No, when your subscription for some plan is still running, you will pay only the difference in the price for the selected higher plan. But when your current plan is Free or has expired, you will pay the price presented on the Pricing page. Upgrading your subscription does not extend the overall subscription period; the upgraded plan will last only for the duration of your original subscription timeframe.
