Calculator
Recurring habit cost (month and year)
Estimates only. Not financial advice. Your inputs stay in this browser.
This calculator totals everyday repeats—coffee, lunch out, transit taps, small errands—by amount and how often they happen, so you see monthly and yearly weight from rhythm alone. Invoiced subscriptions belong in Subscription stack, not here. Normalised estimates in your browser, no sign-in.
One list for the stuff you do on repeat. Edit the seeds or add rows—totals update as you type.
Changing display currency approximately converts row prices using static, manually maintained rates in your browser—no live FX feed.

How it works
Each row has a label, an amount, and how often it happens. We normalize everything to a monthly figure, add it up, and multiply by twelve for a yearly view. The short list at the bottom is the largest lines by monthly weight—just weight, not a verdict.
The seed amounts are a starting sketch; overwrite them to match your city and your habits. Rows without a label are ignored.
How frequencies convert
- Daily → multiply by average days per month (365 ÷ 12).
- Weekly → multiply by 52 ÷ 12 for a typical month.
- Monthly → as entered; yearly → divide by 12.
