Mercury Pricing in May 2026

Mercury's pricing for the core banking product is $0/month — Mercury makes money on interest spread and FX rather than subscription. Mercury Treasury (yield product on excess cash) earns ~4-5% APY currently with no separate fees. Mercury IO (working capital line of credit) prices on outstanding balance. Real-world Mercury costs are essentially zero for most startups; advanced features (Mercury Plus at $35/month for spend limits, expense management) are optional.

The $500 account bonus is genuinely valuable for early-stage startups — most spend is rewarded with cashback (typically 1-1.5% on most categories). Eligibility focuses on US-incorporated startups with $50K+ in deposits or active venture funding. The strategic decision: Mercury vs traditional banks vs newer challengers is the active comparison in startup banking. Mercury's value is the founder-experience and integrations — onboarding in minutes, clean UI, deep integrations with Stripe/QuickBooks/Brex. The bonus is best treated as the on-ramp, not the value driver. For most venture-backed startups, the actual value is Mercury Treasury for parking unused capital at 4-5% APY (versus 0.05% at traditional banks) — on $1M cash balance, that's ~$45K/year in yield difference. The $500 bonus plus Treasury yield easily exceeds traditional bank value within the first month. For non-US-incorporated startups, Mercury isn't accessible; alternatives like Wise Business, Brex Cash, or local fintechs (Tide for UK, Qonto for EU) play similar roles.
