Retiring early (FIRE) in Quidsmith

Game context, not financial advice. This article explains how things work inside Quidsmith, a personal-finance simulation game. The numbers are illustrative and the model is simplified for play. It is not personal financial advice. For decisions about your own money, speak to a regulated adviser.

Your salary runs to 60 in Quidsmith, but you do not have to depend on it that long. Financial independence, reaching the point where your investments could cover your costs, is a real target you can aim for early, and the maths behind it is refreshingly simple.

It all comes down to your savings rate

The single biggest lever is the share of your income you save and invest. A high savings rate does double duty: it grows the pot faster and means you need a smaller pot, because you already live on less. That is why savings rate, far more than salary, decides how soon you reach independence.

Roughly how many years of saving it takes to reach independence at different savings rates, starting from nothing. The rate matters far more than the size of the salary.

The number: about 25 times your costs

A common rule of thumb is that you are independent once your pot reaches around 25 times your annual spending, which corresponds to drawing roughly 4% a year. Spend £20,000 a year and the target is about £500,000. Trim your costs and the target falls with them, which is why frugality accelerates independence twice over.

The pension-lock problem, and the ISA bridge

There is a catch specific to the game: pensions are locked until 57. If you want to stop relying on salary before then, you need accessible money to bridge the gap. That is where the ISA shines, its tax-free growth can be withdrawn at any age. A common early-retirement structure is:

  1. Grab the employer match in the pension, which is free money you never skip.
  2. Pile into the ISA to build a pot you can actually draw on before 57.
  3. Let the pension run to take over from 57 and 68 (State Pension) onward.
Mind the sequence

Retiring early means a longer retirement, which means more exposure to sequence-of-returns risk. Aim for a slightly larger buffer than a 4% draw suggests, keep some flexibility to trim spending in bad years, and remember the game still throws unexpected events at you. Independence is not the finish line; surviving the decades after it is.
