Investment calculator
Compound growth, computed honestly: you set the starting amount, the monthly contribution, the horizon — and the assumed annual return. We prefill the return with zero, because any number we chose for you would be a forecast in disguise.
Total contributed
40 000
Growth (your assumption)
0
End value
40 000
A model, not a forecast: the result follows purely from YOUR assumed rate, compounded monthly, before taxes, fees and inflation. No figure here is a prediction or a promise of performance.
Why we prefill no return
Most investment calculators arrive with a friendly 7% already typed in. That number is doing quiet work: it anchors your expectation before you have thought about it. This site publishes no predictions and makes no performance claims — for Bitcoin or anything else — so the return field starts at zero and the assumption is entirely, visibly yours. Negative rates are allowed, because markets fall too.
The mathematics is the standard one: monthly compounding of your assumed annual rate, contributions added each month. Change one input and everything recomputes.
Where BIKENZO fits
A calculator answers "what if my assumption held?". It cannot tell you which assumption to hold — and neither do we. What BIKENZO sells is context for forming your own view on one specific asset: the Bitcoin price plotted against global central-bank liquidity, on real public data, back to 2003. Assumptions in, decisions out — both remain yours at every step.
