Count what arrives.
Use a typical after-tax month. For variable income, use a cautious estimate rather than your best month.

ONE MONTH. THREE VIEWS.
Numbers should move you forward.
This is a hands-on space to ask better questions of your money. The first view shows what is left. The second shows what one change would do. The third gives that remainder a direction.

A little room can become a real plan.
Pick a goal amount and decide how much of this month's remaining amount you would put toward it. The timeline is a planning sketch, not a promise.
GOAL STUDYBASED ON THE MONTH ABOVE
ESTIMATED TIME AT THIS PACE4 months
At $1,400 a month, reaching $5,600 would take about 4 months.
Assumes the same income and spending each month, with no interest, price changes, or unexpected costs. A goal that takes less than one month still displays as one month.

Private by construction. Saved plans remain in this browser’s local storage until you clear them here or in your browser.

05 / THE PRACTICE
Make the estimate useful.
Start with numbers you can recognize. Then treat the result as a question worth checking, not a verdict.
Separate what leaves.
Fixed costs might include housing, utilities, and minimum payments. Other spending covers the flexible part of everyday life.
Give the remainder a job.
Consider a buffer before assigning the entire remainder to a goal. Revisit the plan when income or costs change.
06 / CONTINUE WITH GOOD SOURCES
Take the sketch into real life.
These free Consumer Financial Protection Bureau resources can help you check the estimates against actual spending and think through a savings goal.
07 / PLAIN ANSWERS
Know what this is.
BRASSLINE is a fictional Sly Art Designs showroom concept. Its planning tools run in your browser.
What can I do here?
Enter a month to see what remains, try a different spending amount without changing it, and choose how much of the remainder would go toward an illustrative goal.
Does this connect to an account?
No. This demo does not open accounts, transfer money, or connect to financial institutions.
Are my numbers stored?
Only if you choose “Save this snapshot.” Saved plans stay in local storage inside this browser and are never sent to a server. You can remove any saved plan from the Plan vault.
Is the timeline financial advice?
No. BRASSLINE is not financial advice. It is simple arithmetic based on your estimates and does not account for changing income, debt interest, inflation, emergencies, or other personal factors.
Can I use this plan to make a decision?
Use it to organize questions and estimates. Check the numbers against your real bills, leave room for surprises, and seek qualified help for decisions with serious consequences.
