Binance and Bybit maintenance-margin bracket reference

your maintenance-margin rate is selected by position notional, symbol and venue. leverage does not directly select the bracket. it controls initial margin and must remain within the bracket’s maximum, but a BTC position with $10,000 notional uses the same first-bracket MMR whether it is running at 5x, 20x or 100x, provided that leverage is permitted for that bracket.

notional is the position’s contract exposure, not the margin posted against it. if the mark moves in your favor while contract quantity stays unchanged, notional can rise enough to cross a bracket ceiling. the venue can then apply a higher MMR and lower maximum leverage. that MMR change moves an isolated long liq upward and an isolated short liq downward, pulling either estimate toward entry.

the tables here cover USDT-M isolated margin for BTC, ETH and SOL. every liquidation figure remains an estimate — exchanges compute exact liq from live margin; always double-check on your venue. cross margin, unrealised PnL on other positions, and fee or funding accruals since entry are not represented by the isolated approximation used in the worked calculations.

Binance uses separate notional ladders by symbol. BTC and ETH share the same first 4 ceilings and rates, while their fifth ceilings differ: BTC extends to $70,000,000 and ETH to $50,000,000 at 2% MMR. SOL starts at 0.5% MMR up to $50,000 and reaches 2.5% by its fifth listed bracket.

the maximum-leverage column is a bracket constraint, not the input that chooses MMR. for example, BTC notional up to $300,000 carries 0.4% MMR and permits up to 150x. once BTC notional exceeds $300,000 and remains within $800,000, MMR becomes 0.5% and maximum leverage becomes 100x, regardless of the leverage that originally opened the position.

for SOL, the ladder tightens sooner in dollar terms. its first ceiling is $50,000 at 0.5% MMR and 100x maximum leverage. the next ceiling is $400,000 at 0.65% and 75x, while the fifth listed bracket ends at $8,000,000 with 2.5% MMR and 20x maximum leverage.

Bybit’s risk-limit endpoint also maps notional to MMR and maximum leverage, but its ceilings differ from Binance. BTC and ETH begin with 0.33% MMR up to $300,000 and 150x maximum leverage. their second brackets use 0.5% MMR and 100x, ending at $2,000,000 for BTC and $900,000 for ETH.

the later Bybit BTC brackets are narrower: $2,600,000 at 0.56% MMR and 90x, $3,200,000 at 0.63% and 80x, then $3,800,000 at 0.67% and 75x. ETH follows the same sequence of rates and leverage caps, but its corresponding ceilings are $1,200,000, $1,500,000 and $1,800,000.

Bybit SOL begins identically to Binance SOL at $50,000, 0.5% MMR and 100x maximum leverage. the ladders split after that point. Bybit’s next listed SOL ceilings are $100,000, $250,000, $400,000 and $550,000, with MMR rising from 0.56% through 0.71% as maximum leverage falls from 90x to 70x.

yes. contract quantity can stay fixed while a favorable mark move increases the position’s notional. if that notional crosses a risk-limit ceiling, the applicable MMR can rise even though you did not change leverage or add contracts. the bracket shift therefore consumes part of the liq distance created by the favorable move; it does not require a leverage-slider change.

consider isolated BTC entered at $97,400 with 20x leverage. on Binance, notional up to $300,000 uses 0.4% MMR, producing a $92,919.60 long-liq estimate. above $300,000 and up to $800,000, the 0.5% MMR gives $93,017.00. the estimate moves $97.40 toward entry because $97,400 × (0.5% − 0.4%) = $97.40.

the same threshold produces a larger shift from Bybit’s first bracket. up to $300,000, 0.33% MMR gives a $92,851.42 long-liq estimate. above that ceiling and through $2,000,000, 0.5% gives $93,017.00. the $165.58 movement toward entry is $97,400 × (0.5% − 0.33%). shorts move toward entry by the same dollar amount under this approximation.

the isolated USDT-M approximation for a long is liq = entry × (1 − 1/leverage + MMR). for a short it is liq = entry × (1 + 1/leverage − MMR). a higher MMR raises the long result and lowers the short result. both changes narrow the distance from entry, which is why resolving the correct notional bracket must happen before calculating liq.

at a $97,400 BTC entry, $10,000 notional and 20x, Binance applies 0.4% MMR. the long estimate is $97,400 × (1 − 1/20 + 0.004) = $92,919.60. the short estimate is $97,400 × (1 + 1/20 − 0.004) = $101,880.40. both sit 4.6%, or $4,480.40, from entry under the approximation.

symbol-specific MMR changes the result even when notional and leverage match. with SOL entered at $214, $10,000 notional and 20x, both venue tables apply 0.5% MMR. the estimated long liq is $204.37 and the short liq is $223.63, leaving $9.63 or 4.5% of room. exact live-margin output can differ after funding, fees or other account-level adjustments.

the reference prints only the first 5 brackets for each symbol. above the last listed ceiling, the calculator falls back to the fifth listed MMR. because later venue brackets can carry higher maintenance rates, that fallback slightly underestimates MMR and can place the estimated liq farther from entry than the venue’s live calculation for a very large position.

the coverage boundary differs sharply by venue and symbol. Binance’s fifth listed ceilings are $70,000,000 for BTC, $50,000,000 for ETH and $8,000,000 for SOL. Bybit’s are $3,800,000 for BTC, $1,800,000 for ETH and $550,000 for SOL. notionals above those values require the venue’s current higher-bracket data rather than treating the fifth rate as final.

brackets can also change at the venue level after publication. these rows were checked against live exchange data on 2026-09-19: Binance through the bracket API behind its official leverage-margin page, and Bybit through its public v5 market risk-limit endpoint. the verification date is part of the reference because an undated MMR table is not sufficient input for a liq calculation.

a usable bracket lookup starts with venue, symbol, margin mode and current notional. entry and leverage are not enough because the same leverage can sit inside several MMR tiers. for isolated calculations, select the first ceiling that contains the position’s notional, then carry that bracket’s MMR into the long or short formula.

the resulting number remains an estimate rather than an exchange settlement value. live margin can reflect funding accruals, fees and venue-side adjustments absent from the approximation. conditional-order trigger type is selectable and varies by product and interface, so it must be checked on the account rather than assumed from the liq calculation.

1. identify Binance or Bybit and the exact BTC, ETH or SOL contract before reading the ladder.
2. calculate position notional before selecting MMR; do not use posted margin as the bracket input.
3. take the MMR and maximum leverage from the same row rather than mixing adjacent brackets.
4. recalculate after notional crosses $300,000 for BTC or ETH, or $50,000 for SOL in the first listed ladders.
5. treat output above the fifth listed ceiling as understated and double-check the live venue bracket.
