Calculate a savings plan in a minute
The equal-installment plan math — largest-remainder rounding on minor units included — runs entirely in your browser. No data is sent to any server.
A sample calculation — not binding. Real plans are determined by the product definition and the regulation.
Cumulative savings vs. entitlement threshold

| Month | Installment | Cumulative savings | % of amount | Status |

The calculation on this page is a simplified example of the platform’s product catalogue and simulation modules. In production, plans are computed with the full rule set — tariff, campaign, delinquency and withdrawal rules included — pinned to the rule version in force at establishment.

Why is the draw auditable?
The participant list is locked and fingerprinted with SHA-256; the seed is recorded before the draw; the order is derived from the seed with Fisher-Yates. The same list and the same seed always give the same result — an auditor verifies the draw by running it again.
