How is the required monthly contribution calculated?

The tool takes the amount still needed — target minus what you have already saved — and divides it by the number of months until your deadline. If you instead enter a fixed monthly amount, it divides the remaining amount by that contribution to find how many months the goal will take.

What are the milestones for?

Big goals feel abstract, so the tool marks the 25%, 50%, 75%, and 100% points with the amount and the projected date you reach each. Hitting a concrete milestone is far more motivating than staring at a distant final number, and the dates let you check whether you are on pace.

Does it account for interest?

Optionally. If you enter an annual savings rate, the plan notes the rough interest boost over the period so you can see that a high-yield account shortens the journey. For short goals the effect is small; for multi-year goals it can be meaningful, so it is worth including.

Should I use a separate account for each goal?

Yes — a named, separate account stops goal money from blending into everyday spending and makes progress visible. Automating the monthly transfer on payday is the single highest-impact habit, because money you never see in your current account is money you do not spend.

Is this financial advice?

No. The tool performs simple arithmetic on the figures you enter and formats a plan. It does not recommend products or returns. Rates and your circumstances vary, so treat the output as a planning guide and confirm details with your bank or a qualified adviser.

Turn a vague “I should save for that” into a dated plan

Most savings goals fail not from lack of will but from lack of arithmetic: people never work out what the goal actually costs per month, so it stays a someday wish. This builder fixes that. Give it a target and either a monthly amount or a deadline, and it computes the missing piece, then lays out dated milestones so a £15,000 house deposit becomes “£417 a month, halfway by next spring”.

How it works

The tool runs straightforward savings arithmetic on your inputs:

Remaining     = target − already saved
Monthly mode  : months  = ceil(remaining / monthly contribution)
Deadline mode : monthly = remaining / months until target date
Milestone $   = target × {0.25, 0.50, 0.75, 1.00}
Milestone date= start + (months × milestone fraction)
Interest est. = remaining × (annual rate) × (months / 12) × 0.5

In monthly mode you say how much you can put aside and it tells you how long the goal takes. In deadline mode you set a date and it tells you the contribution required. Either way it places the 25/50/75/100% markers with amounts and projected dates. The optional interest estimate uses a half-period approximation, since your balance grows from zero to the target over time rather than sitting at the full amount.

Tips and example

Saving for a £15,000 deposit with £2,000 already set aside leaves £13,000 to go. At £500 a month that is 26 months, with the halfway mark — £7,500 — landing around month 13. Automate the transfer on payday into a separate, named high-yield account so the money is gone before you can spend it, and let the milestones do the motivational work. For multi-year goals, turn on the interest estimate: a few percent annual yield can quietly shave weeks off the timeline. The figures are planning estimates, so revisit them if your income or the goal changes.
