CAGR shows the average annual growth rate over a period.
Formula: CAGR = (End Value / Start Value)^(1/Years) − 1.
Reach for this tool whenever a financial decision hinges on this type of calculation. Small differences in rate or term become large differences in total cost or return over multi-year horizons — differences that only become visible when you run the actual numbers.
Many financial calculation errors stem from omitting ancillary costs: fees, taxes, insurance, or maintenance. The headline figure (interest rate, monthly payment) is rarely the complete cost of a financial product.
An employee receives a counter-offer from another employer: a £4,000 salary increase but no pension contribution versus the current role's lower salary with 8% employer pension. Running both through the finance calculator shows the true net financial value of each offer.
The stock market has historically returned ~7-10% CAGR.
