The math other tools skip.

Most calculators guess a flat tax rate. cinder.fi uses the actual federal and provincial or state brackets in every year, then layers benefits and mandatory withdrawals on top.

  • Free

    Real brackets, everywhere

    Federal tax plus all 13 provinces and territories and all 50 US states. Actual brackets, not a flat rate.

  • Free

    Benefits and forced withdrawals

    CPP/OAS and QPP, GIS, Social Security, RRIF minimums and RMDs, with claiming ages you can move.

  • FreePro

    Year by year to age 100

    Balances, income, spending and withdrawals charts are free. The tax, estate, break-even and contribution-room charts are Pro.

  • FreePro

    Scenarios and cinder score

    Free: a 0–100 readiness score and 1 saved what-if scenario, compared side by side with your plan. Pro: unlimited scenarios.

Your budget feeds the plan.

Targets, bank feeds and real spending become inputs to the same projection, so a habit that changes shows up as a retirement date that moves.

  • Free

    Budget plan and spending modes

    Set monthly targets by category, then choose what drives the projection: an estimate, your budget or your actual spending.

  • FreePro

    Bank sync

    Plaid sync is free for 1 account at 1 institution. Pro syncs every account at every institution.

  • FreePro

    YNAB and statement import

  • FreePro

    Bills, rules and cash flow

    Recurring bills, categorization rules and a 60-day cash-flow forecast are free, with 90 days of history. Pro keeps the full ledger.

Find the best path, then break it.

The optimizer searches for the lowest lifetime tax. The stress test replays your plan through random markets and real history to see how often it holds.

  • Free preview

    Strategy optimizer

    Tests thousands of combinations of claiming age, withdrawal order, RRSP meltdown or Roth conversions, TFSA use and spousal splits. Free shows what you could save; Pro applies it.

  • Free preview

    Monte Carlo

    Randomized markets on your plan. Free shows your odds and the middle 80% of outcomes; Pro runs more markets and opens the full distribution, from worst case to best.

  • Free preview

    Historical backtesting

    Replay your plan through real markets back to 1928. Free shows the success rate; Pro opens every window year by year.

Each account is modeled with its own tax rules and rolled into a single net worth that feeds the plan.
