Amount in US dollars.
Annual saving uses an average 52.1786 weeks per year. Every 4 weeks is not monthly. The example assumes you set the money aside instead of spending it elsewhere.
Your result
Skipping it once a week keeps $6 in your pocket each time.

Future returns are not guaranteed. The growth example uses equal monthly transfers, not the exact dates of skipped purchases.

Make this plan work for you
This calculator shows the annual cost of skipping one habit and the deposit plan that matches it. Enter the cost each time and how often you skip it, then read the projection table.
- Enter the cost each time you would pay for the habit, such as a drink or snack purchase.
- Set how many times you skip it, using the skip once every N weeks input.
- Read the table for money kept in an average year, the equivalent monthly transfer, and deposits over 10 years.
- Download the Excel or PDF version, or open the Google Sheets example copy, to keep your plan.

How to read the projection
The table converts one skipped purchase into a savings plan you can automate. Money kept in an average year tells you what the habit skip is worth over a 52.1786-week year. The equivalent monthly transfer is the matching automatic deposit amount, which is useful because it is easier to automate one monthly transfer than to remember each skip. Deposits over 10 years shows the total you would set aside by hand, and the hypothetical 4% growth row adds a constant nominal rate with deposits at the start of each month. Use these rows to decide whether the skip alone justifies opening a separate savings account or whether you should fold the amount into an existing transfer. Note that skipping every 4 weeks is not the same as monthly, so pick the frequency input that matches your real pattern.
When to adjust your inputs
Start with your actual purchase price, including tax and tip, not a rounded guess. If you usually skip more than once between paydays, change the N weeks value until the frequency matches reality. If your habit cost varies, use the higher price you pay most often so the plan does not fall short. After a month, compare the money you actually moved with the equivalent monthly transfer row; if the amounts drift, update the cost input rather than the growth assumption. The 4% growth row is a fixed hypothetical rate, so treat it as a comparison point, not a forecast, and rerun the calculator whenever prices change.
Frequently asked questions
Do I need an account to use this calculator?
No BudgetTrellis account is required and the calculator runs entirely in your browser. No financial inputs are uploaded.
Can I save my inputs for later?
Yes. The Excel and PDF downloads contain your current browser inputs. Google Sheets opens a copy of the master example and requires a Google account, and it does not transfer your browser inputs.
Is the growth figure guaranteed?
No. The growth row assumes a constant 4% nominal rate with deposits at the start of each month. Actual returns vary, so use it as an educational estimate for comparison.
