We would rather over-explain the method than let an output look more precise than it is. The heuristic is deliberately simple and fully disclosed:
- It has no starting ratio and no rate card. Singapore Stock Loans publishes no loan-to-value band, because loan-to-value is a property of the collateral rather than of the product. The tool begins from a neutral reading of the position and lets the drivers move it.
- It weighs the site's own stated drivers. Liquidity and free float, volatility, market capitalisation implied by position size and sector, concentration, sector character, and recourse are exactly the factors described in how LTV is set on an SGX counter and on the sectors page.
- The drivers pull the same way they do in practice. Thinner liquidity, higher volatility, a larger and more concentrated block, and lighter recourse all point toward a lower advance and a wider buffer; deep liquidity, low volatility, a diversified register, and full recourse allow a higher one.
- The output is always a plain-English verdict — a lower, mid-range, or higher advance — never a ratio and never a sum, and it always carries the illustrative caveat. Tenor is shown as an illustrative band consistent with a defined fixed term and renewal options.
- Nothing is collected. The calculation runs in your browser with a small inline script; no inputs are transmitted, logged, or stored, and there are no network calls.
The tool cannot see your actual counter, its live free float, its traded value, or the day's volatility — all of which a principal reads before setting terms. That is precisely why it names no ratio: any figure it produced would be an assumption wearing the clothes of a term. Treat the result as a way to build intuition about the drivers, and nothing more.
