How to Use the Savings Goal Calculator
The Savings Goal Calculator works backwards from your target to tell you exactly how much you need to save each month (or each week) to hit your goal by a specific date. Whether you're saving for a house deposit, holiday, emergency fund, or big purchase, it removes the guesswork from your saving plan.
Enter your savings target, your current balance, your planned monthly contribution, and your target date. The calculator shows whether you'll reach your goal on time and, if not, how much more you need to save each month. It also accounts for interest you'll earn while saving.
A nuance worth understanding is the difference between nominal and real goals. If you're saving for a purchase 5 years away, inflation will erode your purchasing power. A £20,000 car today might cost £22,500 in 5 years at 2.4% inflation. Consider inflating your target for long-term goals.

Frequently Asked Questions
What is the difference between a savings goal and an emergency fund?
A savings goal has a specific target and timeline (e.g. £10,000 for a car in 18 months). An emergency fund is an ongoing safety net of 3–6 months of expenses kept accessible at all times. Our dedicated emergency fund calculator helps with that specific scenario.
Should I save in a fixed-term or easy-access account?
If your goal date is fixed and you won't need the money earlier, a fixed-term savings account typically offers higher interest. If your timeline is flexible, easy-access accounts provide more flexibility. Compare the AER (Annual Equivalent Rate) to make a fair comparison.
How does interest affect how much I need to save monthly?
The higher the interest rate, the less you need to save monthly to hit the same target. On a £10,000 goal over 2 years: at 2% interest you need £407/month; at 5% you need £397/month — a modest saving. The impact is larger over longer timeframes.
Is it better to save a lump sum or monthly contributions?
Both work, but starting with a lump sum means all that money earns interest from day one. Monthly contributions are more practical for most people. A combination — starting lump sum plus regular contributions — is optimal if you have some savings already.
How do I save more when my budget is tight?
Start by automating savings transfers on payday before you can spend the money. Review subscriptions and discretionary spending. Consider a savings challenge (e.g. the 52-week challenge). Even £50–£100 per month adds up significantly over time.
