# Subscriptions Upgrade

Thinking about taking your trading to the next level? Upgrading your Kingfisher subscription is designed to give you the maximum value possible.

Here is exactly how billing works when you decide to upgrade from a Premium plan to a Pro plan.

## How Your Upgrade is Calculated

Instead of complicated cost deductions or prorated refunds, we use a **Time Stacking** system that automatically upgrades your remaining time for free.

When you purchase an upgrade (for example, buying a Pro plan while still on Premium), you will be charged the standard price for the new plan you select. However, **you do not lose your existing plan.**

Instead, **all the remaining time on your current Premium plan is instantly upgraded to Pro**, and the new time you just purchased is added right on top.

### Example Scenario

Imagine you currently have **3 months of Premium left**, and you decide to buy **1 month of Pro**.

1. You pay the standard price for 1 month of Pro at checkout.
2. We take your remaining 3 months, add your newly purchased 1 month, and set your new expiry date to **4 months from now**.
3. Your entire account is instantly upgraded to **Pro**.

**The Result:** You receive 4 full months of Pro access. Your remaining 3 months of Premium were converted to the more expensive Pro tier at absolutely no extra cost to you!

## Frequently Asked Questions

<details>

<summary>Why was I charged the full amount at checkout?</summary>

When you upgrade, the checkout will always charge you the full amount for the specific block of time you are purchasing (e.g., 1 month or 3 months of Pro). Rather than discounting the price at checkout, we give you the discount in the form of free upgraded time applied to your remaining balance.

<summary>Can I upgrade if I have a lot of time left on my current plan?</summary>

Yes! Upgrading early is actually highly beneficial. The more time you have left on your Premium plan, the more time gets converted to Pro for free when you make your upgrade purchase.
