ToolSubscription cash-budget worksheet
What does that subscription really cost in cash?
Advertised monthly prices hide prepaid terms. Enter your own numbers in Canadian dollars and see what leaves your account today, what you will have paid within your planning horizon, and how many prepaid months would sit unused beyond it.
MethodHow the worksheet counts
The rules, in plain terms
- Blank means unknown, not zero. A blank field stops the calculation; type 0 if the cost really is nothing.
- Full cycles only. If the plan bills every 60 months and you plan 12 months ahead, you still hand over the full 60-month charge. The worksheet never prorates prepaid cash.
- A charge on the exact end of the horizon belongs to the next period and is not counted. Twelve months of a monthly plan is 12 charges, not 13.
- Cents are exact. Amounts are handled as whole cents so totals do not drift.
What it leaves out
- Sales tax, which varies by province and is added at checkout.
- Currency conversion if the merchant bills in another currency.
- Future price changes at renewal.
- Accessories, replacement parts, extra deliveries and cancellation fees.
- Any judgement about whether the purchase is worth it or affordable for you.
Two worked cases: item 100, upfront 10, 120 every 12 months, 24-month horizon → today 230, total 350, 0 unused months. Item 0, upfront 0, 300 every 60 months, 12-month horizon → today 300, total 300, 48 unused prepaid months.
