The Problem

People facing major financial decisions often have assets, debt, mortgages, retirement accounts, family obligations, and emotional constraints all tangled together. They struggle to compare options like paying down a mortgage, investing extra cash, refinancing, retiring early, helping family, or preserving liquidity without paying for a full advisor engagement.

Potential Solution

A web app lets users enter their full financial picture, then build side-by-side scenarios for mortgage payoff, refinancing, investing, retirement timing, inheritance management, debt consolidation, and home purchases. The tool projects cash flow, net worth, risk, tax-sensitive account impacts, liquidity, and retirement sustainability, then highlights tradeoffs and suggested next actions.

Why Now?

Higher interest rates, volatile markets, aging parents, inheritance transfers, and delayed retirement decisions are making household finance choices more complex. Consumers increasingly want self-serve financial planning tools before deciding whether to hire an advisor.

Mortgage vs Bank of mum and dad
Hi all I am a long time lurker into this sub but this is my first post, as I need a bit of specific advice regarding my first home purchase, as someone who is very nervous about spending even a penny, to the point where this has cost me thousands (in rent, indecisiveness with savings accounts, etc). I (32F) am looking to buy a flat, up to £250 000, and I have saved about £145 000 deposit (over the last 7 years), which is spread across NS&I, ISA and current account. My current annual income is £82k, but with AI stealing jobs left, right and centre, I feel like this privilege is not a given. I am in the very lucky position to have two options: \-**Get a mortgage -** this option is less desirable for me as I have been brought up with the absolute fear of borrowing, and I think I would not be able to ever catch sleep knowing I owe \~100k+ to the bank. I also am quite frugal, so the thought of spending £35k+ on this is making me sick \-**Get a loan from my parents -** they offered this and while I know they can afford it, they are not incredibly rich, where they wouldn't feel it. I will, of course, try to pay it back as soon as possible, and would feel slightly less stressed than if I took a mortgage. Problem with this is that my parents live in an EU country, where we are from, and all of their money is there; they have no ties to the UK and have never lived here. This concerns me, as I have read horror stories, on this sub and a few others, where large foreign sums are involved in a home purchase. My parents' money comes from 40+ years of hard work, from which my dad recently retired, and is all legal and traceable. I am so incredibly stressed and feel like I am yet again about to make a financial mistake, despite overthinking everything multiple times. My parents cannot advice me on what to do, as they don't understand the British system. What is your advise?

Retirement planning
my wife and I are doing well compared with many I think but nonetheless I’d appreciate some advice. my wife is 59 and I’m 52. we have investment assets of about 1.8M, and a house worth about 2.8M. I earn 230k pa and she contracts for about 200k a year. we still have a mortgage of $250k She is sick of the grind and would like to retire. I’m not ready to retire and will probably continue till 60 perhaps longer. I’m worried (probably irrationally) that we won’t have sufficient funds to sustain a high quality retirement. should I be worried?
