Start with the collateral you would pledge
Multiply pledged BTC by the assumed price to estimate collateral value. Then multiply that value by your chosen starting loan-to-value percentage. One pledged BTC at $100,000 and a 30% starting LTV gives a modeled total debt limit of $30,000.
This is an illustration, not an offer. A lender determines eligibility, accepted collateral, valuation, fees, and actual proceeds. Bitcoin held in reserve is separate from pledged collateral.
Existing debt uses some of that capacity
If the same collateral already supports $10,000 of debt, the simplified remaining borrowing room is $20,000. This example holds price and debt constant and omits fees, accrued interest, and lender-specific adjustments. A negative difference means debt is already above the chosen target; it does not create additional borrowing capacity.
Compare the starting amount with a harder year
Starting LTV is the ratio of debt to pledged collateral value at one moment. Interest, later draws, repayments, and BTC-price changes alter the path. Open the planner to model those assumptions together, then use Floor Stress to explore lower prices.
Understand LTV before choosing a target, and compare price declines without changing your debt.
