How this calculator works
Add each investment account, like a brokerage account, 401(k), or IRA, and enter the market value your statement or app shows, as often or as rarely as you like. If you update only some accounts, the others keep their last value. The chart shows your total over time, green where the market moved your portfolio up and red where it moved it down. Money you deposit or withdraw is entered separately so it is not counted as a gain or loss, which gives you an honest picture of how your investments performed.
A worked example
Suppose you have a brokerage account and a 401(k). On January 2 you enter $80,000 and $120,000, for a total of $200,000. On April 1 your statements show $83,000 and $126,600, and you note that $3,000 of new contributions went in during those months.
The total rose by $9,600, from $200,000 to $209,600. But $3,000 of that was your own money, so the market gain is $6,600, or 3.3%. The tracker draws that stretch of the chart in green. If the next entry is lower after allowing for deposits, that stretch is drawn in red.
How to read your results
The line shows your total on each date you entered, with the spacing based on the actual dates. Green means the market moved your portfolio up between two entries, and red means it moved it down. Deposits and withdrawals do not change the color.
"Market gain" for the year is the change in your total since the start of that year (your last entry before it, or your first entry of the year), minus the money you added and plus the money you took out. It is a simple measure. It is not the time-weighted return that fund companies report, but it answers the question most people have: how much did my investments earn?
Common mistakes to avoid
- Leaving out contributions. If you skip the money-added box, every deposit looks like a market gain and the picture is too rosy.
- Checking every day. Daily values are noise. Once a month or once a quarter is enough to see the trend.
- Mixing in cash and your home. This page is for investment accounts. Use the Net worth tracker for the full picture of what you own and owe.
Common questions
How often should I enter values?
As often as you like: monthly, quarterly, or whenever you check your statements. The chart spaces entries by date, so irregular updates still show an accurate picture.
Why enter money added or withdrawn?
Deposits and withdrawals change your balance without being market gains or losses. Entering them separately lets the tracker show how much your investments actually earned.
Is my account information safe?
Nothing is linked to your accounts and no login is needed. The values you type are saved only in your browser on your device and included in your backups.
What is the difference between this and the Net worth tracker?
The Net worth tracker adds up everything you own and owe once a month. The Portfolio tracker follows only your investment accounts, on any dates you choose, and separates market movement from your own deposits.
What if I only update one account?
Leave the others blank. Each account keeps its last entered value until you update it, and carried-forward values are marked in the table.
Can I export my entries?
Yes. The Download for Excel button saves every date, account value, money added or withdrawn, total, and gain as a CSV file.
