Home Purchase Calculator

Compare a larger home down payment with using that cash to buy Bitcoin

Compare two ways to use the same cash when buying a home. Adjust the assumptions to see how each strategy changes over time.

How this calculator works

Strategy A applies all available cash toward the home. Strategy B uses half of the available cash for the down payment and invests the other half in Bitcoin. Both strategies use the same home-price, appreciation, mortgage-rate, loan-term, and time-horizon assumptions.

Methodology & assumptions

This calculator compares two uses of the same available cash. Strategy A applies all available cash to the down payment. Strategy B applies half to the down payment and invests the other half in Bitcoin.

Results use standard mortgage amortization and the assumptions selected above. The comparison is designed to make the cost of additional financing visible alongside the modeled growth of the Bitcoin allocation.
