How to downgrade ChatGPT Pro to Plus on the web, iPhone or Android

Where do you downgrade ChatGPT Pro to Plus?

On chatgpt.com, the switch starts in Settings. OpenAI's Pro tiers article, read on 12 October 2026, gives one line for it: "Open Settings → My Plan to view your subscription and available plan changes." If Plus is on that list, pick it. If the panel only offers Cancel, the move takes two steps. You cancel Pro, then buy Plus once Pro has run out.

The label on the web isn't fixed. OpenAI's article says My Plan. On a Plus account we opened on 2 September 2026, the same entry read Billing, and its plan card had one control, Cancel plan, with no list of other tiers. So look for both names. OpenAI still has no help article on Pro to Plus, and its Go article is the only page that spells out what a step down does: "Your current plan will remain active until the end of your billing cycle."

As of October 2026, OpenAI sells Pro in three tiers: Pro 100 at $100 a month, Pro 200 at $200 and Pro 500 at $500. All three bill monthly. OpenAI's article says "Annual billing and payment for multiple months in advance are not available," so no Pro plan is ever more than a month from its renewal date.

When does the downgrade from Pro take effect?

A downgrade from Pro lands on your next renewal date, not the day you click. You keep Pro and its full allowance until the month you paid for ends. Plus then bills at $20, or $19.99 through the US App Store, per its listing on 12 October 2026.

Apple writes the rule down for every app it sells. A downgrade "continues until the next renewal date, then is renewed at the lower level and price." An upgrade works the other way: it's immediate, and Apple refunds the prorated part of the old plan. That's why there's no reason to wait. Schedule the move on day 2 of the cycle or day 29 and you'll pay the same. If you cancel instead, OpenAI asks you to do it at least 24 hours before the next billing date.

The usage window may not reset at the switch. In an OpenAI community thread, one subscriber reported that their Pro month ended on 16 August 2026 with the weekly Codex window already spent. They bought Plus at $20 on 17 August. The window had opened on 12 August, it didn't reset on purchase, and it stayed shut until 19 August. So in that one case, Plus began with no Codex capacity for about two and a half days.

Usage from the Pro period counted against the much smaller Plus limit, the same subscriber wrote, while regular chat kept working. It's the only finished Pro to Plus switch reported in the thread, and OpenAI hasn't documented the behavior. OpenAI Support answered there on 9 September 2026: "We haven't confirmed a fix or timeline." The fix you control is timing. If you lean on Codex, go easy on it in the last week of Pro so you don't carry a spent window onto Plus.

Do you get a refund when you downgrade from Pro to Plus?

No. OpenAI's Pro article says "Canceling your subscription does not automatically refund earlier charges," and the Go article answers its own refund question for Plus and Pro switchers with one word: "No." On the web and through Apple, the unused Pro days aren't credited toward Plus either. You just keep using Pro until they run out. Google Play says the developer decides how the rest of a plan is credited after a switch, and OpenAI hasn't published its rule.

Money comes back in narrow cases. OpenAI's refund article, read on 12 October 2026, starts from "Payments are generally non-refundable." An unused individual plan can get a discretionary refund if you contact OpenAI within seven days of the charge, through the chat widget at help.openai.com while signed in. The same article says an accidental purchase or "a plan change does not by itself qualify." It quotes 5 to 7 business days for a web refund and 10 for Google Play. Buyers in the EU, the UK and Turkey get a prorated refund if they cancel within 14 days of purchase. South Korea gets a full refund within 7 days if you haven't used the service. Apple handles its own refunds. Getting a refund on an AI subscription covers each biller.

What do you lose when you drop from Pro to Plus?

You lose the allowance and OpenAI's Pro models, and you keep your history. Chats, memory, custom instructions and projects stay on the account on every tier, which do you lose your chats when you cancel ChatGPT Plus covers in full.

Pro 200 subscribers have one less thing to weigh than they did in September. OpenAI let accounts active on Pro 200 between 22 and 29 September 2026 keep the old, larger allowance through 29 October 2026. On that date OpenAI canceled the cut and raised the lower allowance to match, so every Pro 200 plan has the larger one at the same $200. Dropping Pro 200 now doesn't forfeit a grandfathered allowance. The tier is open to new buyers again, too, after OpenAI paused Pro 200 sign ups on 10 September 2026. "New Pro 200 subscriptions are available from the pricing page," OpenAI says, so coming back later costs $200 and gets today's allowance.

If Plus feels too small, Pro 100 is the other step down, and OpenAI points every plan change to the same My Plan screen. TechCrunch reported at its 9 April 2026 launch that it carries 5x the Codex usage of Plus. ChatGPT Plus vs Pro covers who each tier fits.

How do you downgrade ChatGPT Pro on an iPhone or Android?

On an iPhone, Apple owns the plan, not OpenAI. Open Settings, tap your name, then Subscriptions, then ChatGPT, then See All Plans, and pick ChatGPT Plus. Apple's support page, published 14 September 2026, gives the same path, and Apple's renewal rule sets the timing. The US App Store lists Pro 100 at $100.00, Pro 200 at $200.00 and Pro 500 at $500.00, the web prices, so there's no store markup to escape. That's not true of Claude Max, which costs more through Apple.

Google Play is less tidy. Google's help page says a change between plans starts inside the app that sells it. It says you "may have to pay the full price or the price difference," and it leaves the credit for leftover days to the developer. OpenAI publishes no Android rule for Pro to Plus. The route that always works is to cancel in the Play Store under Subscriptions, ChatGPT, Cancel subscription, then buy Plus once Pro ends.

Deleting the app does nothing to the bill. OpenAI says so in both its cancellation article and its Pro article. How to cancel ChatGPT Plus has the full store paths, and how to downgrade ChatGPT Plus covers the next step down, to Go or free.

If Plus is too small and Pro costs too much

Most people leaving Pro want a strong model without a $100 to $500 bill, and Plus at $20 is the obvious landing spot. Whizi is another one. Its Pro plan is $29.99 a month, with Claude Opus, Claude Sonnet and ChatGPT Sol side by side, and credits per message vary by model and can change. It loses to ChatGPT Pro on volume, and Codex and agent mode stay OpenAI's. Whizi vs ChatGPT Plus lays the two out next to each other.
