Latte Factor Calculator FAQ
Everything you need to know about the Latte Factor and what small daily spending really costs over time.
The Latte Factor is a personal finance concept describing how small, regular discretionary purchases, such as a daily coffee, add up to a significant amount of money over time, especially if that money could have been saved or invested instead.
The Latte Factor is calculated by multiplying a small daily expense by the number of times it occurs per week and per year, then projecting that total forward over time, either as a simple running total or, more usefully, as an investment using compound growth.
Cutting small expenses matters most when the saved money is consistently redirected into savings or investments, letting compound growth do the work over many years. Cutting spending without redirecting it elsewhere has a much smaller long-term financial impact.
Many UK long-term calculators use a return assumption between 4% and 7% per year, based on historical average returns for diversified stock market investments such as a global index tracker held inside a Stocks and Shares ISA. Past performance does not guarantee future returns.
This calculator projects a nominal future value based on your chosen growth rate. It does not separately strip out inflation, so the projected figure represents future pounds, which will have somewhat less purchasing power than pounds today.
A Stocks and Shares ISA is a common UK option for long-term investing because investment growth and withdrawals within the annual ISA allowance are free of UK Income Tax and Capital Gains Tax, though all investing carries risk of loss.
