Model disciplined Bitcoin investing across time, fees, and volatility. Track average cost and portfolio value. Make steadier decisions using consistent purchases through market cycles.
This sample illustrates how recurring buys can build a position over time. Values below are example figures for demonstration only.

1) Periodic Bitcoin price estimate
Future spot price for each contribution period is estimated using compound growth:
Period Growth Rate = (1 + Annual Growth Rate)^(1 / Periods per Year) - 1
Spot Price at Period n = Starting Price × (1 + Period Growth Rate)^n
2) Net amount available to buy Bitcoin
Exchange fees reduce each contribution before purchase:
Net Purchase = Contribution - (Contribution × Fee %)
3) Slippage-adjusted execution price
Slippage raises the actual execution cost relative to the quoted price:
Effective Buy Price = Spot Price × (1 + Slippage %)
4) Bitcoin purchased per period
BTC Bought = Net Purchase ÷ Effective Buy Price
5) Average cost basis
Average Cost per BTC = Total Invested ÷ Total BTC Held
6) Ending portfolio value
Portfolio Value = Total BTC Held × Ending Bitcoin Price
7) Profit and return
Profit / Loss = Portfolio Value - Total Invested
ROI % = (Profit / Loss ÷ Total Invested) × 100
Dollar-cost averaging means buying Bitcoin with fixed amounts at regular intervals. It spreads purchases across time, which can reduce the impact of short-term price swings on your average entry cost.
No. This version uses your entered starting price and projected annual growth rate. That makes it useful for scenario planning, budgeting, and comparing assumptions before investing.
Fees reduce the cash available for each purchase, while slippage increases the actual executed buy price. Both lower the amount of Bitcoin accumulated over time.
It shows how much total money you spent for each full Bitcoin accumulated, including recurring buys and fees. It helps compare your effective entry price with market price.
The comparison shows whether spreading purchases across time helped or hurt versus buying everything at the beginning. Results depend mainly on how prices move after the start date.
Yes. The annual contribution increase field raises your recurring amount once each year. It is useful when you expect salary growth or want a more aggressive accumulation plan later.
It is the Bitcoin price needed for your holdings to equal the total money invested. If market price is above that level, the position is profitable before taxes.
No. It is an educational planning tool. Real market prices, taxes, spreads, and exchange conditions can differ, so investment decisions should include independent research and risk judgment.
