How should I calculate my take-home salary?

Enter your monthly take-home pay after tax, National Insurance, and any pension contributions already deducted by your employer. If you're paid weekly, multiply your weekly take-home by 52 and divide by 12. For irregular income, use a conservative monthly average based on the past 3–6 months.

What is a good savings rate?

Financial experts often suggest saving at least 20% of your take-home income, following the popular 50/30/20 rule (50% needs, 30% wants, 20% savings). In practice, even 10–15% is a strong start. Pension contributions count toward your savings rate; the key is consistency over time rather than hitting a specific percentage.

Should I include pension contributions as savings?

Yes. Pension contributions are deferred income that builds wealth for retirement, so they absolutely count as saving. This calculator includes pension contributions in both your savings total and savings rate. Note that some pension contributions are taken from gross pay (before tax), in which case your take-home already reflects this, so enter any remaining pension contributions or additional voluntary contributions.

What should I do if I have a monthly deficit?

First, review your variable expenses (eating out, subscriptions, hobbies, clothing) for easy cuts. Then look at larger fixed costs: switching energy supplier, insurance provider, or broadband deal. Building an emergency fund of 3–6 months' expenses is a priority before aggressively paying down non-urgent debts.

How often should I revisit my budget?

Review monthly to track actuals against your plan, and do a full review when your circumstances change: a pay rise, new fixed contract, or major expense. Many people find that tracking actual spending for just one month reveals surprises that prompt lasting behaviour change.
