Frequently asked questions

Does this budget planner send or share my figures?

No. Your budget is saved only in local storage in your browser. The figures are not sent to Finrato or anyone else.

How are weekly and annual amounts converted to monthly costs?

Weekly amounts are multiplied by 52 and divided by 12. Four-weekly amounts are multiplied by 13 and divided by 12. Quarterly amounts are divided by 3, and annual amounts by 12.

Is the 50/30/20 split a rule I must follow?

No. It is an informational guideline. Household circumstances vary, and the planner's category-to-bucket mapping is approximate.

How to build a budget that survives real life

A budget is not about spending less — it is about knowing where your money goes before the month decides for you. The planner above does the one thing most budgets get wrong: it puts every cost on the same footing by converting weekly, four-weekly, quarterly and annual amounts to a single monthly figure. That is where household budgets quietly fail — the car insurance, the MOT, the Christmas spend and the annual subscriptions never feel like “monthly” money, so they ambush you. Spread across twelve months, they become visible.

Start with take-home, not gross

Budget from what actually lands in your account — after tax, National Insurance and pension. Gross pay is a number you never see. If your income varies (shifts, self-employment, commission), use a cautious average or your lowest recent month, so the plan holds in a lean one rather than only in a good one.

The 50/30/20 guideline — a compass, not a rule

A well-known starting split is 50% of take-home on needs (housing, utilities, food, transport, insurance, minimum debt payments), 30% on wants (eating out, subscriptions, hobbies, holidays) and 20% on savings and clearing debt beyond the minimums. The planner shows your split against these targets. Treat it as a compass: in much of the UK, rent alone breaches 50%, and that is arithmetic, not failure. The value is seeing the gap and deciding deliberately which bucket absorbs it, rather than finding out at the cash machine.

Turning a shortfall into a surplus

Your figures stay on your device

This planner saves everything in your browser only — nothing is sent to us or anyone else, and there is no account to create. Come back on the same device and your budget is still there; clear your browser data and it is gone. That is deliberate: your household finances are nobody's business but yours.

Frequently asked questions

What if my income is different every month?

Budget on a cautious figure — an average of the last three months, or your lowest recent month if things are tight. It is safer for a plan to have room to spare in a good month than to break in a bad one. Revisit the number whenever your situation changes.

Do minimum debt repayments count as a need or a want?

Minimum payments are needs — missing them has real consequences. Anything you pay above the minimum belongs in the 20% savings-and-debt bucket, because clearing debt builds your net worth exactly like saving, often at a better guaranteed return. If money is tight and you can't cover essentials, see our bill prioritiser and get free debt advice before cutting a priority bill.

Is 50/30/20 realistic on a low income?

The lower the income, the larger the share needs consume — that is maths, not a personal failing. Use the split as a direction of travel: if needs take 70%, the goal is nudging that toward 65% over a year through cheaper tariffs, renegotiated bills or shared transport, not forcing a 20% savings rate overnight.
