The Problem
Households with moderate-to-high incomes face recurring decisions about where to allocate surplus cash — salary sacrifice into pensions, RRSP/TFSA contributions, mortgage offset accounts, or debt repayment. Each option has different tax implications, opportunity costs, and long-term compounding effects that are difficult to compare without specialized knowledge. People frequently turn to online forums for advice that requires personalized financial modeling, not generic rules of thumb.
Potential Solution
A financial decision engine where users input their income, tax bracket, mortgage details, pension scheme rules, and available tax-sheltered accounts. The tool runs side-by-side scenario comparisons showing after-tax outcomes over 5, 10, and 20-year horizons for each allocation strategy. It accounts for employer matching, salary sacrifice tax savings, marginal tax rates, mortgage interest saved, and investment growth assumptions to produce a clear, ranked recommendation.
Why Now?
Rising interest rates have made the mortgage-vs-investing tradeoff genuinely competitive again, while increasingly complex tax-advantaged account rules across countries like the UK, Canada, and Australia leave households paralyzed by optionality. The surge in forum posts seeking personalized allocation advice signals massive unmet demand for automated, jurisdiction-aware financial modeling.
