fgo save calculator

What this FGO save calculator does

This tool helps you answer one practical question: “If I keep saving, what are my odds on banner day?” It combines your current resources (Saint Quartz and tickets), your monthly income, and your desired timeline to estimate your total summons. Then it calculates the probability of getting your target rate-up Servant at least once (or multiple copies if you set a higher NP goal).

Instead of guessing, you get a clear plan with numbers: projected pulls, success chance, and how far you are from a confidence target.

How the calculator models summons

1) Resource projection

The planner estimates future resources by adding your current stash to your expected monthly income over the number of days until the banner. Values are rounded down to avoid overpromising.

2) Quartz-to-pull conversion

It assumes normal FGO summon economics:

• 30 SQ = 11 summons (multi roll bonus included)
• 3 SQ = 1 summon for singles
• 1 ticket = 1 summon

3) Probability calculation

For each summon, the tool uses your rate-up chance input (for example, 0.8% for a solo SSR rate-up). It calculates the chance of getting at least your target number of copies using a binomial distribution.

What to enter for best accuracy

• Current SQ and tickets: include everything you actually plan to spend on this banner.
• Monthly income: use your own average from login bonuses, events, missions, interludes, and maintenance rewards.
• Days until banner: estimate as closely as possible from server schedule expectations.
• Rate-up chance: for most solo SSR banners, 0.8% is common; adjust if your target banner differs.
• Target copies: use 1 for NP1, 2 for NP2, etc.

Example planning workflow

Suppose you have 180 SQ and 20 tickets, gain roughly 120 SQ and 15 tickets per month, and your banner is in 120 days. The calculator projects your total summons and immediately shows your pull odds for NP1 at 0.8%. If your confidence is below your comfort level (say 70%), you can decide early whether to:

• Skip upcoming banners entirely,
• Farm every event and mission aggressively,
• Lower your NP target from NP2 to NP1, or
• Prepare backup targets in case of bad luck.

Important limitations

This is a planning calculator, not a guarantee engine. Gacha outcomes are random, and even high probabilities can fail in individual cases. Also, the model does not automatically predict special campaigns or unexpected changes unless you include them in your monthly income estimate.

• No “luck correction” is possible in probability math.
• Small differences in rates can significantly change outcomes over many pulls.
• Your real SQ income can vary from month to month.

Final advice for FGO savers

Good saving strategy is less about perfect forecasting and more about consistency. Check your plan once a month, update your real gains, and keep your priorities clear. If a banner is truly your top target, this calculator helps you protect that goal from impulse spending.

Plan early, adjust often, and let math do the emotional heavy lifting.
