Planners
Free, interactive tools to help you make smarter financial decisions — no spreadsheets, no jargon, just answer a few simple questions.
Why Use Our Financial Planning Tools?
Most financial planning tools assume you already know the jargon — this shouldn’t be the case. Every planner on Market Compass is built the same way: we ask you a handful of plain-English questions, one at a time, and instantly show you a clear, visual answer. No downloading spreadsheets, no formulas to get wrong, and no account or sign-up needed.
All the maths happens right in your own browser. We never see, collect, or store the numbers you enter — you can read more in our Privacy Policy. And because everything’s free, you can come back and try different scenarios as many times as you like, whether you’re comparing mortgage overpayment options or figuring out your FIRE number.
If you’re looking for even more free, impartial financial tools beyond what we offer, MoneyHelper’s tools and calculators (a UK government-backed service) is a great place to look — covering areas like pensions, debt, and benefits that go beyond what our current planners cover.
