Normalise every plan to an effective monthly price, then divide it two ways. \(\text{Effective Monthly} = \frac{\text{Annual Price}}{12}\) where annual billing exists, otherwise the monthly rate. From there, \(\text{Cost per TB} = \frac{\text{Effective Monthly}}{\text{Capacity GB}} \times 1000\) ranks providers against each other, and \(\text{Cost per GB stored} = \frac{\text{Effective Monthly}}{\text{Storage You Need}}\) tells you what you are paying for the data you actually have. Published comparisons give you the first number and stop. It quietly assumes you will fill the plan, which almost nobody does — and the gap is large. On a 2 TB plan at $9.99/month holding 300 GB, cost per TB reads a tidy **$5.00**, while the honest per-GB figure is **$0.0333** — about six and a half times the headline rate of $0.005 per GB. At the mainstream 2 TB tier, illustrative 2026 pricing compares like this: • **iCloud+ 2 TB**, $9.99/month, no annual option — **$9.99** effective, **$4.995/TB**, **$599.40** over five years • **Google One 2 TB**, $9.99/month or $99.99/year — **$8.33** effective, **$4.166/TB**, **$499.95** over five years, saving **$19.89/year** • **Dropbox Plus 2 TB**, $11.99/month or $119.88/year — **$9.99** effective, **$4.995/TB**, **$599.40** over five years, saving **$24.00/year** Annual billing is doing most of the work in that table. Google One and Dropbox charge different monthly rates but land within a cent of each other once you compare like for like — and switching Dropbox from monthly to annual saves more per year than the entire price gap between the two providers. ## How to Use This Calculator: A 300 GB Library Across Three Providers Enter what you actually store first. Check your current provider's usage screen rather than estimating — this figure drives the only metric that reflects your real cost. This example uses 300 GB against the three 2 TB plans above. Google One comes out cheapest to fit: $99.99 ÷ 12 = **$8.33/month effective**, **$99.99/year**, **$499.95 over five years**. iCloud+ and Dropbox Plus both land at **$9.99/month effective** and **$599.40 over five years** — Dropbox only matches iCloud because its annual price cancels out its higher monthly rate. Now the reality check. All three plans are **15% utilised**, leaving **1,700 GB** spare. Cost per GB you actually store is **$0.0278** on Google One and **$0.0333** on the other two — six to eight times the per-capacity rate that provider marketing quotes. That is not automatically a reason to switch. The tier below 2 TB is usually 100 GB or 200 GB, which a 300 GB library does not fit, so buying capacity you will not use may simply be the cheapest option available. The point is to know that is the trade you are making, and to revisit it when providers add intermediate tiers. ## A Second Example: When a Cheap Plan Is the Expensive One Scale the library to **1,800 GB** and the ranking inverts entirely. Against a 50 GB plan at $0.99/month, a 100 GB plan at $19.99/year, and a 2 TB plan at $99.99/year: The 50 GB plan is **$0.99/month** and the 100 GB plan **$1.67/month effective** — both far cheaper than the 2 TB plan's **$8.33/month**. Both are also **useless**, holding 3% and 6% of the library respectively, and the calculator marks them as too small rather than letting them win a comparison they cannot actually enter. Their cost per TB tells the same story from the other direction: **$19.80/TB** for the 50 GB plan and **$16.66/TB** for the 100 GB plan, against **$4.17/TB** for the 2 TB plan. Small tiers are dramatically worse value per unit — the 50 GB plan costs nearly five times as much per terabyte as the 2 TB plan. At 1,800 GB the 2 TB plan is **90% utilised**, cost per GB stored falls to **$0.00463**, and the headline and honest metrics finally converge. That convergence is the signal you have bought the right tier. ## Annual Billing, Utilisation, and the Costs Comparisons Leave Out Three structural things decide a cloud storage bill, and only one of them is the price on the page. **Billing period** is worth 10–20% on most providers, and it is the single easiest saving available — but it is also the reason monthly headline prices cannot be compared directly, which is why this calculator normalises everything to an effective monthly figure first. **Utilisation** decides whether the price is good value for you specifically. Tier sizes jump in large steps — 50 GB, 200 GB, 2 TB — so most people sit well below their ceiling for most of a plan's life. That is tolerable; paying for a 2 TB plan to store 40 GB is not, and the cost-per-GB-stored figure is there to make the difference visible. **Duration** is what turns a small monthly difference into a real number. A $1.67/month gap looks trivial and comes to **$100 over five years** — and cloud storage is the subscription people cancel least, because cancelling means moving or deleting data. Which brings up the cost this comparison genuinely cannot see: leaving. Consumer providers rarely charge egress fees, but the time cost of re-uploading a terabyte over a domestic connection is real, and on business or object-storage tiers there is a literal bill — the [cloud egress cost calculator](/calculators/cloud-egress-cost-calculator) prices that side. Before any of it, get the library size right with the [data storage calculator](/calculators/data-storage-calculator), and for current consumer plan pricing and a fuller sizing walkthrough see the [cloud storage planning guide](/blog/tech/cloud-storage-planning-guide). ## Limitations This calculator performs exact arithmetic on the capacities and prices you enter, and its accuracy depends entirely on those matching current published pricing. The default plan values are illustrative figures reflecting commonly cited 2026 consumer pricing, not a live feed — providers restructure tiers, change prices, and run promotional first-year rates that quietly revert, so check each provider's own page before deciding. It compares price and capacity only, which is deliberately not the whole picture. It cannot weigh bundled value (a plan including an office suite, a VPN, or family sharing is not competing on storage alone), file versioning depth, end-to-end encryption, upload and sync speed, platform integration, business features, or the reliability record that actually determines whether your data survives. A plan that wins on cost per TB and loses on every one of those is not the better plan. It also does not model growth. Entering today's library against today's tiers tells you nothing about the year your photo collection crosses a tier boundary and the bill doubles overnight — and because tiers jump in large steps, that is exactly how cloud storage costs behave. Run the comparison again with your expected library in two or three years and see whether the ranking survives it. ## Related Calculators Size the library before pricing it: the [Data Storage Calculator](/calculators/data-storage-calculator) turns photo, video, and document counts into the GB figure this comparison needs, and the [Video File Size Calculator](/calculators/video-file-size-calculator) covers the video files that usually dominate a personal storage total. For moving data between providers or storing it on infrastructure rather than a consumer plan, the [Cloud Egress Cost Calculator](/calculators/cloud-egress-cost-calculator) prices transfer out and the [VPS & Server Cost Calculator](/calculators/vps-server-cost-calculator) prices self-hosted storage.

