Tick value: how to calculate P&L in futures

Your platform shows the profit or loss of an open position in dollars, live. So why learn to calculate it?

Because the number you need is the one before the trade. How much does this stop cost? How far does price have to go to pay for the commissions? If I switch from ES to NQ, is a 10-point stop the same risk? None of those questions can wait until the position is open, and all of them come down to one figure: the tick value of the contract.

Four terms that get mixed up

Tick size is the minimum price increment. On NQ and ES it is 0.25 index points. On crude oil (CL) it is one cent. Price cannot move by less than one tick.

Multiplier (or contract size) is what one full unit of price is worth for one contract. NQ’s multiplier is $20 per index point; ES’s is $50. For CL, one contract is 1,000 barrels, so a one-dollar move in the price of a barrel is worth $1,000.

Tick value is the tick size times the multiplier: what one tick is worth for one contract. NQ: 0.25 × 20 = $5. ES: 0.25 × 50 = $12.50. CL: 0.01 × 1,000 = $10.

Point value is the value of a one-point move, which on index futures is simply the multiplier. On NQ, four ticks make a point, so 4 × 5 = $20.

The confusion usually comes from mixing points and ticks. “My stop was 10” means nothing until you say 10 what. Ten points on NQ is 40 ticks. Ten ticks is two and a half points.

The P&L formula

For a long position:

P&L = (exit price − entry price) ÷ tick size × tick value × number of contracts

For a short, flip the subtraction: entry minus exit. The middle part, the price difference divided by the tick size, just counts how many ticks the trade moved. Everything else is multiplication.

Then subtract costs. Commissions and exchange fees are charged per contract, per side, so a round turn (entry and exit) costs twice the per-side amount, for each contract. What you get after that is the net result, the one that actually reaches the account.

Worked examples

The prices below are made up to keep the arithmetic readable.

Long 2 NQ. Suppose you buy 2 NQ at 100.00 and sell at 103.25. The move is 3.25 points, which is 13 ticks. 13 × $5 × 2 contracts = $130 gross.

Short 1 ES. You sell 1 ES at 50.00 and buy back at 51.50. The trade went against you by 1.50 points, 6 ticks. 6 × 12.50 = $75 lost, before costs.

Long 3 MNQ. Same 13-tick move as the first example, on micros. 13 × 0.50 × 3 = $19.50. The micro is exactly one tenth of the mini, so 3 MNQ on that move earn what 0.3 NQ would.

Long 1 CL. You buy crude at 70.00 and sell at 70.35. That is 35 cents, so 35 ticks. 35 × 10 = $350.

Notice that CL in the last example moved “only 35 cents” and paid more than the two NQ contracts did. That is why comparing instruments in points or in cents is useless. Compare them in dollars per tick, and in how many ticks they usually move.

A reference table

Tick specifications for the contracts most day traders meet. Each micro is one tenth of its mini.

Two of those deserve a second look. YM ticks in whole points, so on the Dow one point is one tick, unlike the quarter points of NQ and ES. And RTY ticks in tenths, so ten ticks make a point. Whenever you pick up a new contract, check the tick size before you even open the chart.

These specifications are stable, but exchanges can change contract terms. Before trading a contract for the first time, check them against the specification the exchange publishes.

Thinking in ticks, deciding in dollars

While the trade is on, think in ticks. Your stop is 24 ticks away, the target is 48 ticks away, price is 10 ticks in your favor. Ticks are tied to the chart and do not change when you change size. Dollars are for the decisions before and after the trade: is this stop affordable, and what did the day cost.

The people who get hurt by tick value are rarely the ones who never learned the formula. They are the ones who learned it on one contract and then moved to another without redoing the math. A 20-tick stop on MES costs $25 per contract. Carry the same habit over to ES and that stop costs $250, ten times as much, on a chart that looks exactly the same.

Cases the simple formula does not cover

Partial fills and scaling. If you entered in pieces at different prices, the formula works on the average entry price. Platforms calculate it for you; on paper, weight each piece by its size.

Slippage is measured in ticks too. A stop that fills 2 ticks past its price on NQ costs 10 extra dollars per contract. On ES it costs 25. Fast markets make this real money.

Contracts in other currencies. Some futures (European index contracts, for example) are priced in another currency, so the tick value is in euros, not dollars. Converting them to your account currency adds an exchange-rate step.

Expiration months. The tick value is the same for every expiration month of the same contract. What changes between months is the price, not the math.

Mini analysis, micro execution

Since the mini and its micro trade at the same price, the only term that changes in the formula is the tick value: $5 becomes $0.50 on the Nasdaq, $12.50 becomes $1.25 on the S&P. That is what makes it reasonable to read the auction on the mini, where the volume is, and size the position on the micro. In EliteXCharts, Cross Trade pairs them for you across six contracts, CL to MCL and GC to MGC included, and the open P&L you watch is already in the micro’s dollars.

Futures trading involves substantial risk of loss and is not suitable for every investor. All trades in this post are hypothetical examples.
