Average Price / Average Down Calculator

It shows the exact volume-weighted average after each new buy. A trader who has already bought three times and is thinking about a fourth can see, in seconds, whether the next lot actually moves the average enough to matter or just increases risk. Most people guess this number. The calculator removes the guess.

Broker apps usually show only the latest fill or a simple average. When you have staggered entries at different sizes, the real average is weighted by quantity. The calculator forces that math. A trader who scales in over five minutes can check the true average before the next order instead of after the trade is already worse.

Use it when you buy the same option (or a related strike) in more than one clip. If the first lot was 10 contracts at ₹45 and the second is 25 contracts at ₹38, the calculator shows the blended premium. That number is what you need for a realistic breakeven, not the last fill price.

Yes. Enter the previous tranches and the planned next quantity and price. The tool shows the new average and how much capital is now at risk. A trader who has been adding to Bitcoin every dip for three weeks can decide whether one more buy is worth the added exposure or whether the average is already low enough.

It does. Each row takes its own quantity. A Nifty futures trader who bought 2 lots at 22,400 and later added 5 lots at 22,150 gets a true weighted average, not an unweighted midpoint. The same logic works for stock options where lot size is fixed but the number of lots changes.

The calculator shows the limited effect. A small add against a large first position barely moves the average. Traders who keep adding tiny amounts and then wonder why the average “didn’t come down” can see the math before they place the order. The tool makes the Martingale risk visible instead of theoretical.

Both use it. A portfolio investor who bought a stock in three tranches over six months can enter the quantities and prices and get one clean average for tax or performance tracking. A discretionary trader who scales into a position over an hour uses the same numbers for risk decisions. The calculator does not care about the holding period.

It shows the new average and the total capital committed after the next buy. If the projected average is only a few points lower but the position size doubles, the trader can see that the risk increase is larger than the average improvement. That comparison is what most people skip when they are already in a loss.
