How Subscription Cost Is Calculated

Özet

A subscription cost calculator adds up all your recurring charges — streaming services, music, gaming, gym memberships, software, and more — and shows the total on a monthly, annual, and daily basis. The average Brit spends around £65 per month (£786/year) on subscriptions, and a third say they’re overspending.

Nasıl çalışır

The calculation is simple arithmetic, but the value comes from seeing all subscriptions together. Individual charges of £10–15/month feel small; the aggregate often surprises people.

The calculator handles three billing periods:

1. Monthly — the most common. Annual cost = monthly × 12.
2. Annual — services like Amazon Prime. Monthly equivalent = annual ÷ 12.
3. Weekly — some newspapers and niche services. Annual cost = weekly × 52.

All costs are normalised to monthly and annual totals for easy comparison.

Formül

Where the annualised cost depends on billing period:

And the derived totals:

• Monthly total = sum of each subscription’s monthly equivalent
• Daily total = annual total ÷ 365
• Coffee equivalence = monthly total ÷ average coffee price (£3.50)

UK subscription pricing (early 2026)

These are the standard individual-tier prices for common UK subscriptions:

Prices change frequently — check your bank statement for your actual costs.

• Subscription list — toggle on the services you pay for from the preset list, or add custom subscriptions with a name, cost, and billing period.
• Cost — editable per-subscription. Adjust to match your actual plan (e.g., family vs. individual tier).
• Billing period — monthly, annual, or weekly. Determines how the cost is annualised.

Çıktılar açıklaması

• Annual cost — the headline number: what you spend per year on all active subscriptions combined.
• Monthly cost — the sum of all monthly equivalents, useful for budgeting.
• Daily cost — annual ÷ 365, which makes the cost feel tangible.
• Coffees per month — your monthly subscription spend expressed as cups of coffee (at £3.50 each), for perspective.
• Bar chart — visual comparison of each subscription’s annual cost.
• Breakdown table — per-subscription monthly and annual costs.
• 5-year / 10-year projection — simple multiplication to show long-term impact.

Varsayımlar ve sınırlamalar

• Prices are defaults, not guarantees. Subscription prices change frequently (Netflix, Spotify, and Disney+ all raised UK prices in 2025). The calculator uses representative UK prices as starting points — users should adjust to their actual costs.
• No price inflation modelling. The 5/10-year projections assume constant prices. In reality, subscription costs have been rising 5–10% annually.
• No usage-based value assessment. The calculator shows cost, not value. A £13/month Netflix subscription used daily is better value than a £7/month service used once.
• Tax is included. UK subscription prices are quoted inclusive of VAT, so no tax adjustment is needed.
• Currency is GBP only.
