How to Calculate Savings?

1. Enter your current savings amount (optional)
2. Select savings frequency (weekly, monthly, or yearly)
3. Enter regular savings amount
4. Enter savings period in months
5. Enter annual real return rate (optional)
6. Click "Calculate Savings"

The results will show:
- Total savings amount
- Total contributions amount
- Total return amount
- Monthly savings amount

Note: If annual real return rate is not entered, only contributions will be summed.

Projecting what regular saving adds up to

A savings projection is a sum of two things: what you already hold, and a stream of future contributions. Both grow, but at different rates, because money paid in later has less time to compound. This page sets out the arithmetic and the assumptions that make projections optimistic.

Formula

FV = P x (1 + r)^n + C x [((1 + r)^n - 1) / r]

P is the starting balance, C the regular contribution, r the rate per period, and n the number of periods. Rate and contribution must share the same period.

The two halves of the calculation

The first term is straightforward compound growth on what you already have. The second is an annuity: each contribution compounds only for the periods remaining after it is paid in, so the first payment does most of the work and the last does almost none.

This is why starting early beats contributing more later by a wide margin. Saving 200 a month for 30 years at 5% produces roughly 166,000. Saving 400 a month for 15 years - the same total paid in - produces about 107,000.

The formula above assumes contributions at the end of each period. Paying at the start of each period instead multiplies the annuity term by (1 + r), which adds a few percent over long horizons.

Compounding frequency is not a rounding detail

A nominal 6% compounded monthly is not 6% a year. The effective annual rate is (1 + 0.06/12)^12 - 1 = 6.17%. Over 25 years that gap is worth roughly 4% of the final balance.

When comparing products, use the effective annual rate - published as AER in the UK, APY in the US, and TAEG or equivalent in the EU - rather than the headline nominal rate. Providers are generally required to disclose it.

What a nominal projection quietly ignores

Every simple projection, including this one, overstates the outcome unless you adjust for the following.

Inflation. At 2.5% a year, money halves in purchasing power in about 28 years. Subtract inflation from your rate to get a result in today's money.
Tax on interest or gains, which in most jurisdictions applies annually rather than at the end.
Platform and fund charges. A 1% annual fee removes roughly 20% of the final balance over 30 years.
Rate variability. Cash rates move; the projection assumes one fixed rate for the whole term.
Contribution gaps. Real savers miss payments, and the formula assumes none are missed.

Worked example

Starting balance 5,000, contributing 300 a month for 20 years at a nominal 5% compounded monthly. Here r = 0.05/12 = 0.0041667 and n = 240.

Growth on the starting balance: 5,000 x (1.0041667)^240 = 13,589. Growth on contributions: 300 x [((1.0041667)^240 - 1) / 0.0041667] = 123,310. Projected total: 136,899, of which 77,000 was paid in and 59,899 is growth.

Adjusted for 2.5% inflation, the real value in today's money is roughly 83,500. Both figures are true; only one of them tells you what you can buy.

What 200 per month becomes at different rates

Term	2% a year	5% a year	8% a year
10 years	26,550	31,050	36,590
20 years	58,960	82,210	117,800
30 years	98,530	166,450	298,070
40 years	146,850	305,200	698,200

Contributions monthly at period end, compounded monthly, no fees or tax. Rounded to the nearest 10.

Frequently Asked Questions

No, it returns a nominal figure. To get a result in today's purchasing power, enter your expected return minus expected inflation - for example 5% growth against 2.5% inflation becomes roughly 2.4% real.

Divide 72 by the annual percentage rate to estimate the years needed to double your money. At 6% that is 12 years. It is accurate to within a few percent for rates between roughly 4% and 12%.

Start-of-period payments earn one extra period of interest each, which typically adds 3 to 6% over a long term. Most workplace pension contributions land mid-month, so end-of-period is the more conservative assumption.

Usually compounding frequency, fee deduction, or the timing of contributions within the period. Banks also often project net of basic-rate tax, which this calculation does not deduct.

The arithmetic is the same, but the assumption of a constant rate is far weaker for investments. Sequence of returns matters: the same average return produces different outcomes depending on when the bad years fall.
