Calculator - When To Retire And How To Use Your Retirement Savings And Maximize Government Retirement Benefits

You spent thirty years figuring out how to save. Nobody tells you the withdrawal order matters just as much - pull from the wrong account first and you can hand back thousands in OAS clawback, or walk right past GIS money you were entitled to.

After the background work for the recent posts on CPP, OAS, and RRSP withdrawals (also a bit of GIS in that post), and yes, with some AI help on the build, I put together a drawdown calculator to answer the question those posts kept circling - when can you retire, and in what order should you spend? It tests three sequencing strategies against your actual numbers (the GIS play, the bracket smoother, and the clawback defence) and tells you which one wins, plus the earliest retirement age your portfolio can support.

The usual caveat, and I mean it - I'm not a tax expert or a financial planner. Treat this as general guidance and a way to ask better questions - then confirm the plan with a professional before you act on it.

Drawdown Sequencer — Optimized For Freedom

The Drawdown Sequencer

This tool answers the hard question - what order do you spend your retirement savings in, and when do you turn on CPP and OAS so the government programs work for you instead of against you? Everything runs in today's dollars, using 2026 rules.

What this tool assumes (read this part - it matters):
  • 2026 program figures: CPP max at 65 of $1,507.65/mo, OAS of $740.09/mo (65-74) and $814.10/mo (75+), GIS single max of $1,105.43/mo, OAS recovery threshold of $95,323 of 2026 net income. Benefits and thresholds are indexed, so in real terms we hold them flat - a reasonable planning assumption.
  • CPP adjusts -0.6%/month before 65 and +0.7%/month after 65. OAS defers at +0.6%/month to 70 and gets the 10% bump at 75. GIS shrinks roughly 50 cents per dollar of non-OAS taxable income and requires OAS to be started.
  • Taxes use 2026 federal brackets (14% bottom rate), your province's basic brackets and personal amount, the age amount, and the $2,000 pension income credit from 65. Provincial surtaxes, health premiums, and dividend credits are not modelled - treat provincial tax as approximate.
  • RRIF minimums start the year you turn 72 (conversion at 71). Non-registered withdrawals realize capital gains at a 50% inclusion rate on your gain percentage. TFSA re-contributions during the RRSP meltdown are assumed to have room available.
  • Strategies are ranked by after-tax estate value: remaining RRSP/RRIF is valued at 75 cents on the dollar and non-registered at its value net of deferred capital gains tax, because a TFSA dollar is worth more than an RRSP dollar at the finish line.
  • This models one person. Couples change the GIS math and unlock income splitting - that's a bigger conversation (and a future version of this tool).
  • This is a planning model, not advice. Confirm your own numbers in My Service Canada Account and with the CRA before acting.
