The 2020s cash renaissance restored meaningful nominal yields on deposits and bills — a planning tool, not proof that cash beats productive assets forever. This atlas page keeps the focus on mechanisms you can reason about: rates, time, contributions, costs and behaviour — not stock tips or promised yields.
Cash renaissance (2020s): keep the definition tight, the units dated, and the costs visible — then the “magic” looks like arithmetic with a long clock. Levers differ in how much control you have. Markets set many rates; households set savings rates, fee tolerance and whether they stay invested.
Mark each measure High, Any or Low for what you want. The fit number moves with every mark, and your marks follow you to the next page in this app.

Cash renaissance (2020s): keep the definition tight, the units dated, and the costs visible — then the “magic” looks like arithmetic with a long clock. Levers differ in how much control you have. Markets set many rates; households set savings rates, fee tolerance and whether they stay invested.
The useful math is small: compound growth, present value, and adjustments for fees or inflation. Complexity usually arrives from products, not from the core identities. With regular end-of-period contribution C: FV ≈ C × [((1+r)^n − 1) / r] when r ≠ 0.
r_real ≈ r_nominal − i, with i the inflation rate; prefer the Fisher form for precision. €10,000 at 6% for 20 years → about €32,100 before fees/tax. Halve the rate to 3% and the same horizon yields roughly €18,100.
