Retirement saving simulator

Work out the target in the retirement target calculator first, then use the button at the bottom to carry it here — the shortfall and how far along you are appear together. Adjusting the monthly amount until you reach 100% is the easiest way to use it.

3–4% for deposit-heavy saving, or a long-run 6–8% with a large equity share. Real returns swing a lot from year to year, so it is safer to assume the low end and be pleasantly surprised.

Use it if you plan to raise what you save as your salary rises. Set to 3%, contributions grow 3% every year. If a large amount is hard to start with, this makes the plan more realistic.

₩800m in 25 years does not buy what ₩800m buys now. Discounting by inflation gives what it is worth in today's money, and that is the number to look at when judging the standard of living it supports.

The longer the horizon, the more the return dominates the result. The same saving plan at 3% and at 9% often ends more than twice as far apart after 25 years. Rather than trying to pick the right rate, see whether the plan survives across the range. If it reaches the target even in the pessimistic case, it is a sturdy plan.

Once a target is carried over, a table shows what you need at each age to stay on course. Comparing your actual savings against it each year tells you immediately whether the plan is on track. The monthly amount needed to reach the target works backwards from where you are now.

Existing savings go in once, combined, and only the monthly contributions are split between the two of you. The money is invested as one pot, so after combining, the maths is exactly the same as for one person. If you track who contributes what, enter it that way; the monthly amount needed to reach the target then comes out as a combined figure.
