One-off planning tool

Give the big thing
its own plan.

The trip, wedding, baby, or repair is not a bad month. Add up the costs and see what to save each month. Adjust the total or the date as you go.

Start with what you know today. You can add the easy-to-miss parts next.

The honest total is kinder than the surprise total.

Open the extra details for a reminder of costs you might have missed. A new child may change income before it changes spending. A home project may require somewhere else to sleep. A trip may need pet care and a quiet week afterward. Finding those costs now gives you time to plan for them.

Worked example. A $3,800 trip with $950 saved leaves $2,850. Six deposits are $475 each. Three deposits are $950. The event did not become “bad”—the timeline changed the monthly tradeoff.
How this works

Remaining amount is the target minus what is already set aside, never below zero. Required monthly savings is that amount divided across the remaining end-of-month deposits, rounded up to the cent.
