Scenario Lab+

Stress test your plan

Markets don't hand you six percent a year on schedule. Scenario Lab+ supports industry standard stress testing to reveal your plan's resilience to the unexpected.

Alice's plan, Ontario. A plan has to pass all three tests before it is rated Robust.

Monte Carlo Simulations

Across 1,000 simulations, Monte Carlo randomizes the return in every year of the plan. You'll get a success rate, a median outcome, the balance the best tenth of runs finish on, and the age the money typically runs out in the runs that fail.

Success rate across all runs
Percentile bands, not just an average line
Median depletion age across the runs that fail
911 of 1,000 runs still had money at the end of the plan. The shaded bands are the spread of the rest.

Replayed against real history

Instead of randomizing, replay the plan against every real S&P 500 return sequence since 1928. That is 69 retirement cohorts, one for each start year, run to the end of your horizon. You see how many survived, the best and worst years anyone could have retired into, and a bar per cohort you can click to follow its whole path.

One bar for every year someone could have retired since 1928. Green survived, red ran out.

Because the order matters more than the average

A crash in year two does far more damage than the same crash in year twenty, since the early loss comes out of the balance every later withdrawal depends on. Four real market eras replay that timing against your plan, from the Great Depression to the lost decade, each charted beside your base case with a note on what made those years hard.

Retiring into 1966 meant two oil shocks and fifteen years of flat real returns. The dashed line is the same plan on base assumptions.
Our promise

Why pay for Scenario Lab+?

We built Loonie Nest for our family, colleagues, and friends. Not for the big banks or advertisers. Staying independent keeps us focused on our mission - making financial tools and education accessible for all Canadians.

Your subscription directly funds ongoing development of the planner, and is shaped by feedback from the 14,000+ people who've already built a plan with it.

Loonie Nest is built in Canada, for Canadians. Support 🇨🇦 businesses, workers, and products.

For every household

A plan from a financial advisor can run $3,000 or more. Scenario Lab+ gives you that same depth for $59 a year.

Privacy comes first

Free tools make money from ads, connecting to your bank accounts, or by selling your information. We just sell subscriptions.

Funded by the people who use it

Loonie Nest grows through customers, not outside investors. That keeps us focused on the planner, not someone else's growth targets.

Just tried it out for shifts and kicks and it calculated the same earliest retirement year as my spreadsheets. Great, easy to use tool.

I tried the savings goal calculator (mid 30s here) and found it very easy and clear to understand. I'm a good saver but always been intimidated to figure out how I'm doing for retirement. This made it easy to know I'm doing just fine.

This app was pretty quick to figure things out and really easy to use. App looks polished, the colours look good and it's simple to use.

I'm president of a local union in Langley. Great website. Simple and effective. Looks like a good tool for our members.
