Rounding shortcuts that turn Canadian dollar prices into rupees in your head, with the error percentage of each rule.
This cheat sheet turns a rupees-per-dollar exchange rate into arithmetic you can do standing at a till in Canada. It splits the rate into a decimal shift and a working multiplier between 1 and 10, then searches three families of shortcut — a whole-or-half multiplier, that multiplier plus an easy percentage nudge like 10%, 25% or 5%, and the nearest simple fraction — and reports the fixed percentage error of each, because a pure multiplier is off by the same percentage whatever the price. It is for Indian travellers, students and new arrivals in Canada who want a rule they can trust to within about 2% without unlocking a phone.

Every shortcut is labelled with the percentage it overshoots or undershoots the exact conversion.
Only whole and half multipliers, decimal shifts, and percentage nudges people can do without paper.
It also derives the rupees-to-dollars rule, so a ₹10,000 budget becomes a dollar figure in one step.
Round the rate to a whole number and multiply. At roughly ₹62 per dollar the quick rule is to multiply by 60, which lands about 3% low, then add 2.5% — around ₹1.50 in every ₹60 — if you want to close most of that gap. Enter the day's rate above and the sheet picks the closest easy rule for it.
About 2% is enough for everyday shopping. On a C$25 restaurant main a 2% error is roughly ₹30, which will not change your decision; on a C$2,000 flight it is about ₹2,500, so check big purchases on a phone or a bank statement instead.
The rate you see quoted is the mid-market rate. Indian cards typically add a foreign-currency markup of around 2% to 3.5% plus GST on that fee, and an ATM abroad adds its own withdrawal charge, so the rupee figure on your statement is normally a few per cent above the mental estimate. Treat this sheet as a shopping estimate, not a settlement figure.
No. Both were replaced by coins — the $1 loonie in 1987 and the $2 toonie in 1996 — so the smallest note you will be handed is C$5 and the largest in general circulation is C$100. The one-cent coin was also withdrawn in 2013, which is why cash totals are rounded to the nearest five cents while card totals are not.
