Fate/Grand Order's gacha is the Saint Quartz summon. It predates the pity era and, below its one guarantee, still works the way Japanese mobile gachas worked in 2015: flat rates, no ramps, no coin flips. [[1]](#ref-1)

## Rates and costs

| Parameter | Value |
| --- | --- |
| 5-star (SSR) servant | 1% |
| 4-star (SR) servant | 3% |
| Rest of pool | 3-star servants and Craft Essences of all rarities |
| Single roll | 3 Saint Quartz or 1 Summon Ticket |
| 11-roll multi | 30 Saint Quartz (10 plus 1 bonus, standard since 2019) |

On a rate-up banner the overall SSR rate stays 1%; a solo featured servant typically takes about 0.7 points of it, a split the community documents from the in-game disclosure. [[1]](#ref-1) The rest of the 1% goes to the permanent pool, so "spooks" (off-banner SSRs) are a routine outcome. This is the classic fractional [rate-up](/wiki/rate-up), not a 50/50: an off-banner SSR gives no protection toward the featured one.

Craft Essences matter for cost modeling: a large share of high-rarity results are equipment cards rather than servants, which is why FGO budgets should count only servant rates, not "SSR anything" rates.

## What the math looks like

At a flat 1% with no soft pity, the median first SSR servant arrives around roll 69, but the featured servant at 0.7% has a median near roll 99, and 1 player in 20 would pass roll 425 without them. Those tails are why the [330-roll guarantee](/fate-grand-order/wiki/guaranteed-summon) was eventually added, and why the game remains the reference example in the [pull probability article](/wiki/gacha-probability) for pre-pity design.

There is no exchange system below the guarantee, no escalation, and no carry-over of anything between banners.
