Free Website Bandwidth & Data Transfer Estimator for Indian Websites
This estimator turns daily pageviews and average page size into monthly data transfer in GB and a peak Mbps figure with a 2.5× headroom multiplier for your viral day. A CDN slider removes the share served from the edge. Shared plans from ₹299 a month carry generous transfer; high-traffic sites should verify the allowance against this number.
For site owners sizing a hosting plan before the overage mail arrives: estimate the monthly GB, compare the allowance, keep headroom.

Bandwidth estimator
Enter your numbers below — the maths is shown beside every result so you can audit it. Everything runs in your browser; nothing is sent anywhere.
Estimate monthly transfer
Monthly GB = pageviews × page size × 30 ÷ 1024 × (1 − CDN%). Peak Mbps = monthly GB ÷ 30 ÷ 86400 × 1024 × 8 × 2.5 × (1 − CDN%) — a sustained-rate figure with 2.5× headroom for your viral day. Runs entirely in your browser; nothing is sent anywhere.
How the monthly bandwidth estimate is calculated
The estimate multiplies daily pageviews by average page size to get daily transfer, scales it by 30 days for the monthly figure, and converts a per-second share of that traffic into Mbps with a 2.5× headroom multiplier. Every step is arithmetic you can check by hand.
| Step | Formula | Why it is there |
|---|---|---|
| Daily transfer | pageviews × page size ÷ 1024 | Base traffic per day, converted from MB to GB |
| Monthly GB | daily × 30 | The number a hosting allowance is measured against |
| Peak Mbps | pageviews ÷ 86,400 × page size × 8 × 2.5 × (1 − CDN%) | Sustained bit rate with 2.5× headroom for the viral day |
| Cache discount | multiply by (1 − CDN%) | CDN hits are served from the edge and never touch your origin |
A worked example with the default inputs: 10,000 pageviews a day at a 2 MB average page with no CDN gives 19.5 GB a day and about 585.9 GB a month. The per-second rate is 10,000 ÷ 86,400 ≈ 0.116 views a second, which at 2 MB is roughly 1.85 Mbps sustained; the 2.5× multiplier lifts the figure to about 4.63 Mbps. Move the CDN slider to 60% and the origin only carries 40% of that — 234.4 GB a month at 0.74 Mbps sustained before headroom.
The divisor 1024 (not 1000) is used throughout, so the figures are gibibytes — the same unit hosting control panels report as GB. If your traffic report uses decimal GB, expect the panel number to read a few percent lower than the tool's.
What the result means for the hosting plan you need
The monthly GB figure answers "does the plan's transfer allowance fit my site", and the peak Mbps figure answers "is the connection fast enough at my busiest second" — two different questions, both worth checking. An allowance can be ample in total and still choke if the rate spikes past what the port serves comfortably.
- Monthly GB vs allowance: compare against the transfer allowance published for the plan. Shared hosting from ₹299 a month carries generous transfer for typical small sites; when the estimate runs into hundreds of GB, VPS from ₹499 a month or cloud hosting tiers carry more.
- Peak Mbps vs port: a 4–5 Mbps sustained-with-headroom figure is easy pipe; hundreds of Mbps suggest a dedicated line or a CDN in front of the origin.
- The 2.5× headroom: it exists because real traffic is not spread evenly across 86,400 seconds — Indian waking hours compress the day's views into a fraction of it, and the viral day compresses it further.
Every WebJi® plan behind these estimates carries the same floor: a 99.9% monthly uptime target, 24/7 Hindi and English support with average first replies under 60 minutes, and INR billing with 18% GST shown separately on the invoice. The plain-English version of the transfer concept is in the what is bandwidth guide.
Limits of this estimator — what it does not model
The estimator models page-view traffic only; it deliberately excludes email, backups, FTP uploads, database replication and streaming media, any of which can exceed a site's page traffic on a hosting plan. Read it as an indicative figure for the web-serving line of your bandwidth, not a binding allowance.
- Uniform-distribution assumption: the Mbps figure spreads views evenly across the day before applying headroom; diurnal peaks are sharper than even 2.5× in some niches.
- Page size is your number: the tool trusts the average you enter. Measure it as the weighted average of your top pages — most Indian sites land between 1 MB and 3 MB per view — and note that compression (gzip/Brotli) is already inside a measured page size, not applied on top.
- CDN is a flat percentage: the slider models a uniform cache-hit share. Real hit rates differ by asset type; static-heavy sites see a larger cut after moving assets to a CDN, as the what is a CDN guide explains.
- 30-day month: the monthly figure uses 30 days; a 31-day month adds about 3%.
- Excluded entirely: mail flow, nightly off-site backups, large file downloads and video served from origin — budget those separately in GB per month.
Rerun the tool whenever traffic changes materially — after a redesign that changes page weight, a campaign, or a CDN move — and keep the result row for the plan comparison.
From the estimate to the right hosting tier
Take the monthly GB and peak Mbps figures to the plan comparison, then let the desk match the binding allowance before you order. The pricing page publishes the current card, and the tools hub carries the matching estimators — the cloud server cost calculator prices the compute side once bandwidth has picked the tier family.
- Run the estimator with your measured pageviews and page size, CDN at its real share.
- Compare the GB figure against the published allowance of the tier you were considering; move up a family if the fit is tighter than about 30% headroom.
- Send the numbers in — open the contact page or email support@webji.services with traffic, page size and the estimate; the desk replies with the recommended tier, the deliverables list and the INR quote.
Frequently asked questions
Does cached traffic count towards my bandwidth?
CDN-served hits do not touch your origin bandwidth — that is what the CDN slider models. Static-heavy sites often see a large cut in origin transfer after moving assets to a CDN, sometimes more than the slider's conservative 90% ceiling suggests for image catalogues.
What if my page size varies a lot between pages?
Use the weighted average of your top pages: weight each page's size by its share of views, so a heavy gallery page that few people open does not distort the figure. Most Indian sites land between 1 MB and 3 MB per view; text-first blogs sit below 1 MB.
Are these GB figures binary or decimal?
Binary: the tool divides by 1024, so its GB are gibibytes — the same unit hosting control panels report. Traffic reports that use decimal GB (÷1000) will read a few percent lower for the same traffic, which is a rounding difference, not an error.
Does the estimate include email, backups or file downloads?
No. The estimator models page-view traffic only. Email flow, nightly backups, FTP uploads, database replication and large file downloads are excluded by design — on some plans those services exceed the web traffic, so budget them separately in GB per month.
Which WebJi® plans carry high transfer?
VPS and cloud tiers carry the most transfer; shared plans from ₹299 a month carry generous transfer for typical small sites. The desk matches your estimated GB to the right tier before you order, so send the estimate row in with your enquiry.
How often should I re-run the bandwidth estimate?
Rerun it whenever the inputs move: a redesign that changes page weight, a traffic campaign, a CDN move, or steady growth past your planning point. The estimate is only as current as the pageviews and page size you feed it, so pair it with your analytics' monthly view.
