How this calculator works
How the projection works
The calculator assumes a constant monthly return derived from the annual rate and deposits at the beginning of each month. Actual markets fluctuate and future returns are not guaranteed.
Try several assumptions
Compare conservative, moderate and optimistic rates instead of relying on one projection. Fees, taxes and missed contributions reduce results.
Frequently asked questions
Can this result predict a trade?
No. It only applies a formula to your assumptions. Market prices, fills, fees and outcomes can differ.
Does TradeCalcZen store my values?
