Audited planning profile
This standard five-year profile applies a 1× editable baseline across 60 model periods to the down payment fund buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Use this as the central case, then compare a lean and conservative profile. Treat maintenance, replacement and compounding assumptions as material over five 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.
