Portfolio Calculator
A portfolio is a pie. This tool shows how big each slice really is, in percent.
Type each holding and see the weights side by side. Heavy in one spot? You will see it at once.
The buy and sell hints show what it would take to get back to your targets. Many investors do this a few times a year.
How to use this tool
- 1All holding values add up to the total.
- 2Each value split by the total gives its weight.
- 3The biggest slice row flags a heavy bet.
The math behind it
Mix percent = holding value / total portfolio x 100
One holding at 8,000 in a 40,000 portfolio is 20 percent.
Type your holdings and the tool shows your full mix.
Who this tool is for
I watch which tools folk open most, and this one gets used by the same kinds of people again and again. If any of these sound like you, you are in the right place.
- Investors checking a mix against a target
- Folk who add money with out ever trimming
- Any one who owns five things that all move to gether
I once thought I was diversified because I owned five things. This tool showed me four of them were the same bet in different hats. One slice was 68 percent of the pie. Rebalancing felt boring right up until the month it saved my year.
Tips from me
- Check your mix twice a year. Drift is quiet and real.
- If one line is over half, you own that line's bad days too.
- Rebalance by adding to the light side first. It is the calmest way.
Mistakes I see with this sum
These are the three slips I made my self or watch folk make most. Skip them and your number will be closer to the truth on the first try.
- 1Setting targets and never checking drift. Winners grow, plans fade.
- 2Rebalancing every week. A few times a year is plenty for most.
- 3Owning many things and calling it a mix. Overlap is not mix.
Two words worth knowing
Drift
How far a slice has wandered from its target.
Rebalance
Buying and trimming to bring the mix back to target.
That is the whole page. The tool does the math, and the words above give it a shape. If a number still looks odd, change an input and watch what moves. Playing with the boxes taught me more than any guide did.
Common questions
+What is a good mix?
It depends on your age and nerves. A common start is more steady funds with a small slice of spicy bets.
+How often should I check my mix?
A few times a year is plenty. Daily watching tends to breed bad moves more than good ones.
+What is a balanced mix?
It is personal. Growth folk hold more of the fast lines, calm folk more of the steady ones. The percent view makes your true mix visible.
+How often should I rebalance?
Once or twice a year, or when a line drifts far from your target. Less fuss, same effect.
+Does this tool sell any thing?
No. It is a read only mirror of your mix. The moves stay yours.