Convert every plan to an effective monthly price first — annual price divided by 12, or the monthly rate where there is no annual option — then compare cost per TB. Comparing advertised monthly prices directly is misleading, because providers with a higher monthly rate often have a cheaper annual one. ### What is a good price per TB for cloud storage? At the mainstream 2 TB consumer tier, published 2026 pricing puts the value leaders near $4.17 per TB per month on annual billing, with most major providers around $5.00 and bundled-software plans higher. Small tiers are far worse value: a 50 GB plan at $0.99/month works out to $19.80 per TB, nearly five times the 2 TB rate. ### Why does cost per GB matter more than cost per TB? Cost per TB assumes you fill the plan. If you store 300 GB on a 2 TB plan you are 15% utilised, so the price you pay for the data you actually have is $0.0333 per GB against a headline rate of $0.005 — about six and a half times higher. Cost per TB ranks providers; cost per GB stored tells you whether the tier is right for you. ### Is annual billing worth it for cloud storage? Usually yes — it saves roughly 10–20% on most providers, and it is the easiest saving available on this kind of subscription. On the illustrative 2 TB plans above it is worth $19.89 a year on Google One and $24.00 on Dropbox Plus, in both cases more than the price difference between the two providers. ### How much cloud storage do I actually need? Check your current provider's usage screen rather than estimating — most people overestimate substantially. If you are starting from scratch, count your photo, video, and document library with a storage calculator, then add room for two or three years of growth, since tier sizes jump in large steps and crossing a boundary can double the bill. ### Should I buy a bigger plan than I need? Often you have no choice, because tiers jump from around 200 GB straight to 2 TB — a 300 GB library has to buy 2 TB. That is fine as long as you know it is happening. What is not fine is sitting at 2% utilisation on a large plan for years because you never revisited it after a one-off transfer. ### Does this calculator include the cost of switching providers? No. Consumer providers rarely charge egress fees, but re-uploading a large library over a domestic connection costs real time, and business or object-storage tiers do charge for data transfer out. Price that side separately with an egress cost calculator before assuming a cheaper plan is a cheaper move. ### Why is the five-year total the number to look at? Because cloud storage is the subscription people cancel least — cancelling means moving or deleting data, so plans persist for years. A $1.67/month difference that looks trivial is $100 over five years, and that is the horizon on which the decision is actually made. ## Related concepts - **Effective Monthly Price** — Annual price divided by 12, or the monthly rate where no annual option exists. The only basis on which plans with different billing periods can be compared. - **Cost per TB vs Cost per GB Stored** — The first ranks providers against each other assuming a full plan; the second divides the same price by your real library. They diverge sharply at low utilisation. - **Tier Boundary** — The point where a library outgrows a plan and jumps to the next size. Because consumer tiers step in large increments, crossing one can double a bill overnight. ## Related guides - [How Much Cloud Storage Do You Actually Need?](https://dothecalculation.com/blog/tech/cloud-storage-planning-guide) — Why video dominates storage far more than photo count suggests, and how to compare Google One, iCloud+, and Dropbox pricing honestly using official 2026 rates. - [How to Use Do The Calculation Calculators: A Practical Step-by-Step Guide](https://dothecalculation.com/blog/site-guides/how-to-use-calculators) — Learn the fastest reliable workflow for using Do The Calculation calculators, reading results, checking formulas, and using save, print, share, and export actions correctly. ## Related calculators - [Cloud Storage & Egress Cost Calculator](https://dothecalculation.com/calculators/cloud-egress-cost-calculator) — Compare bandwidth transfer and data egress costs across AWS, Google Cloud, Azure, and Cloudflare R2 storage providers instantly. - [Data Storage Calculator (GB/TB/photos/videos)](https://dothecalculation.com/calculators/data-storage-calculator) — Calculate total storage needed for photos, videos and documents in GB and TB, plus an estimated monthly cloud storage cost. - [Website Hosting Cost Comparison Calculator](https://dothecalculation.com/calculators/website-hosting-cost-calculator) — Break a hosting bill into base fee, bandwidth overage, and storage overage to see what's driving your monthly cost. - [AI Tokens & Cost Calculator](https://dothecalculation.com/calculators/ai-tokens-calculator) — Estimate tokens, simulate prompt caching savings, compare API costs across leading LLM models, and calculate multi-turn chat context growth. - [CI/CD Minutes Cost Calculator](https://dothecalculation.com/calculators/cicd-minutes-cost-calculator) — Price GitHub Actions minutes with per-job rounding, OS multipliers, and the included allowance on your plan. - [Serverless Compute & Cost Estimator](https://dothecalculation.com/calculators/serverless-cost-calculator) — Estimate monthly cloud function costs, billable GB-seconds, and evaluate cold start latency overhead for serverless applications. --- _This calculator performs exact arithmetic on the capacities and prices you enter.
