Renewal Uplift and FX Buffer Calculator

Use this calculator when a subscription will renew at a higher price, or when it is priced in US dollars and paid from Canadian-dollar revenue. It answers two questions: how much extra should I budget, and if my budget is fixed, how much contract value can I commit to today?

How to fill it in. Enter this year's subscription cost in Canadian dollars. In the percentage field, add the renewal uplift you have been told about (or the cap in your contract) to the exchange-rate buffer you want to hold for a USD contract. Put any fixed extras you already know about in the last field.

Formula. Increase to plan for = annual amount × percentage + fixed extras. Contract value absorbed today = annual amount − increase to plan for. The second figure is a conservative shortcut; the exact figure would divide by (1 + percentage), which gives a slightly higher number.

Worked example (illustrative). A $48,000 subscription faces a 7% renewal uplift, and the buyer holds a 5% buffer for USD moves: 12% in total. The increase to plan for is $48,000 × 12% + $2,400 = $8,160. If the budget must stay at $48,000, the business can only commit to about $39,840 of value at today's price and rate.

Limits. Exchange rates can move by more than any buffer, and the tool does not add GST/HST or QST. See the USD contracts and FX guide and the renewal uplift guide.
