Savings Challenge Builder

A savings challenge generated from your target and your timeframe, rather than a fixed grid you have to fit yourself around.

Pick the challenge length, the target, the start date and how the amounts should escalate. The grid rebuilds itself from those four: every period dated, every deposit derived, the cumulative total running alongside. Mark each period done as you pay it in, and Progress reports the percentage and projects a finish date from the pace you have actually kept.

WHAT'S INSIDE

Start Here — how the file works and which cells are yours

Setup — the four inputs that define the challenge, and the per-period amount they produce

Challenge Grid — up to 100 dated periods, deposit and cumulative, with a Done column

Progress — periods completed, saved so far, still to go, percent complete, projected finish

THE PART NOBODY ELSE BUILDS

Three escalation shapes, and all three sum to your target. Flat is the same amount every period. Linear starts small and ramps. Random varies unpredictably around the average, which some people find easier to stick to — and the variation is fixed per period rather than re-rolled each time the file opens, so week nineteen is the same number tomorrow as it was today. A printable 52-week grid asks you to want exactly what it was designed for. This one starts from what you actually need.
