Introduction

Subscription creep is what happens when you sign up for things one at a time, each for a reasonable monthly amount, and never add them up. The gym you joined in January. The streaming service you added for one show. The software trial that converted to a paid plan without you quite noticing. The newspaper you meant to cancel after the introductory offer.

Individually, none of them feel significant. Together, they are often one of the largest discretionary outgoings in a household budget – and unlike groceries or fuel, they require no active decision to continue. They leave the account every month regardless of whether you used them.

This calculator makes the total visible. Tick the ones you pay for, adjust any amounts that differ from the defaults, and add anything that is not on the list. The result is your monthly subscription total, your annual cost, and what that same monthly amount would produce if invested in a stocks and shares ISA instead – at 6% annual return over your chosen timeframe.

How to use this calculator

Tick the subscriptions you currently pay for. The presets cover the most common UK subscriptions – streaming, music, fitness, news, software and household services. The default amounts are approximate current prices; edit any figure that differs from what you actually pay.

Check the frequency. Most subscriptions are monthly, but some (antivirus software, annual streaming bundles, some news subscriptions) are billed annually. The calculator converts all frequencies to a monthly equivalent for comparison.

Add anything not on the list. Use the custom subscription field at the bottom to add anything from a meal kit delivery to a children’s educational app to a specialist magazine. Name it, enter the amount, select the billing frequency and click Add.

Adjust the projection period. The slider below the ISA investment figure runs from 1 to 30 years. Slide it to your chosen timeframe to see the compound investment equivalent. The longer the period, the more dramatic the contrast between “what I spend” and “what it could have been.”

Use the bar chart. The biggest subscriptions by monthly cost are shown as a ranked bar chart below the totals. This makes it immediately clear which subscriptions are driving the overall figure – and therefore which cancellations would have the most impact.

Frequently asked questions

What is subscription creep?

Subscription creep is the gradual accumulation of recurring subscriptions over time – each added individually for a small monthly fee, rarely reviewed collectively, and tending to expand rather than contract. The psychological mechanism is straightforward: signing up to a new service requires an active decision, while cancelling requires a separate active decision. When the default state is “continue paying”, inertia keeps subscriptions running even when they are rarely used.

The average UK household now spends significantly more on subscriptions than most people estimate. Research consistently finds that people underestimate their monthly subscription total by 50 to 100% when asked before seeing the actual figure.

How does the investment calculation work?

The calculator uses a standard compound interest formula for regular monthly contributions. It assumes the full monthly subscription total is invested at the start of each month into a stocks and shares ISA, earning 6% annually, over the number of years shown on the slider.

6% is used as the assumed annual return – a conservative figure for a globally diversified equity index fund, below the historical long-run average of approximately 7 to 8% but realistic for planning purposes. The calculation is illustrative rather than a guaranteed projection – investment returns are variable and the actual outcome would differ depending on when contributions were made and how markets performed.

The purpose is not to suggest that cancelling subscriptions and investing the money is automatically the right decision – for subscriptions you genuinely use and value, the calculation is irrelevant. It is to make visible the opportunity cost of subscriptions that are barely used or that you had forgotten you were paying for.

Should I cancel all my subscriptions?

No – and this calculator is not an argument for doing so. Subscriptions you use regularly and value are a legitimate use of money. The question is whether each subscription is providing value commensurate with its cost, and whether you are making an active choice to keep each one or simply not getting around to cancelling it.

The useful exercise is the audit rather than the cancellation. Go through each ticked subscription and ask two questions: did I use this in the last month? And if I did not have it, would I sign up for it today at this price? If the answer to both is no, cancellation is straightforward. If the answer to either is yes, keep it.

How do I cancel subscriptions I no longer want?

Most UK subscriptions can be cancelled through the provider’s website or app – typically under account settings or subscription management. A few tips worth knowing:

Check the billing date before cancelling. Most subscriptions continue until the end of the current billing period rather than refunding pro-rata. Cancelling the day after a renewal means you have paid for a full month you will not use.

Annual subscriptions may be refundable. Some providers offer a partial refund on annual subscriptions cancelled mid-term. Check the terms – it is worth asking even if not stated explicitly.

Free trials that convert automatically. If you signed up for a trial and it converted to a paid subscription without a clear reminder, you can usually cancel and request a refund for the first payment if caught quickly. Your bank can also raise a dispute for charges you did not authorise.

Virtual cards for trials. Using a virtual card number (available through Revolut, Curve, and some banks) for free trials prevents automatic conversion to paid subscriptions – the card details stop working when you close the virtual card.

Why do streaming services keep increasing their prices?

The streaming market has moved from a growth phase – where platforms competed on price to gain subscribers – to a profitability phase, where the same platforms are raising prices and reducing content quality to improve margins. Netflix, Disney+ and others have all raised prices significantly in the last two years and introduced advertising-supported tiers to increase revenue per user.

The result is that the combined cost of maintaining multiple streaming services now rivals or exceeds a traditional TV package. This is worth reviewing periodically – the individual prices look modest; the stack does not.

What is the best way to reduce my subscription total?

Rotate rather than stack. Watch everything you want on one service, cancel, subscribe to the next, repeat. This requires slightly more active management but reduces the monthly total significantly for light-to-moderate viewers.

Share plans where permitted. Most streaming services offer family or household plans at a modest premium over individual plans. Netflix’s household sharing policy has tightened, but other services still permit legitimate household sharing.

Use free alternatives. BBC iPlayer, Channel 4 streaming, ITV X, and Pluto TV are free with a TV licence or entirely free. They cover a significant proportion of what most people watch on paid services.

Review annually. The most effective time to audit subscriptions is at the start of January (New Year motivation) and early April (before the ISA year end, when the opportunity cost of unnecessary spending is most visible). Set a calendar reminder.

Check what you are actually using. Most banks and apps now categorise direct debits and show subscription payments clearly. Review the last three months of outgoings, identify every subscription payment, and cross-reference against this calculator’s list.

Can I see which subscriptions cost me the most?

Yes – the bar chart in the results panel shows your active subscriptions ranked by monthly cost, with the largest at the top. This makes it immediately visible where the money is going. A gym membership at £40 per month shows as roughly four times the bar length of a streaming service at £10 – which can reframe the decision about which cancellation makes most sense.

What is included in the Amazon Prime entry?

The calculator includes two Amazon entries: Amazon Prime Video as a standalone streaming service, and Amazon Prime (full) covering the full Prime membership. The full Prime membership includes delivery, Prime Video, Prime Music, Prime Reading, and other benefits – the relevant comparison is whether you use enough of the additional benefits to justify the premium over the streaming-only equivalent. If you primarily use Amazon Prime for delivery and free video is incidental, the full membership price is the appropriate figure.

Does the calculator save my selections?

No – the calculator does not store any data. Your selections exist only for the duration of your browser session. If you close the page or refresh it, the ticks and any custom subscriptions you added will be cleared. This is intentional – no data about your subscriptions is sent anywhere or retained.

If you want to keep a record of your current subscription total, copy the monthly and annual figures before leaving the page.
