The same printable grid works for biweekly savers: tick two boxes after each payday, or edit amounts so only every other week carries a deposit.
How the 52-week challenge works
Pick a weekly plan: classic rising amounts, a fixed deposit every week, or a custom start amount plus increment. Mark each week when you transfer the money. Totals and the progress chart update immediately, and you can edit any week if life gets uneven.
Use the printable view for a fridge-friendly grid. Everything stays on this device in local storage until you reset it.
Private by design
Week52 has no server-side processing of your challenge. Your amounts and checkmarks never leave this browser.
Frequently asked questions
How many deposits in a biweekly year?
Most years have 26 biweekly paychecks; some have 27. Plan for 26 and adjust if you get an extra one.
Should I double classic week amounts?
You can. Set fixed mode to twice your weekly target, or keep classic amounts and mark two weeks per payday.
Can I save the plan across devices?
Not automatically. Data stays in this browser. Export is not built yet; print or screenshot if you need a backup.
Does Week52 upload my savings data?
No. Progress is stored only in your browser's local storage on this device.
Is Week52 free to use?
Yes. The tracker, printable grid and all modes are free with no sign-up.
