Choosing between Genshin top-up packages starts with three numbers: how many wishes you still need, how many Primogems you already hold, and how much real money you are prepared to spend. One wish costs 160 Primogems, so 10 wishes require 1,600 and 50 require 8,000. A first-purchase double bonus can change a package’s effective cost by close to 50% per Crystal, which is why comparing sticker prices alone gives poor results. HoYoverse also reset first-top-up bonuses after the September 10, 2025 Luna I update, so bonus status must be checked before paying. Buy for the remaining wish requirement, not for the largest Crystal count.
A useful starting point is to turn the banner plan into Primogems before opening a payment page. If you want 30 additional wishes, the requirement is 4,800 Primogems. If your account already holds 1,920 Primogems and 6 Intertwined Fates, those 6 Fates represent another 960 Primogems of pulling power, leaving an effective shortage of 1,920. Buying enough for 5,000 or 6,000 extra Primogems would therefore leave a large unused balance unless you already plan to use it on another banner.
The difference becomes larger when the target rises. A 60-wish budget requires 9,600 Primogems, while 80 wishes require 12,800. Moving from 60 to 80 wishes increases the required currency by 33.3%, so package size should follow the number of pulls you are willing to fund rather than the visual gap between two store prices. Genshin Impact has used the 160-Primogem wish cost since its 2020 release, giving players a stable unit for comparing different purchase amounts.
If your estimated shortage is 2,400 Primogems, a purchase that covers roughly 2,400–3,000 is easier to justify than one that leaves several thousand unused simply because the unit rate looks better.
The next comparison is cost per usable Genesis Crystal. Divide the final amount charged by the total number of Crystals credited after any valid package bonus. A hypothetical $30 payment for 2,000 Crystals produces a rate of $0.015 per Crystal. If another $50 package provides 3,600, the rate falls to about $0.0139, around 7.4% lower. The larger package has a better unit rate, but spending $20 more to save 7.4% per unit is not automatically economical when the additional Crystals were not part of the original banner budget.
| Example purchase | Usable Crystals | Cost per Crystal | Wishes supported | Extra spending |
|---|---|---|---|---|
| $15 example | 1,000 | $0.0150 | 6.25 | — |
| $30 example | 2,000 | $0.0150 | 12.5 | +100% |
| $50 example | 3,600 | $0.0139 | 22.5 | +66.7% |
| $100 example | 8,000 | $0.0125 | 50 | +100% |
The figures above are calculation examples rather than current store prices, because regional pricing, taxes, currencies, and available packages can differ. The useful comparison is the relationship between final cost and currency received. Someone needing 12 wishes has a requirement of 1,920 Primogems. Paying for enough currency to support 50 wishes would provide more than four times the stated requirement even if the cost per Crystal were 15% lower.
First-purchase status can change the result much more than a small difference in package size. HoYoverse announced in August 2025 that every Genesis Crystal top-up level would regain its double first-top-up bonus after Version Luna I launched on September 10, 2025. The company also stated that unused double bonuses from before the reset would not stack with the new ones. A similar reset happened with Version 5.0 on August 28, 2024, again restoring a double bonus for the first purchase of each top-up level.
A double bonus is large enough to alter the comparison completely. If a tier normally provides X base Crystals and an eligible first purchase provides 2X, the initial effective quantity is 100% higher than the base amount. Once the double bonus has been used, the same tier may no longer have the same cost efficiency. Players comparing packages should therefore record bonus status tier by tier instead of assuming one previous purchase removed every possible first-purchase offer.
HoYoverse’s published reset history also shows why old screenshots should not be treated as current purchasing information. Official notices documented resets in 2021 for Version 2.1, 2022 for Version 3.1, 2023 for Version 4.1, 2024 for Version 5.0, and 2025 for Luna I. Store status visible on the player’s account at checkout is more useful than an article or video recorded several years earlier.
The timing of the purchase matters as much as the amount. Someone sitting at 50 available wishes who wants another 20 has a known requirement of 3,200 Primogems. Someone with no defined banner plan cannot make the same calculation because there is no upper spending boundary. Setting a cash limit before checking packages helps keep the comparison tied to the original goal. A player with a $40 ceiling should compare options at or below $40 rather than treating a $60 bundle as preferable because it provides 12% more Crystals per dollar.
Better unit pricing reduces the price of each Crystal; it does not reduce the total amount leaving your account.
Surplus currency deserves its own column in the comparison. Assume two purchase options provide 3,300 and 4,800 usable Crystals, while the account needs 3,200. The first leaves 100 unused, or about 3.1% of the requirement. The second leaves 1,600, equal to 50% of the requirement. If the second package costs substantially more, its lower unit rate is only useful when the remaining 1,600 Crystals already have a planned use.
That point matters when comparing a regular purchase with a cheap genshin top up offer from a third-party seller. The visible discount should be measured against the final checkout amount, currency delivered, account region, payment fees, delivery method, refund terms, and whether the seller requires information beyond what is reasonably needed to credit the account. A listed price 10% below another seller can lose most of the difference if a 6% payment fee and an unfavorable currency-conversion charge appear at checkout.
Account handling also deserves attention before price. Never provide a password, email verification code, two-factor authentication code, recovery code, or access to the email attached to the HoYoverse account just to receive a top-up. A seller that can deliver through a UID-based or otherwise authorized payment route should not need full login control. If a $5 saving requires handing over account credentials, the financial comparison is no longer limited to the $5 difference.
Payment currency can produce another measurable change. Suppose a package is displayed at the equivalent of $49.99 but your card adds a 3% foreign-transaction fee. The effective charge becomes roughly $51.49 before any other tax or payment cost. On a $99.99 purchase, the same 3% adds about $3.00. Comparing the checkout total rather than the product-page number keeps package comparisons consistent across cards, wallets, app stores, and regional storefronts.
Taxes should be handled the same way. If one checkout adds 8% sales tax and another price already includes applicable tax, two offers that appear equal can finish several dollars apart. For a $50 purchase, 8% adds $4; for $100, it adds $8. Record the amount that will actually be charged, then divide it by the usable Crystal amount. That gives a comparable figure even when payment systems present prices differently.
A second calculation should include free currency expected before the banner ends. Assume you want 25 more wishes, equal to 4,000 Primogems, but expect to obtain 1,200 Primogems from quests, events, commissions, or other confirmed in-game sources before the deadline. The paid shortage falls to 2,800, a 30% reduction. Buying before counting those sources can lead to purchasing currency that would have been earned through normal play a few days later.
Only count rewards you are likely to collect. Treating every possible event reward as guaranteed can understate the paid shortage, while ignoring confirmed rewards can overstate it. A conservative range works better: if you expect between 800 and 1,200 Primogems, calculate both cases. A 3,200-Primogem requirement then falls to 2,400 at the low estimate or 2,000 at the high estimate, a 16.7% difference between the two purchase targets.
Package combinations can also outperform one larger tier when first-purchase bonuses remain unused on several levels. Because HoYoverse’s 2025 notice states that each top-up level receives its own reset double bonus, two smaller eligible tiers may sometimes produce a different effective rate from repeatedly buying one already-used tier. Compare the credited amount shown for each eligible tier rather than assuming that the highest-priced option always provides the lowest effective rate.
The same method works when your wish target changes halfway through a banner. If you planned for 20 paid wishes and later decide you are comfortable funding 30, recalculate from 3,200 to 4,800 Primogems instead of purchasing another package by habit. The increase is 50%, so the cash budget should be reviewed again before payment. Keeping each purchase tied to a new numeric target makes several smaller transactions easier to evaluate than relying on the remaining Crystal balance alone.
