Will your money last as long as you do?

Most people can't answer that. Not because they haven't thought about it - because nothing they've tried gives them a real answer.

Plannng takes your actual financial picture - what you earn, what you've saved, what you're putting away - and shows you whether it's enough. Not a rough guess. A detailed projection you can trust, because you can see exactly how it's calculated.

Or try one of our free UK calculators: how much do I need to retire? · salary sacrifice impact

I've spent 20 years building products inside retail investment firms. And when I sat down to plan my own retirement, I couldn't answer the most basic question: how long will my money last?

The tools I found either gave me a single number with no way to check the maths, or buried me in jargon before I got anywhere useful. Nothing let me start simple and then dig deeper on my own terms.

So I built the one I actually wanted. One that answers the question clearly - then lets you go as deep as you want. Change your retirement age and see what happens. Test what a bad decade in the markets would do to your plan. See every tax calculation, every assumption, every year laid out. Your retirement, your numbers, nothing hidden.

A clear answer

Your wealth projected forward year by year - how it grows while you're working, how it draws down in retirement, and whether it lasts. In today's money, with tax and inflation accounted for.

Tested against reality

One projection assumes everything goes to plan. Life doesn't. Plannng runs your plan through hundreds of different market conditions and tells you the probability your money lasts - not just the best case.

What-if, in real time

What if you retired two years earlier? Contributed an extra £200 a month? Hit a rough patch in the markets at 60? Change any variable, see the impact instantly, compare it against your current plan.

Plan as a couple

Why we ask for your details

A projection is only as good as what goes into it. We ask for your income, pensions, savings, and expenses so the answer is based on your life - not a national average. Start with the basics, add detail over time.
