5.9% refinance offer carrying $9,400 in closing costs. The break-even month decides it.
NRI retirement corpus
AED 32,000 a month, zero income tax, and a plan to retire in Hyderabad at 55. Inflation in INR — not the AED salary — sets the target.
GST & cash flow
₹68 lakh of annual billings at 18% GST. The business was profitable on paper and short of cash every quarter — the timing of GST payments explained why.
