Multi-Asset Portfolio Calculator - Build your portfolio. Simulate real returns. Year by year.

Most investment calculators assume a single average return. But real portfolios combine multiple assets — stocks, bonds, crypto — each performing differently. This tool lets you simulate a multi-asset portfolio using historical average returns or your own custom rates. Add monthly or yearly contributions and see how your portfolio grows year by year under different scenarios.

Hey everyone, I built this because I couldn’t find a portfolio calculator that actually reflects how investing works in real life. Most tools assume a single average return, which felt too simplified — especially if you're combining multiple assets like stocks, bonds, or crypto. I wanted something where I can: - mix different assets - adjust contributions over time - and actually see how the portfolio evolves year by year So I built this tool initially for myself, and then decided to clean it up and share it. Right now it supports historical average returns per asset, but you can also define your own custom assets and expected rates. I’m especially curious: - does this feel realistic enough for your use case? - what would you add or change? Happy to answer any questions — and thanks for checking it out.
