Savings Goal Calculator

Find out how long it will take to reach your savings goal, or how much you need to save each month to hit a target date.

Setting a concrete savings target dramatically increases your chances of reaching it. Research from the Money and Pensions Service shows that people who set a specific goal save 73% more than those who simply try to put money aside. This calculator turns a vague intention into a clear monthly plan.

Whether you are saving for a house deposit, a wedding, a new car, or an emergency fund, the maths is the same. You need to know your target amount, how much you already have, and either when you want to reach the goal or how much you can save each month.

Interest earnings are factored in using the rate you specify, so the tool accounts for compound growth on your savings. Even a modest interest rate makes a meaningful difference over a multi-year savings plan.

How it works

  1. Enter your savings target and any amount you have already saved.
  2. Choose a mode: calculate how long it takes, or calculate the monthly amount needed by a target date.
  3. View the result with a month-by-month savings projection including interest.

Frequently asked questions

How do I calculate how long it takes to save?▾
Divide your remaining target by your monthly contribution, adjusting for interest. Our calculator factors in compound interest to give you a more accurate timeline than simple division.
Should I include interest in my savings plan?▾
Yes. Even modest interest rates compound over time. A 4% savings rate on regular contributions can add thousands over several years. Always factor interest into your plan for realistic expectations.
What is a realistic savings goal?▾
A good starting point is to save 3-6 months of expenses as an emergency fund. After that, set specific goals: holiday fund, house deposit, retirement. Break large goals into monthly targets.
How much should I save each month?▾
The 50/30/20 rule suggests saving 20% of your after-tax income. However, any amount is better than nothing. Start with what you can afford and increase gradually.
Where should I put my savings?▾
For short-term goals (under 3 years), use a high-interest savings account or Cash ISA. For longer goals (5+ years), consider a Stocks & Shares ISA. For a house deposit, consider a Lifetime ISA for the 25% government bonus.
Does this calculator account for inflation?▾
No. The calculator shows nominal values. If you are saving for something 10+ years away, consider that prices will rise. You may need to save more than the current price suggests.
What if I can save more some months than others?▾
Use your average monthly savings amount. The calculator assumes consistent contributions. In practice, saving more in good months and less in tight months will average out similarly.
Should I pay off debt or save?▾
If your debt interest rate is higher than your savings rate, pay off debt first (except maintaining a small emergency fund). Credit card debt at 20% should be cleared before saving at 4%.
How can I save more money?▾
Track your spending to find cuts, use budgeting apps, set up automatic transfers on payday, cancel unused subscriptions, switch energy and insurance providers, and avoid lifestyle inflation when you get a raise.
Is it better to save weekly or monthly?▾
Monthly is more common and easier to manage with monthly pay. If paid weekly, saving weekly works too. The key is consistency — set up an automatic transfer so you save before you spend.
