Average down calculator that saves every trade. Buys, sells, fees — no login.
Know your new average before you buy more.
AvgNote is a stock average calculator and trade ledger in one. Type your current average price and the shares you plan to add — the new average appears as you type. No calculate button, no ads between every result, and nothing disappears when you close the app.
AVERAGE DOWN CALCULATOR
• Enter your average and quantity, then add as many planned buys as you like
• Enter by shares or by amount ("buy $500 worth")
• See the new average, total shares and extra cash needed
• Reverse mode: set a target average and see exactly how many shares it takes at a given price
• One sentence explains the result: "Buying 50 more shares lowers your average by 2.26 (2.98%)."
TRADE LEDGER THAT REMEMBERS
• Keep a list of your stocks, ETFs or coins — name them however you like
• Log buys and sells with date, price, quantity and fee

• Log a planned average down to your ledger in one tap
