Understand subscription cost escalation patterns

Subscription Prices Are Rising Faster Than Inflation

Major streaming and software subscriptions have raised prices 30–80% over the last three years — far outpacing general inflation. This calculator estimates how much more you're paying today versus when you first subscribed, and projects future costs.

The Creeping Cost Problem Most People Miss

Subscription price increases tend to arrive quietly — a small email notice, a modest bump of a pound or two. On its own, each rise feels manageable. But over several years, those increments stack up in ways that can genuinely surprise people. Many people find they are paying significantly more than they realised simply because they never stopped to add it all up. It can help to think of it as a slow leak rather than a sudden expense — easy to ignore, but worth considering when you are reviewing your monthly outgoings.

Why Projecting Future Costs Matters

One approach is to look ahead, not just backwards. If a service has increased its price at a consistent rate, that pattern may well continue. Projecting those costs forward — even as a rough illustration — can give a clearer picture of what you might expect to spend over the next few years. That kind of visibility is often what prompts people to reassess whether a subscription still represents fair value for them.

Run it with sensible defaults

Using original monthly price of 10, current monthly price of 18, years subscribed of 4, years to project of 5, the calculation works out to 37.53. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Original Monthly Price, Current Monthly Price, Years Subscribed, and Years to Project — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

How the math works

This calculator determines the annual inflation rate of the subscription by comparing original and current prices over time, then projects future costs assuming that rate continues unchanged. It uses compound growth mathematics. Results are illustrative estimates based on historical pricing patterns and do not account for promotional rates, plan changes, or market fluctuations. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Revisiting the plan

Budgets are living documents. Re-run this whenever income changes, housing changes, or you notice a recurring overrun in a category. A budget from two years ago is probably already wrong.

What this doesn't capture

Budgets are snapshots of intent. Real spending includes irregular costs: birthdays, one-off repairs, the occasional bad week. Tracking actual spending for a month before fixing any budget usually reveals 10–20% that didn't make the original plan.
