ESTIMATED LOT SIZE
How the Lot Size Calculator Works
Lot size conversion estimates total units from a selected lot type, number of lots, and units-per-lot assumption. Actual contract sizes may vary by broker, exchange, instrument, and account type.
The Formulas
Total Units:
Total Units = Number of Lots × Units per LotLot Equivalents:
Standard Lot Equivalent = Total Units / Standard Lot UnitsMini Lot Equivalent = Total Units / Mini Lot UnitsMicro Lot Equivalent = Total Units / Micro Lot UnitsAssumptions
Results may vary by broker, exchange, instrument, contract size, fees, and market conditions.
Example Calculation
Forex Example:
- Instrument Type: Forex
- Lot Type: Standard
- Number of Lots: 1
- Units per Lot: 100,000
- Calculate Total Units: 1 × 100,000 = 100,000
- Calculate Standard Lot Equivalent: 100,000 / 100,000 = 1.00
- Calculate Mini Lot Equivalent: 100,000 / 10,000 = 10.00
- Calculate Micro Lot Equivalent: 100,000 / 1,000 = 100.00
Frequently Asked Questions
What does this lot size calculator estimate?
Lot size conversion estimates total units from a selected lot type, number of lots, and units-per-lot assumption. Actual contract sizes may vary by broker, exchange, instrument, and account type.
Are lot sizes the same for forex, crypto, and gold?
No, default assumptions vary significantly. For example, a standard forex lot is typically 100,000 units, while a standard gold lot is often 100 units. A standard crypto lot is usually 1 unit, but this depends on the exchange.
Can I change the units per lot?
Yes, the calculator auto-fills the typical assumptions for each market and lot type, but you can manually edit the units per lot to match your specific broker settings.
