UK100 Pip Value Calculator

Knowing what one point of UK100 is actually worth, before you size a trade, is what this calculator answers — using UK100's own real contract size and point value rather than a flat forex assumption.

How do I calculate pip value for UK100?

At UK100's stored contract size (1 units per lot), here's what one point of movement is worth at three common lot sizes.

Say a trader opens 1.00 lot of UK100, with a stop loss 64 points away and a take profit 128 points away.

Why does pip value change between instruments?

Pip/point value depends on an instrument's own contract size convention and current price, not a universal rule. UK100 is worth $1.33 per point per lot at its stored contract size — a different contract size (common across brokers for indices) would scale that figure directly.

Why is pip calculation different for non-standard-decimal instruments like this one?

Most forex majors use a 4-decimal pip convention, but plenty of instruments don't: JPY pairs use 2 decimals, and UK100 uses its own quoting convention (one point here equals a raw price move of 1). This calculator uses UK100's own real pip/point size rather than assuming the generic 4-decimal convention, which would silently miscount the move.

What one point means on UK100

The index is priced in pounds, so its dollar point value moves with GBP/USD, and a weaker pound tends to lift it because overseas earnings are worth more in pounds.

On this site one point for UK100 is 1 in price. If UK100 rose from 10,700.0 to 10,740.0, the move is 40.0 ÷ 1 = 40 points.

How the value per point is calculated

For one lot: 1 × 1 = 1 GBP per point for 1 lot; assuming 1 GBP = $1.32, that is $1.32. Everything below uses $1.32 per point for 1.00 lot.

UK100 value per point at common lot sizes

• 1.00 lot: 1.00 × $1.32 = $1.32 per point.
• 0.10 lots: 0.10 × $1.32 = $0.132 per point.
• 0.01 lots: 0.01 × $1.32 = $0.0132 per point.
• 5.00 lots: 5.00 × $1.32 = $6.60 per point.

Value per point grows in direct proportion to lot size, so doubling the lots doubles both the gain and the loss for every point price moves.

Worked example: what a stop costs on 0.30 lots of UK100

• Entry 10,700.0, stop 10,660.0: the distance is 40 points.
• Value per point on 0.30 lots: 0.30 × $1.32 = $0.396.
• Money at risk if the stop is hit: 40 × 0.30 × $1.32 = $15.84.
• Spread of 3 points (an invented figure for this example): 3 × 0.30 × $1.32 = $1.19, which is 7.5% of the stop distance.

Spreads are wider at the open and in Asian hours. On a 40 point stop the spread above takes 7.5% of the room before price moves at all, and on a stop half as wide, 20 points, it would take 15%.

Risk at other stop distances on 0.10 lots

• 20 points: 20 × 0.10 × $1.32 = $2.64.
• 40 points: 40 × 0.10 × $1.32 = $5.28.
• 80 points: 80 × 0.10 × $1.32 = $10.56.
• 160 points: 160 × 0.10 × $1.32 = $21.12.

Each doubling of the stop doubles the money at risk on the same lot size, which is why a wider stop needs a smaller position to keep the risk the same.

Working backwards: how far can the stop be?

Sometimes the lot size is fixed and the question is how wide the stop may be. Say you hold 0.10 lots of UK100 and will risk $100.

• Value per point on 0.10 lots: 0.10 × $1.32 = $0.132.
• Stop distance: $100 ÷ $0.132 = 757.6, rounded down to 757 points.
• Check: 757 × 0.10 × $1.32 = $99.92, inside the $100 budget.
• In price terms, 757 × 1 = 757.0, so a buy at 10,700.0 would have its stop at 9,943.0.

If that stop is too tight for how UK100 actually moves, the answer is fewer lots, not a stop that sits inside the normal noise. The UK100 lot size calculator does that step for you.

Does the value per point change?

Yes, because UK100 is quoted in GBP. The value per point is converted to US dollars at the going rate, so it moves with that rate. Suppose GBP loses 5% against the dollar: one GBP falls from $1.32 to $1.32 × 0.95 = $1.254, and the value per point for 1 lot becomes 1 × $1.254 = $1.25 instead of $1.32. Re-check the value when the rate has moved a lot, especially before sizing a long-held position.

Verify the UK100 point value with your broker

The contract size of 1 and the point size of 1 are reference values. Brokers can define a point or pip differently and quote an extra decimal, so compare $1.32 per point with the tick value in your platform's contract specification. For background on the instrument, see the FTSE 100 on Wikipedia.

Where to find the UK100 value in your platform

• Open the contract specification for UK100 (in MetaTrader, right-click the symbol in Market Watch and choose Specification).
• Check the contract size: this page assumes 1.
• Check the tick size and tick value, then scale to one point of 1 if they differ.
• Compare the result with $1.32 per point per lot; a gap of more than a few percent usually means a different contract size or a different conversion rate.

Conclusion

This only holds if 1 units per lot is actually your own broker's real contract size for UK100 — it's a figure that varies by broker, especially outside plain forex majors. Always confirm your own platform's UK100 specification (Market Watch, then Specification) before trusting a pip/point value for a real trade. See the difference between points and pips, Wikipedia's entry on percentage in point (pip) for the underlying concept, and real MT4 screenshots comparing pip value across different lot sizes.
