Audited planning profile
This lean three-year profile applies a 0.75× editable baseline across 36 model periods to the cash reserve buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Run an adverse case for inflation, downtime and changing demand over three years.
Returns are not guaranteed; taxes, volatility, sequence risk, liquidity limits and product restrictions require separate inputs or review.
Compare conservative, central and adverse assumptions and verify product fees and tax treatment before investing.
