Worked example
To reach 0.1 BTC (10,000,000 satoshis) by buying 50 USD every week at today's price, you need 150 purchases. That takes about 150 weeks and costs 7,500 USD in all.
How it works
Bitcoin still to buy = goal − bitcoin held. Each purchase buys amount ÷ price. Purchases needed = bitcoin still to buy ÷ that, rounded up. Time = (purchases − 1) × the days between purchases: 1 for daily, 7 for weekly, 365.25 ÷ 12 for monthly. The date is today plus that time, and the cost is purchases × amount. The price is held at today's level.
Frequently asked questions
How long does it take to get 1 bitcoin?
It depends on how much you buy and the price. Set the goal to 1, enter what you can buy each week or month, and the calculator gives the purchases, the date and the cost at today's price.
What does stacking sats mean?
Buying small amounts of bitcoin regularly, counted in satoshis, the smallest unit: one hundred millionth of a bitcoin. Many people buy a fixed amount on a schedule rather than trying to time the price.
What if the price changes?
Then the real result differs. A higher price means more money for the same bitcoin and a lower price means less. The calculator holds the price fixed so you can compare plans, not to predict yours.
