Savings Goal Formula

PMT = (FV − PV × (1 + r)^n) ÷ (((1 + r)^n − 1) ÷ r)

Where FV = savings target, PV = current savings, r = monthly interest rate (annual rate ÷ 12), n = number of months.

What is a savings goal calculator?

A savings goal calculator helps you translate a financial target — whether it is a house deposit, emergency fund, holiday, or retirement pot — into a concrete monthly action. By entering your target amount, your current balance, an expected annual return, and a time frame, you get the exact monthly contribution required to reach your goal.

The calculation uses the time value of money, recognising that money saved today earns interest and therefore works harder than money saved in the future. Starting early and choosing the highest available interest rate significantly reduces the monthly amount needed, which is why compound interest is often described as the most powerful force in personal finance.

Frequently asked questions

How much should I save each month to reach my goal?
It depends on your target amount, how much you already have saved, the interest rate on your savings account, and your time horizon. This calculator uses the time-value-of-money formula to compute the exact monthly payment needed given all four inputs.
What formula is used to calculate required monthly savings?
The calculator uses the future value of an annuity formula: PMT = (FV − PV × (1 + r)^n) ÷ (((1 + r)^n − 1) ÷ r), where FV is the target, PV is current savings, r is the monthly interest rate, and n is the number of months.
What if I leave the interest rate at 0?
When no interest rate is entered, the calculator performs a simple division: it subtracts current savings from the target and divides by the number of months. This is useful for non-interest-bearing accounts like a basic current account.
Does the calculator account for compound interest?
Yes. The savings goal formula compounds interest monthly. Your existing savings also grow with compound interest over the period, which reduces the monthly contribution you need to make.
Why does the result show $0 instead of a negative number?
If your current savings already exceed the target once interest is applied, the required monthly payment would mathematically be negative, meaning no additional savings are needed. The calculator displays $0.00 in this case to avoid confusion.
How can I reach my savings goal faster?
You can reach your goal faster by increasing your monthly contribution, choosing a savings account with a higher annual interest rate, or extending your time horizon to reduce the required monthly payment. Starting earlier has the greatest compounding benefit over time.
