An annual VPN plan can advertise a lower monthly equivalent than a month-to-month subscription, but the headline rate does not tell you whether you will save money. The deciding factors are the amount charged upfront, how long you expect to keep using the service, what happens at renewal, and whether the refund terms cover your situation. Compare the total cost over the time you will actually use the plan, not just the number beside “per month.”
There is also an important distinction between a discount and a commitment. A lower rate is valuable only if you use the service long enough to benefit from it and can afford the initial payment without putting other expenses at risk. This guide provides a calculation method, a checklist for reviewing renewal and refund conditions, and a practical way to compare offers without assuming that every provider has the same plan structure.
Compare total cost, not the advertised monthly rate
An annual offer is usually paid as one upfront charge, even when its marketing presents the amount as a monthly equivalent. To compare it with a monthly plan, write down the actual amount due today, the period it covers, and any later renewal price. Then compare that total with what you would pay for the same period on a monthly subscription.
Use a simple model. Let A be the annual payment, M the price of a monthly subscription, and n the number of months you expect to use the service. The annual plan’s advertised monthly equivalent is A ÷ 12, while the monthly plan’s cost over your expected use is M × n. These figures are useful only when you compare equivalent service periods and include any taxes or fees shown at checkout. If you might cancel before the annual term ends, do not assume the unused portion will be refunded; check the policy first.
VPNBM lists monthly subscriptions rather than an annual price in its published plan information. Its monthly options are ¥9.9 per month with 60GB, ¥18 per month with 250GB, and ¥28 per month with 500GB. Since there is no annual price in that list to compare, a responsible comparison should not invent a yearly discount or imply that paying for a year is available. Check the current checkout details before purchasing, because the amount and terms displayed at the time of payment are the ones to rely on.
| What to compare | Monthly subscription | Annual offer |
|---|---|---|
| Payment due now | The charge for the current billing period | The full amount collected upfront, including any listed fees |
| Comparable cost | Monthly price multiplied by the time you expect to use it | Actual upfront amount for the covered period, not only its monthly equivalent |
| Cancellation risk | Usually limited to the unused portion of the current period, subject to the terms | Check whether ending early changes eligibility for a refund |
| Renewal | Check the next billing date and recurring amount | Check the renewal period, price, and whether renewal is automatic |
| Usage allowance | Confirm how much data is included and when it resets | Confirm the allowance for each billing period and whether it carries over |
A low monthly equivalent can still cost more for your circumstances if you stop using the service early. Conversely, if you are confident that you will use the same provider throughout the covered term, have checked the renewal amount, and can pay upfront comfortably, an annual offer may be worth considering. The calculation is a decision aid, not a guarantee that one billing period is best for everyone.
Check renewal and refund terms before paying
Promotional pricing and renewal pricing may differ. Before placing an order, look for the amount that will be charged at renewal, the date of that charge, and the duration of the renewal period. A plan described as a deal may apply only to the first term. If the renewal price is not visible on the checkout screen, look in the provider’s billing terms or ask support to confirm it in writing before paying.
Read the cancellation instructions as carefully as the price. Find out whether turning off automatic renewal stops future charges while leaving the current service active, or whether cancellation ends access immediately. Also check whether a refund is calculated for unused time, whether a processing fee applies, and whether the refund policy is limited to an initial purchase. These conditions can change the real cost of leaving early.
VPNBM states a 14-day money-back guarantee. Treat a refund window as a way to evaluate a first purchase under the stated terms, not as a substitute for checking whether a long commitment fits your budget. Read the current policy for eligibility, how to submit a request, and what information is required. Do not assume that a renewal or a later purchase automatically receives the same treatment as a first payment.

Do not compare plans on cost alone. Check whether the allowance is enough for your normal use, whether your preferred devices and client apps are supported, and whether the plan’s renewal conditions are clear. If you are still comparing providers and connection requirements, the VPN That Works in China page is one place to review the service information before you decide what to test.
A practical way to run the comparison
Use the following steps while you have the checkout page and plan terms open. Keep notes or save the relevant text so that you can compare offers later without relying on a promotional banner that may no longer show the full conditions.
- Write down your expected use period. Estimate how long you genuinely expect to need the service. If your travel, work, or study plans are uncertain, compare a shorter commitment rather than assuming you will use the service for a full year.
- Record the real amount due today. Note the complete checkout total and the period it covers. Do not use a monthly equivalent as the upfront cost.
- Calculate the alternative. Multiply the monthly price by the number of months in your expected use period. Compare the result with the annual payment only if the covered periods are equivalent.
- Check the renewal line. Record when renewal happens, whether it is automatic, and the price and term that will apply. If the renewal amount is unclear, ask before purchasing.
- Read cancellation and refund conditions. Confirm the applicable deadline, eligibility, request method, and whether the terms differ between an initial purchase and a renewal.
- Match the data allowance to your habits. Consider video, downloads, calls, and everyday browsing across the devices you use. Do not choose a cheaper tier if it is likely to cause you to run out of data or buy more than you need.
- Save a copy of the offer. Keep the order confirmation and the terms that applied when you paid. This makes it easier to verify what you agreed to if a renewal or cancellation question comes up.
As you compare, separate the service evaluation from the billing decision. First confirm that the client works on your devices, that the routes you need are available, and that performance is acceptable on your networks. Then choose a billing period. Paying for a long term before checking everyday compatibility can turn a nominal discount into an expensive mismatch.
Monthly subscriptions and traffic packs are not the same
Some services offer more than one way to pay, and not every option is a monthly or annual subscription. VPNBM also lists traffic packs that remain valid until used and do not expire: ¥158 for 300GB, ¥358 for 1000GB, and ¥658 for 3000GB. These are not annual plans, so do not compare them as if they provide a fixed number of months of service. Their value depends on how much data you use and how long it takes you to use it.
For a monthly subscription, VPNBM says traffic resets each month on the activation date. If you upgrade partway through a billing period, the price difference is calculated according to the remaining days. That detail matters when you estimate the cost of changing tiers: the allowance and billing period are not necessarily equivalent to a data pack that stays available until consumed. Check the plan information in your account before making a change, and avoid assuming that unused monthly data carries into the next period.
A traffic pack may suit someone whose usage is occasional or uneven, while a monthly subscription may be easier to budget for regular use. That is a pattern to test against your own usage, not a promise that one type always costs less. Estimate your typical data needs, consider whether they vary between months, and compare the terms that apply to the exact option you intend to buy.
Choose the plan that fits your budget and usage
An annual deal is most compelling when the provider’s service already meets your needs, the full upfront charge is affordable, you expect to remain a customer for the covered period, and the renewal terms are transparent. A monthly plan is often the more cautious choice when you are testing a service, your plans may change, or you want to limit the amount committed before you know how well it works for you. Neither choice is automatically the best value without the terms and your expected use.
- ✅ Compare the full amount due today, not just the advertised monthly equivalent.
- ✅ Confirm the renewal date, recurring price, and renewal period before checkout.
- ✅ Check the refund conditions and do not assume they apply to every renewal.
- ✅ Match the data allowance and reset rules to your actual usage.
- ❌ Do not treat a traffic pack as an annual subscription or assume unused monthly data rolls over.
- ❌ Do not choose a long commitment solely because its displayed monthly rate looks lower.
Before paying, make sure you can explain the offer in one sentence: what you will pay now, what period that covers, what you will pay at renewal, and what happens if you stop using the service early. If any part is uncertain, pause and verify it with the provider. A clear monthly plan can be better value than an attractive annual headline when flexibility matters; a verified annual offer can make sense when the full commitment fits both your usage and your budget.
