Loan-to-Invest Calculator
Finance kits
Compare borrowing a lump sum to invest at once against dollar-cost averaging — see the break-even return rate and the gap in annualized returns.
Your real leverage is often higher than you think. Add each holding at its market value and leverage multiple, subtract your debt, and see the true ratio.
Holdings
Enter each position at its current market value, then set its leverage multiple (1× for ordinary stocks/ETFs, 2× or 3× for leveraged ETFs).
Cash & debt
Your exposure
Your investment exposure is 300K — 3.00× your net assets of 100K. Every move in the market hits you as if you held 3.00× your own money.
Stress test
Applies a one-off market drop to your full exposure. Loss = exposure × drop. Because exposure is bigger than your net assets, the percentage hit to your net worth is amplified.A leverage ratio above 1× means a market fall costs you more, in percentage terms, than the fall itself. Borrowing plus leveraged ETFs stacks the effect.
Rebalancing plan
The leverage ratio you want to bring your portfolio down to. 1× means fully invested with no leverage; below 1× means holding a cash buffer.To bring your leverage from 3.00× down to 1.0×, take either path (or mix the two):
Sell about 133K of your portfolio at the current mix, cutting 200K of exposure. The more you sell from your highest-leverage holdings, the less you need to sell.
Add about 200K of fresh cash to repay debt (or borrow less). Exposure stays the same but net assets rise, hitting the same target.
Selling at market value doesn't change your net worth — it just swaps one asset for another (or pays down debt). What actually lowers risk is shrinking your exposure.

The Exposure & Leverage Ratio Calculator answers a question most investors never actually run the numbers on: when you add up borrowed money and leveraged ETFs, how much market risk are you really carrying? Exposure is the total value moving with the market — a plain ETF counts once, a 2× fund counts double — while your leverage ratio divides that exposure by your net assets (everything you own minus what you owe). Borrowing to invest raises the first number without raising the second, and stacking a leveraged ETF on top of a loan multiplies the two together, so the true ratio is routinely higher than people guess. Enter each holding with its leverage multiple, add your cash and debts, and the tool shows your exposure, your real leverage, and a stress test that turns the ratio into a concrete loss when the market drops.
