QuantRidge vs ProjectionLab
Scenario-driven financial modelling with an unusually good free tier.
What each one is for
Playing out "what if" properly — career breaks, moves, early retirement — with Monte Carlo and historical backtesting rather than a single straight-line projection. The interface is the nicest in this category.
Running a taxable portfolio with the tax consequences attached — cost basis across every account, wash-sale warnings before the repurchase, harvestable losses, Roth conversion room against bracket thresholds, and a Form 8949 your preparer can file from.
On pricing: Free tier available.
Choose ProjectionLab if
You enjoy building the model yourself and want to compare several futures side by side.
We would rather say that here than have you find it out a month after subscribing to the wrong thing.
Where QuantRidge differs
ProjectionLab is a modelling environment you feed. QuantRidge derives the inputs from your linked accounts and then acts on them — the model and the tax engine looking at the same positions.
The thing ProjectionLab cannot offer
ProjectionLab is the closest tool on this map to how we work — small, responsive, and visibly shaped by its users. We are not going to pretend otherwise. The difference is subject rather than stage: it models the decades ahead, where we start from the tax bill your current positions have already created.
QuantRidge is small enough that one person's problem can become a feature. The Founding 50 is built around exactly that: 50 accounts at $40/month for 12 months, in exchange for telling us what is missing. We build it and you watch it ship. Month 13 renews at $175, which we would rather say here than in a footnote.
Questions people ask
Is QuantRidge a replacement for ProjectionLab?
Not always, and this page says where it is not. You enjoy building the model yourself and want to compare several futures side by side. If that describes you, ProjectionLab is the better choice and plenty of people run both.
What does QuantRidge cost?
$175 a month for individuals, flat, with a 14-day free trial and no percentage of your assets. A limited Founding 50 offer is open: the next 50 approved accounts pay $40/month for 12 months, then renew at the $175 list price.
Can I run QuantRidge and ProjectionLab together?
Yes, and for some people that is the right setup rather than a compromise. What ProjectionLab is for: Playing out "what if" properly — career breaks, moves, early retirement — with Monte Carlo and historical backtesting rather than a single straight-line projection. The interface is the nicest in this category. QuantRidge connects to brokerages read-only and does not touch anything ProjectionLab is doing, so running both costs you nothing beyond the second subscription.
Does QuantRidge manage my money?
No. QuantRidge is software, not a Registered Investment Adviser, broker or custodian. Brokerage connections are read-only — it can see positions and transactions but cannot trade or move money. Your money stays where it is.
