# Changing Subscription Plans

When changing the plan of a subscription, by default we prorate the charge for the next billing cycle.

Suppose you purchase a subscription plan for $50 on April 1st; you’ll be charged immediately. If you decide to upgrade to a  $100 plan on April 15th, you’ll see a charge of $125 on May 1st. This includes $100 for the new plan, $50 for the time used on the upgraded plan from April 15th to May 1st, and a $25 credit for the time you didn’t use on the previous plan.

<table><thead><tr><th width="444">Charge</th><th>Amount</th><th>Next Invoice</th></tr></thead><tbody><tr><td>Renew Charge</td><td>$100</td><td>$100</td></tr><tr><td>Upgrade plan partially used time</td><td>$50</td><td>$150</td></tr><tr><td>Unused time on previous (old) plan</td><td>-$25</td><td>$125</td></tr></tbody></table>

If downgrading a subscription, we’ll issue a credit which is then applied on the next invoice.
